Enhanced Precision Distribution<br \/>\nThe fixed 1:2.78 ratio ensures repeatable, calibrated rotational output at every PTO cycle, enabling uniform fertilizer distribution across the spread width. Consistent output speed eliminates hot spots and skip zones, directly reducing over-application. Over a full season, precision spreading translates to measurable savings on input costs while protecting soil health from nutrient imbalance.<\/p>\n<p>2. Industrial-Grade Durability<br \/>\nThe aluminium housing resists corrosion from fertilizer chemicals, moisture, and field debris without the weight penalty of cast iron. Internal components are precision-machined from hardened steel, with oil seals and sealed bearings that block dust and water ingress. This fertilizer spreader gearbox is built to endure thousands of operating hours across multiple growing seasons in the harshest field conditions.<\/p>\n<p>3. Optimized Fuel Efficiency<br \/>\nPr\u00e4zise Zahnradpaarung und \u00d6lbadschmierung minimieren die inneren Reibungsverluste und gew\u00e4hrleisten, dass nahezu die gesamte Zapfwellenleistung des Traktors auf den Streumechanismus \u00fcbertragen wird. Dies f\u00fchrt zu einer geringeren Motorbelastung bei gleicher Streugeschwindigkeit. Landwirte mit gro\u00dfen Fl\u00e4chen berichten von messbaren Kraftstoffeinsparungen pro Hektar im Vergleich zu verschlissenen oder schlecht abgestimmten Getriebealternativen f\u00fcr landwirtschaftliche Anwendungen. Dadurch wird die Wirtschaftlichkeit jedes Streuvorgangs verbessert.<\/p>\n<p>4. Broad Application Versatility<br \/>\nDieses Landwirtschaftsgetriebe f\u00fcr D\u00fcngerstreuer ist kompatibel mit NPK-Granulatmischungen, Harnstoffgranulat, Kalkgranulat, organischem Kompost und verschiedenen Streuerkonfigurationen und passt sich so unterschiedlichen Materialarten und Gel\u00e4ndeprofilen an. Der standardm\u00e4\u00dfige 1-3\/8\u2033-Sechszahn-Zapfwellenanschluss und die 22-mm-Abtriebswelle erm\u00f6glichen die Verwendung einer Vielzahl von Streuscheiben und machen es damit zu einer echten Allround-L\u00f6sung f\u00fcr Mischkulturbetriebe und vielf\u00e4ltige Einsatzgebiete.<\/p>\n<p>5. Geringer Wartungsaufwand<br \/>\nThe oil-bath lubrication system bathes all gears and bearings in a continuous film of 80W-90 gear oil, eliminating grease nipple schedules and reducing service visits. With the first oil change required only at 50-70 hours and subsequent intervals at 500 hours or annually, maintenance demands are minimal. Modular design means individual fertilizer spreader gearbox parts such as seals and bearings are readily replaceable without full gearbox removal.<\/p>\n<p>6. Direct Comer L-25A Compatibility<br \/>\nEngineered as a bolt-on replacement for the original Comer L-25A gearbox, this unit matches OEM mounting dimensions, shaft diameters, and spline counts precisely. Operators can swap in the CMN Transmission L-25A without modifying spreader frames, PTO drivelines, or disc mounts. This compatibility cuts machine downtime during the critical spreading season, making it the preferred choice for fleet managers seeking cost-effective, reliable spares from trusted <a href=\"https:\/\/korea-transmission.com\/de\/fertilizer-spreader-gearbox\/\"><strong>D\u00fcngerstreuergetriebe<\/strong><\/a> manufacturers.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8006 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1-2.78.webp\" alt=\"L-25A D\u00fcngerstreuer-Getriebe 1-2,78\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1-2.78.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1-2.78-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Working Principle<\/h2>\n<p>Die Kraft\u00fcbertragung beginnt an der Zapfwelle des Traktors, die mit der branchen\u00fcblichen Drehzahl von 540 U\/min rotiert. Der Zapfwellenantrieb ist \u00fcber eine 1-3\/8\u2033-Sechszahnkupplung mit der Getriebeeingangswelle verbunden, wodurch die beiden Wellen sicher miteinander verbunden werden. Diese standardisierte Schnittstelle gew\u00e4hrleistet die Kompatibilit\u00e4t mit einer Vielzahl von Traktormarken und -modellen. Sobald der Traktormotor die Zapfwelle einkuppelt, flie\u00dft die Rotationsenergie kontinuierlich \u00fcber die Kupplung in die Getriebeeingangswelle des L-25A-Getriebes und startet so den gesamten Kraftumwandlungsprozess. Die Eingangswelle ist in Pr\u00e4zisionslagern gelagert, die die im Feldeinsatz entstehenden Radial- und Axialkr\u00e4fte aufnehmen.<\/p>\n<p>Once inside the housing, input torque passes through a matched pair of precision-cut bevel gears at the heart of this fertilizer distributor gearbox. The 1:2.78 gear ratio increases rotational speed from the 540 RPM tractor PTO to an output of approximately 1,501 RPM, which is ideal for driving centrifugal spreading discs at the speed needed for accurate lateral distribution of granular or pelleted fertilizers. Bevel gear geometry also changes the torque direction by 90 degrees in some configurations, allowing the output shaft to be oriented perpendicular to the input. The gear mesh is optimized for quiet, low-vibration operation even at maximum load.<\/p>\n<p>The output shaft, measuring 22 mm in outside diameter, transmits up to 31 N\u00b7m of torque directly to the spinner disc assembly or agitator mechanism mounted on the spreader frame. This torque level is engineered specifically for the resistance forces encountered when accelerating fertilizer granules from the disc surface at the spreading speed required for uniform lateral distribution across swath widths of several meters. The output shaft is supported by a heavy-duty sealed bearing that withstands both the continuous rotational load and the intermittent shock loads caused by uneven fertilizer flow or material bridging in the hopper. Stable output speed ensures repeatable spreading patterns run after run.<\/p>\n<p>The aluminium housing is partially filled with 80W-90 gear oil to a maximum capacity of 0.35 litres. As the gears rotate, they carry a continuous film of oil across all contact surfaces, reducing friction, dissipating heat, and extending component life far beyond what grease-packed alternatives can achieve. The oil-bath system requires no external pump and operates silently under all load conditions. The correct fertilizer spreader gearbox oil level should be verified before each spreading season and after the first 50-70 hours of operation. Subsequent oil changes at 500-hour or annual intervals keep the lubrication film in peak condition and prevent accelerated gear and bearing wear caused by degraded lubricants.<\/p>\n<p>High-quality lip seals fitted to both input and output shaft bores prevent fertilizer dust, field debris, and moisture from entering the gearbox interior. Fertilizer chemicals, particularly nitrogen-based compounds and lime, are highly corrosive when in contact with unprotected metal surfaces. The dual-lip seal design maintains positive exclusion of contamination even during prolonged operation in dusty conditions or when the spreader is washed down with high-pressure water. The aluminium housing itself provides inherent corrosion resistance, and an epoxy-coated finish further protects external surfaces. Together, these measures ensure the gearbox interior remains clean, dry, and properly lubricated throughout its service life.<\/p>\n<p>In field conditions, foreign objects, hopper blockages, or disc jamming can cause sudden torque spikes that would otherwise damage internal gears or the tractor driveline. The L-25A gearbox is designed to operate within its rated 5.2 kW \/ 31 N\u00b7m envelope, and is typically paired with an upstream PTO shaft fitted with a slip clutch or shear bolt safety device. When torque exceeds the preset limit, the slip clutch disengages momentarily, preventing the overload impulse from reaching the gearbox. This protective pairing between the fertilizer spreader gearbox and the PTO safety device safeguards the most expensive drivetrain components and minimizes costly downtime during peak-season spreading operations.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8093 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2.webp\" alt=\"Anwendungen f\u00fcr Getriebe von D\u00fcngerstreuern\" width=\"1200\" height=\"900\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2-980x735.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2-480x360.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Anwendungsbereiche des D\u00fcngerstreuergetriebes<\/h2>\n<div>\n<h3>Broadacre Crop Farming<\/h3>\n<p>Essential for the uniform application of granular NPK fertilizers across large cereal, oilseed, and pulse crops.

Safety Preparation and Machine Isolation<br \/>\nBefore beginning any gearbox removal work, disengage the tractor PTO and shut down the tractor engine completely. Apply the parking brake, remove the ignition key, and wait for all rotating components to come to a full stop. Place wheel chocks under tractor wheels and spreader axle. Disconnect the PTO driveshaft from both the tractor output and the gearbox input. This full isolation procedure prevents accidental PTO engagement during the removal process, which could cause severe injury.<\/p>\n<p>2. Altes Getriebe\u00f6l ablassen.<br \/>\nPosition a suitable drain pan beneath the old gearbox. Remove the oil drain plug (typically at the lowest point of the housing) and allow all gear oil to drain completely. Proper oil disposal in accordance with local environmental regulations is required. Draining before removal prevents spillage on the spreader frame and into the soil. Note the condition and color of the drained oil, as excessive contamination or metal particles indicate internal wear that may have contributed to gearbox failure.<\/p>\n<p>3. Remove the Spreading Disc or Output Coupling<br \/>\nUsing appropriate spanners, remove the retaining nut or bolt securing the spreading disc, vane assembly, or output coupling to the gearbox output shaft. Mark the disc position relative to the shaft before removal if a keyway or splined connection is used, to ensure correct angular alignment during reinstallation. Set the disc and all fasteners aside in a clean location. Inspect the output shaft bore for signs of fretting, corrosion, or wear caused by a loose disc connection on the previous unit.<\/p>\n<p>4. Unbolt and Remove the Old Gearbox<br \/>\nSupport the old gearbox weight manually or with a suitable support stand before removing the mounting flange bolts. Undo each mounting bolt in a diagonal sequence to release clamping load evenly. Once all bolts are removed, slide the gearbox forward to disengage it from any locating dowels or the spreader frame boss. Clean the mounting face on the spreader frame thoroughly with a wire brush and rag, removing all traces of old gasket material, rust, and fertilizer residue before fitting the replacement unit.<\/p>\n<p>5. Inspect PTO Driveline Components<br \/>\nBefore installing the new L-25A gearbox, inspect the PTO driveshaft, safety shield, slip clutch, and cross-joint assembly for wear or damage. Replace any worn universal joints, cracked guards, or slipping clutch discs. Installing a new gearbox onto a worn driveline transfers vibration and shock loads into the new unit, accelerating bearing and gear wear. This inspection step is especially important if the previous gearbox failed due to overload, as the PTO driveline is often damaged in the same event.<\/p>\n<p>6. Install and Torque the New L-25A Gearbox<br \/>\nPosition the new CMN Transmission L-25A gearbox onto the clean spreader frame mounting face, aligning the flange holes and any locating dowels. Apply a thin film of anti-seize compound to the mounting bolt threads to prevent future corrosion-induced seizure. Insert all mounting bolts and tighten them in a diagonal sequence to the manufacturer-specified torque (typically 25-35 N\u00b7m for M8 grade 8.8 fasteners). Do not over-torque, as this can distort the aluminium flange and cause misalignment of the internal gear mesh.<\/p>\n<p>7. Fill with Fresh 80W-90 Gear Oil<br \/>\nRemove the oil fill plug and pour SAE 80W-90 gear oil into the gearbox to the correct level, not exceeding the 0.35-litre maximum capacity. Use the oil level check plug to confirm the correct fertilizer spreader gearbox oil level before reinstalling the fill plug. Correct fill level is critical: overfilling causes seal blowout and leaks, while underfilling starves bearings and gears of lubrication, leading to rapid wear. Replace the fill plug and tighten firmly, then wipe away any spilled oil from the housing exterior.<\/p>\n<p>8. Reconnect PTO and Run-In Check<br \/>\nReattach the spreading disc and PTO driveshaft. Reconnect the PTO driveline, ensuring the safety shield is correctly positioned and secured. Start the tractor and engage PTO at idle speed (low RPM) for a 5-minute unloaded run-in period. Listen for abnormal noise and check for oil leaks at all seal points. After the run-in, shut down the tractor and re-inspect all mounting bolts for tightness. The first oil change should be scheduled at 50-70 operating hours to flush any assembly debris from the new gearbox before returning to normal service intervals.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8036 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-1.9.webp\" alt=\"L-25J D\u00fcngerstreuer-Getriebe 1-1,9\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-1.9.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25J-Fertilizer-Spreader-Gearbox-1-1.9-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Common Troubleshooting for the L-25A Fertilizer Spreader Gearbox<\/h2>\n<div>\n<h3>Excessive Noise or Whining<\/h3>\n<p>Abnormal noise from the gearbox during PTO operation typically indicates insufficient oil level, degraded lubricant, incorrect oil grade, or worn bearings and gears. First, shut down the PTO immediately and check the\u00a0fertilizer spreader gearbox oil level. If the oil level is correct, drain and refill with fresh 80W-90 gear oil. If noise persists after oil service, the gearbox should be removed for internal inspection, as continued operation with worn gears or dry bearings will cause rapid and irreversible internal damage.<\/p>\n<\/div>\n<div>\n<h3>Oil Leaks Around Shaft Seals<\/h3>\n<p>Oil seepage at the input or output shaft bores indicates worn or damaged lip seals. Seal deterioration is accelerated by heat cycles, chemical exposure from fertilizer residue, or operation with the wrong oil viscosity. Replace both shaft seals as a pair whenever one is found to be leaking, as both will have experienced identical service conditions. Overfilling the gearbox beyond the 0.35-litre maximum can also cause seal bypass; always verify the correct fill level after any oil service on these\u00a0fertilizer spreader gearbox parts.<\/p>\n<\/div>\n<div>\n<h3>Vibration at the Spreader Disc<\/h3>\n<p>Excessive vibration transmitted from the gearbox to the spreading disc assembly often originates from a loose or worn output shaft coupling, a bent disc, or worn output shaft bearings. Shut down the PTO and manually check the disc for radial play on the output shaft. A loose disc retaining nut is the most common cause and requires only re-torqueing to specification. If bearing play is detected at the output shaft, the gearbox requires bearing replacement. Operating with significant vibration will rapidly accelerate wear across all internal\u00a0fertilizer spreader gearbox parts.<\/p>\n<\/div>\n<div>\n<h3>Getriebe\u00fcberhitzung<\/h3>\n<p>A gearbox housing that becomes unusually hot to the touch during normal operation indicates lubrication failure, an overloaded condition, or incorrect oil viscosity. Immediately shut down the PTO and allow the unit to cool before investigating. Check the oil level and condition first. If the oil is correct but the unit overheats at rated load, the gearbox may be operating beyond its 5.2 kW \/ 7 HP power limit. Contact CMN Transmission to discuss whether a higher-rated\u00a0agricultural gearbox for fertilizer spreader\u00a0is required for your application.<\/p>\n<\/div>\n<div>\n<h3>Irregular or Uneven Spreading Pattern<\/h3>\n<p>Wenn der D\u00fcngerstreuer trotz korrekter Maschineneinstellungen ungleichm\u00e4\u00dfige Streumuster erzeugt, kann dies an einer ungleichm\u00e4\u00dfigen Scheibendrehzahl liegen. Ursache hierf\u00fcr k\u00f6nnen Besch\u00e4digungen der Zahnr\u00e4der oder verschlissene Lager sein, die zu Drehzahlschwankungen im Getriebe f\u00fchren. Auch verschlissene Streuschaufeln, verstopfte Schaufelkan\u00e4le oder ein falsches \u00dcbersetzungsverh\u00e4ltnis des D\u00fcngerstreuergetriebes f\u00fcr die erforderliche Streugeschwindigkeit k\u00f6nnen die Ursache sein. Pr\u00fcfen Sie, ob Getriebemodell und \u00dcbersetzungsverh\u00e4ltnis den Anforderungen Ihres Streuers entsprechen, und untersuchen Sie die Streuschaufeln auf Verschlei\u00df oder D\u00fcngerablagerungen, bevor Sie das Getriebe als defekt einstufen.<\/p>\n<\/div>\n<div>\n<h3>PTO Slip or Input Shaft Wear<\/h3>\n<p>Schlupf oder zeitweise unterbrochene Kraft\u00fcbertragung am Nebenabtriebsanschluss (PTO) wird \u00fcblicherweise durch verschlissene 1-3\/8\u2033-Verzahnungen an der Getriebeeingangswelle oder am Nebenabtriebsjoch verursacht. Der Verschlei\u00df der Verzahnung ist fortschreitend und entsteht typischerweise durch unzureichende \u00dcberlappung des Nebenabtriebsstrangs, zu gro\u00dfe Winkelabweichungen des Nebenabtriebs oder Sto\u00dfbelastungen durch \u00dcberlastung. Pr\u00fcfen Sie die Eingangsverzahnung, indem Sie die Nebenabtriebswelle ausbauen und auf abgerundete oder abgebrochene Z\u00e4hne achten. Wird nur das Getriebe ausgetauscht, wenn auch die Verzahnung des Nebenabtriebsjochs verschlissen ist, f\u00fchrt dies innerhalb kurzer Betriebszeit zu einem erneuten Ausfall der neuen Getriebeeingangswelle.<\/p>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8092 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-1.webp\" alt=\"Anwendungen f\u00fcr Getriebe von D\u00fcngerstreuern\" width=\"1200\" height=\"900\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-1.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-1-980x735.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-1-480x360.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>D\u00fcngerstreuer-Getriebe und Zapfwellenantriebswelle<\/h2>\n<p>Die Verbindung zwischen dem Getriebe des D\u00fcngerstreuers und der Zapfwelle ist die entscheidende mechanische Schnittstelle jedes traktorbetriebenen Streusystems. Die Zapfwelle (PTO) \u00fcbertr\u00e4gt die Rotationsenergie des Traktormotors auf den Streuer. Bei landwirtschaftlichen Traktoren arbeitet die Zapfwelle typischerweise mit 540 U\/min und ist \u00fcber eine Keilwellenkupplung mit dem Getriebeeingang verbunden. Diese Kupplung muss hinsichtlich Profil, Durchmesser und Anzahl der Verzahnungen auf den Getriebeeingang abgestimmt sein, um eine sichere und spielfreie Kraft\u00fcbertragung zu gew\u00e4hrleisten. Beim L-25A ist der Eingang f\u00fcr eine 1-3\/8\u2033-Sechszahnwelle gem\u00e4\u00df ISO 500 ausgelegt und somit mit den meisten weltweit eingesetzten Kompakt- und Mittelklasse-Traktoren kompatibel.<\/p>\n<p>Die Zapfwellenbaugruppe besteht aus einem Innen- und einem Au\u00dfenrohr, die teleskopartig verschoben werden k\u00f6nnen, um den unterschiedlichen Abstand zwischen Traktor und Anbauger\u00e4t beim Lenken und bei der Fahrt auf dem Feld auszugleichen. Kreuzgelenke an beiden Enden der Zapfwelle gleichen die Winkelabweichung zwischen dem Zapfwellenausgang des Traktors und dem Getriebeeingang aus. Diese Gelenke m\u00fcssen innerhalb des vom Hersteller vorgegebenen maximalen Betriebswinkels betrieben werden, um Vibrationen, Ger\u00e4usche und vorzeitigen Verschlei\u00df zu vermeiden. Bei Verwendung des Getriebes L-25A an einer korrekt dimensionierten D\u00fcngerstreuerkupplung sollte der Winkel des Zapfwellenantriebsstrangs \u00fcber den gesamten Bewegungsbereich der Traktorzugstange unter 15 Grad bleiben.<\/p>\n<p>The fertilizer distributor gearbox serves three critical functions that the PTO shaft alone cannot perform. First, it increases rotational speed from 540 RPM PTO input to approximately 1,501 RPM at the output, matching the disc speed required for effective fertilizer throw and lateral distribution. Second, it redirects the rotational axis where required by the spreader geometry, allowing vertical disc mounting on horizontally-arranged PTO input systems. Third, it multiplies torque to provide the rotational force needed to overcome the inertia of heavy spreading discs loaded with granular material, especially during startup and when material flow rates are high.<\/p>\n<p>Die Sicherheitsintegration zwischen Zapfwelle und Getriebe ist ebenso wichtig. Jeder Zapfwellenantrieb muss \u00fcber eine Rutschkupplung oder einen Scherbolzen-\u00dcberlastschutz verf\u00fcgen, der zwischen dem Traktorausgang und dem Getriebeeingang angeordnet ist. Diese Vorrichtung ist so kalibriert, dass sie das Drehmoment reduziert, wenn die Streuscheibe blockiert oder auf eine Blockade st\u00f6\u00dft. Dadurch wird verhindert, dass die Impulslast \u00fcber das Getriebe zur\u00fcck in den Traktorantriebsstrang \u00fcbertragen wird. Ohne diesen Schutz k\u00f6nnte eine blockierte Scheibe Zahnr\u00e4der besch\u00e4digen, die Eingangswelle abscheren oder das Traktorgetriebe zerst\u00f6ren. CMN Transmission empfiehlt, bei der Bestellung von Ersatz- oder Neuinstallations-Zapfwellenantrieben passende Zapfwellen mit voreingestellten Rutschkupplungen zu verwenden, die auf die Arbeitslast von 5,2 kW \/ 31 Nm des L-25A ausgelegt sind.<\/p>\n<p>The PTO shaft guard or safety shield is a legal requirement in most countries and is an essential safety component that prevents operator contact with the rotating shaft. Both the PTO shaft guard and the gearbox input shield must be correctly fitted and secured at all times during PTO operation. Damaged or missing guards should be replaced before the machine is returned to service. CMN Transmission can supply compatible PTO shaft assemblies with CE-certified safety guards that are dimensionally matched to the L-25A gearbox input connection.<\/p>\n<p>When sourcing a replacement PTO shaft for use with this agricultural gearbox for fertilizer spreader, the key specification parameters include overall collapsed and extended length (to suit the tractor-to-spreader hitch distance), the input and output yoke profiles (to match both the tractor PTO and the gearbox input splines), and the power rating of the slip clutch (which should match the maximum power rating of the L-25A, being 5.2 kW at 540 RPM). Pairing the correct PTO shaft with the L-25A gearbox ensures that the entire drivetrain from tractor to spreading disc operates as a matched, reliable system that delivers consistent spreading performance season after season.<\/p>\n<p>Operators seeking both a replacement fertilizer spreader gearbox and a compatible PTO shaft assembly are encouraged to contact CMN Transmission directly. Our technical team can supply matched gearbox and PTO shaft packages configured to your specific tractor model, spreader type, and hitch geometry, eliminating the risk of dimensional or power-rating mismatches that could compromise both performance and equipment longevity in the field.<\/p>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 50%;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8073 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5.webp\" alt=\"D\u00fcngerstreuer-Getriebe\" width=\"1000\" height=\"1000\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5.webp 1000w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5-980x980.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1000px, 100vw\" \/><\/td>\n<td style=\"width: 50%;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-343 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft.webp\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1000px, 100vw\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft.webp 1000w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft-980x980.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft-480x480.webp 480w\" alt=\"Zapfwelle\" width=\"1000\" height=\"1000\" \/><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>How to Select the Right Fertilizer Spreader Gearbox<\/h2>\n<p>1. Load Capacity and Power Rating<br \/>\nThe gearbox must be rated for the full combined mechanical load of the fertilizer material weight, disc inertia, and spreading resistance under your specific operating conditions. The L-25A is rated at 5.2 kW and 31 N\u00b7m, which is appropriate for single-disc compact spreaders. For twin-disc or large-capacity hopper spreaders, evaluate whether a higher power rating from the CMN Transmission fertilizer spreader gearboxes range is required before ordering.<\/p>\n<p>2. Gear Ratio and Spreading Speed<br \/>\nThe fertilizer spreader gearbox ratio directly controls the disc rotational speed and therefore the lateral throw distance and spreading width. The 1:2.78 ratio of the L-25A is matched to standard 540 RPM PTO applications where a moderate disc speed is required for granular fertilizers across typical arable field widths. If your spreading prescription requires a different disc speed, CMN Transmission can advise on alternative ratio models from our agricultural gearbox catalogue.<\/p>\n<p>3. Material and Build Durability<br \/>\nFertilizer spreading environments are exceptionally corrosive due to the hygroscopic and reactive nature of common fertilizer compounds. Aluminium housings, as used in the L-25A, provide excellent corrosion resistance at lower weight than cast iron. Internal gears and shafts should be case-hardened alloy steel with precision-ground tooth profiles. Verify that any fertilizer spreader gearbox under consideration uses sealed bearings and chemical-resistant shaft seals before purchasing.<\/p>\n<p>4. Dimensional Compatibility<br \/>\nFor replacement applications, ensure that the replacement gearbox matches OEM mounting dimensions, flange bolt pattern, input spline size, and output shaft diameter exactly. The L-25A Comer replacement from CMN Transmission is dimensionally matched to the original Comer gearbox, ensuring bolt-on installation without frame modification. For new spreader builds, share your frame drawing and shaft requirements with our fertilizer spreader suppliers team for a confirmed fitment check.<\/p>\n<p>5. Maintenance Accessibility<br \/>\nA gearbox that is difficult to service in the field will accumulate deferred maintenance, shortening service life and increasing total ownership cost. The L-25A features accessible oil fill and drain plugs, a simple oil-bath lubrication system requiring only periodic oil changes, and modular seal and bearing components that are widely available from CMN Transmission. When comparing fertilizer spreader gearbox manufacturers, always evaluate the availability and cost of wear parts before making a purchasing decision.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8021 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91.webp\" alt=\"T-281A D\u00fcngerstreuer-Getriebe 1-2,91\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Warum sollten Sie sich f\u00fcr die D\u00fcngerstreuergetriebe von CMN Transmission entscheiden?<\/h2>\n<p>Korea CMN Transmission Co., Ltd. was established in 2000 and is headquartered in Sandan-o, Danwon-gu, Ansan-si, Gyeonggi-do, Republic of Korea.

Dieses CMN Transmission L-25A ist als pr\u00e4ziser Ersatz f\u00fcr das Comer L-25A Getriebe konstruiert. Das Schraubenmuster des Montageflansches, die Verzahnung des Eingangswellenantriebs (1-3\/8\u2033 Sechszahn), der Durchmesser der Ausgangswelle (22 mm) und die Geh\u00e4useabmessungen entsprechen dem Originalteil von Comer. In den meisten F\u00e4llen gen\u00fcgt es, das alte Getriebe abzuschrauben und das neue ohne Rahmenmodifikation oder Adapterplatten zu montieren. Sollten Sie eine abweichende Comer-Variante besitzen, teilen Sie bitte vor der Bestellung die Seriennummer Ihrer Maschine unserem technischen Team zur Best\u00e4tigung mit.<\/p>\n<p><strong>Q: What type and quantity of oil does the L-25A fertilizer spreader gearbox require?<\/strong><br \/>\nA: The L-25A requires SAE 80W-90 mineral gear oil, with a maximum fill capacity of 0.35 litres. All gearboxes are supplied dry (without oil), so you must fill to the correct level before the first run. To check the fertilizer spreader gearbox oil level, remove the level check plug on the housing side and verify oil is present at the plug bore level. The first oil change should be carried out at 50-70 operating hours to purge any assembly debris, and subsequently every 500 hours or at least once per year. Using incorrect oil viscosity or contaminated oil will accelerate internal wear.<\/p>\n<p><strong>Q: What does the 1:2.78 fertilizer spreader gearbox ratio mean in practice?<\/strong><br \/>\nA: A 1:2.78 fertilizer spreader gearbox ratio means that for every single revolution of the PTO input shaft, the gearbox output shaft completes 2.78 revolutions. At the standard 540 RPM PTO speed, the output shaft therefore rotates at approximately 1,501 RPM. This step-up ratio is specifically chosen for single-disc fertilizer spreaders that require a higher rotational speed at the disc than the PTO can directly provide, ensuring adequate centrifugal force for lateral throw of granular fertilizer. If you need a different disc speed for your specific spreading application, CMN Transmission offers alternative ratio models.<\/p>\n<p><strong>Q: What is the maximum power and torque rating of this agricultural gearbox?<\/strong><br \/>\nA: Das Getriebe L-25A ist f\u00fcr eine maximale Eingangs- und Ausgangsleistung von 5,2 kW (7 PS) bei 540 U\/min und ein maximales Drehmoment von 31 Nm ausgelegt. Diese Werte definieren die oberen Grenzwerte f\u00fcr den Dauerbetrieb des Getriebes und d\u00fcrfen im Normalbetrieb nicht \u00fcberschritten werden. F\u00fcr Anwendungen mit h\u00f6herem Leistungsbedarf, wie z. B. schwere Doppelscheibenstreuer oder Gro\u00dfbeh\u00e4ltersysteme, empfehlen wir die gr\u00f6\u00dferen Landwirtschaftsgetriebe von CMN Transmission f\u00fcr D\u00fcngerstreuer. Kontaktieren Sie unser technisches Team mit Ihren Leistungs- und Drehmomentanforderungen f\u00fcr eine Produktempfehlung.<\/p>\n<p><strong>Q: Can I use this gearbox with fertilizers other than granular NPK products?<\/strong><br \/>\nA: Yes. The L-25A is compatible with a wide range of granular materials including NPK blends, single-nutrient fertilizers (urea, ammonium nitrate, muriate of potash), lime prills, pelleted compost, and granulated micronutrient products. For liquid fertilizer systems, a different spreader disc and agitator configuration is required, but the gearbox itself is fully compatible with liquid application spreader builds where the disc or agitator loads remain within the 5.2 kW \/ 31 N\u00b7m rating. Always rinse spreader disc and hopper components with fresh water after applying hygroscopic or reactive fertilizers to prevent corrosive residue accumulation.<\/p>\n<p><strong>Q: What is the weight and housing material of the L-25A fertilizer spreader gearbox?<\/strong><br \/>\nA: The L-25A weighs 4.1 kg and features a die-cast aluminium alloy housing. The aluminium construction provides several practical advantages over cast iron alternatives: it is significantly lighter, which simplifies installation and reduces total spreader weight, improving tractor stability and reducing soil compaction on sensitive ground. Aluminium also provides inherent resistance to the corrosive effects of fertilizer chemicals, particularly ammonium-based compounds and potassium chloride. The housing exterior is further protected by an epoxy finish coating to prevent surface corrosion from prolonged fertilizer exposure.<\/p>\n<p><strong>Q: What fertilizer spreader gearbox parts are available as spares from CMN Transmission?<\/strong><br \/>\nA: CMN Transmission stocks a comprehensive range of fertilizer spreader gearbox parts for the L-25A, including input and output shaft oil seals, deep-groove ball bearings, bevel gear sets, housing gaskets, and mounting hardware. Genuine CMN replacement parts are machined to the same specifications as the original components and are the only parts recommended for warranty-approved repairs. To order spare parts, please provide the gearbox model (L-25A), the specific part required, and your quantity. Our parts team can also assist with identifying worn components from photographs or part number references.<\/p>\n<p><strong>Q: Is a warranty provided with the CMN Transmission L-25A fertilizer gearbox?<\/strong><br \/>\nA: Yes, all CMN Transmission agricultural gearboxes are covered by our standard manufacturing warranty against defects in materials and workmanship. The warranty requires that the gearbox be installed, filled with the correct oil, and operated within its rated power and torque limits. Damage resulting from overload, incorrect oil, contaminated lubrication, improper installation, or operation without PTO driveline overload protection is not covered under warranty. Please retain your purchase documentation and contact our after-sales team with any warranty claim enquiries, supported by photographs of the defect and your operating details.<\/p>\n<p><strong>Q: Can CMN Transmission supply custom fertilizer spreader gearboxes to different ratios or shaft configurations?<\/strong><br \/>\nA: Yes. CMN Transmission maintains a catalogue of nearly one thousand agricultural gearbox specifications and can also develop custom agricultural gearbox solutions for OEM manufacturers and specialty machine builders. Whether you require a different fertilizer spreader gearbox ratio, alternative input or output shaft dimensions, a modified mounting flange, or a left-hand rotation variant, our engineering team can review your requirements and advise on standard variants or custom development options. Minimum order quantities apply for fully custom designs. Contact us with your technical specification and application details for a quotation.<\/p>\n<p><strong>Q: What tractor PTO speed is the L-25A fertilizer spreader gearbox compatible with?<\/strong><br \/>\nA: The L-25A is rated and specified for use at 540 RPM PTO input speed, which is the standard low-speed PTO setting on the overwhelming majority of compact to mid-size agricultural tractors used worldwide. It is not designed for use at 1000 RPM PTO speed, which would exceed the rated input speed and would cause significant overspeed of the output shaft. If you need a gearbox for a 1000 RPM PTO application, please contact CMN Transmission to identify a suitable alternative from our broader fertilizer spreader gearboxes product range. We can also advise on intermediate RPM requirements.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8018 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.84-1.webp\" alt=\"T-281A D\u00fcngerstreuer-Getriebe 1,84-1\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.84-1.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1.84-1-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Kundenrezensionen<\/h2>\n<p><strong>James Whitfield, Wheat Farming, United Kingdom<\/strong><br \/>\n\u201eIch nutze das L-25A-Getriebe jetzt seit etwa acht Monaten an meinem Amazone ZA-M Doppelscheibenstreuer und es l\u00e4uft einwandfrei. Wir haben im letzten Herbst rund 80 Hektar Weizen mit NPK 23-0-10 ged\u00fcngt, und die Scheibendrehzahl blieb dabei konstant. Es ist federleicht im Vergleich zum urspr\u00fcnglichen Comer-Getriebe, das wir ersetzt haben. Der erste \u00d6lwechsel erfolgte wie empfohlen nach 60 Betriebsstunden und war sauber. Ich bin wirklich sehr zufrieden damit.\u201c<\/p>\n<p><strong>Fernando Albuquerque, Soybean and Corn Farming, Brazil<\/strong><br \/>\n\u201eWir haben vier dieser Getriebe f\u00fcr unsere Flotte von Kompaktstreuern bestellt, die wir auf Soja- und Maisfarmen im Bundesstaat Mato Grosso einsetzen. Das \u00dcbersetzungsverh\u00e4ltnis von 1:2,78 war perfekt f\u00fcr unsere Bed\u00fcrfnisse. Alles wurde gut verpackt innerhalb von etwa 12 Tagen aus Korea geliefert. Die Installation war einfach, da das Lochmuster perfekt zu unseren Streuerrahmen passte. Nach drei Monaten und rund 150 Betriebsstunden mit dem am st\u00e4rksten beanspruchten Ger\u00e4t gab es keinerlei Probleme. Gutes Preis-Leistungs-Verh\u00e4ltnis.\u201c<\/p>\n<p><strong>Trevor MacAllister, Crop Farming, Australia<\/strong><br \/>\n\u201eMein originales Comer-Getriebe hat mitten in der Saison, genau als ich es am dringendsten brauchte, den Geist aufgegeben. Ich habe CMN Transmission online gefunden und dieses Ersatzgetriebe L-25A bestellt. Der Kundenservice war unglaublich hilfsbereit, hat meine technischen Fragen noch am selben Tag beantwortet und die Ma\u00dfe vor der Bestellung best\u00e4tigt. Das Getriebe kam in weniger als zwei Wochen im l\u00e4ndlichen Queensland an und lie\u00df sich ohne jegliche Anpassungen problemlos einbauen. Es hat die Regenzeit bisher einwandfrei \u00fcberstanden.\u201c<\/p>\n<p><strong>Klaus Hoffmeister, Farm Equipment, Germany<\/strong><br \/>\n\u201eWir haben dieses Getriebe als Ersatz f\u00fcr unser altes Comer-Getriebe am D\u00fcngerstreuer bestellt. Die Qualit\u00e4t ist sehr gut; das Aluminiumgeh\u00e4use ist leicht und sauber verarbeitet. Einziger kleiner Kritikpunkt: Die Verpackung h\u00e4tte etwas stabiler sein k\u00f6nnen. Technisch einwandfreie Spezifikationen, passt perfekt und l\u00e4uft leise. Wir werden wieder bei CMN Transmission bestellen.\u201c<\/p>\n<p><strong>Michael Dupont, Lawn and Turf Management, Canada<\/strong><br \/>\n\u201eIch leite einen Golfplatz und zwei Sportanlagen. F\u00fcr die Rasend\u00fcngung verwenden wir einen kleinen Scheibenstreuer. Das Originalgetriebe war nach etwa f\u00fcnf Saisons intensiver Nutzung verschlissen, was ehrlich gesagt eine beachtliche Leistung ist. Das Ersatzgetriebe von CMN ist leiser als das Original und hat das gleiche \u00dcbersetzungsverh\u00e4ltnis, sodass wir keine Streuereinstellungen \u00e4ndern mussten. Wir verwenden das empfohlene Castrol-Getriebe\u00f6l 80W-90. Ich bin sehr zufrieden mit dem Kauf.\u201c<\/p>\n<p><strong>Antoine Moreau, Vineyard Maintenance, France<\/strong><br \/>\n\u201eWir setzen in unseren Weinbergen im Burgund D\u00fcngerstreuer ein, und die Getriebe werden an den H\u00e4ngen stark beansprucht. Wir haben drei dieser L-25A-Einheiten als Ersatzteile f\u00fcr unsere Werkstatt bestellt, und eine ist bereits eingebaut. Sie arbeitet ger\u00e4uschlos, ist dicht, und das Aluminiumgeh\u00e4use scheint unsere Kaliumsulfat-Anwendungen problemlos zu \u00fcberstehen, ohne zu korrodieren. Die mitgelieferte technische Dokumentation ist sehr ausf\u00fchrlich. Der Versand nach Frankreich dauerte etwa 10 Werktage, was akzeptabel ist.\u201c<\/p>\n<p><strong>Roberto Perez Vega, Agricultural Machinery, Mexico<\/strong><br \/>\n\u201eWir haben dieses Getriebe als Ersatzteil f\u00fcr unseren D\u00fcngerstreuer in Guadalajara gekauft. Wir nutzen es seit vier Monaten intensiv f\u00fcr Mais und Sorghum und es funktioniert einwandfrei. Das Verkaufsteam hat uns vor dem Kauf geholfen, die Kompatibilit\u00e4t mit unserem Streuermodell zu best\u00e4tigen, was wir sehr zu sch\u00e4tzen wissen. Der Preis ist im Vergleich zu anderen europ\u00e4ischen Marken sehr wettbewerbsf\u00e4hig. Wir k\u00f6nnen es uneingeschr\u00e4nkt empfehlen.\u201c<\/p>\n<p><strong>Rajiv Choudhary, Crop Farming, India<\/strong><br \/>\n\u201eUnser Unternehmen hat zehn L-25A-Getriebe bestellt, die alle den korrekten Spezifikationen entsprachen. Sie passen auch perfekt in unseren D\u00fcngerstreuer. Das Team von CMN Transmission hat all unsere technischen Fragen sehr schnell beantwortet. Die Qualit\u00e4t ist sehr gut und der Preis angemessen. Wir planen, in der n\u00e4chsten Saison weitere zu bestellen.\u201c<\/p>\n<p><strong>Carlos Mendez Bianchi, Soy and Wheat Farming, Argentina<\/strong><br \/>\n\u201eWir haben dieses Getriebe als Notfallersatz bestellt, nachdem unser Hauptgetriebe w\u00e4hrend der Pampasgras-Saison ausgefallen war. CMN Transmission bearbeitete die Bestellung noch am selben Tag und organisierte den Luftfrachtversand, sodass wir es innerhalb von sechs Tagen erhielten. Wir haben es am Abend der Lieferung eingebaut und konnten am n\u00e4chsten Morgen wieder streuen. Es hat nun \u00fcber 80 Betriebsstunden absolviert und l\u00e4uft einwandfrei. Ich kann weder das Produkt noch den Service bem\u00e4ngeln. Wir werden von nun an zwei dieser Getriebe als Ersatzteile vorr\u00e4tig halten.\u201c<\/p>","protected":false},"excerpt":{"rendered":"<p>The L-25A Fertilizer Spreader Gearbox Ratio 1:2.78, a direct replacement for the Comer L-25A Gearbox, is also widely known as a fertilizer distributor gearbox.
