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

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

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

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

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

\"Przek\u0142adnia<\/p>\n

How to Correctly Replace the L-25A Gearbox<\/h2>\n

1. Safety Preparation and Machine Isolation
\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

2. Spu\u015b\u0107 stary olej ze skrzyni bieg\u00f3w
\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

3. Remove the Spreading Disc or Output Coupling
\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

4. Unbolt and Remove the Old Gearbox
\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

5. Inspect PTO Driveline Components
\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

6. Install and Torque the New L-25A Gearbox
\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

7. Fill with Fresh 80W-90 Gear Oil
\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

8. Reconnect PTO and Run-In Check
\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

\"Przek\u0142adnia<\/p>\n

Common Troubleshooting for the L-25A Fertilizer Spreader Gearbox<\/h2>\n
\n

Excessive Noise or Whining<\/h3>\n

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

\n

Oil Leaks Around Shaft Seals<\/h3>\n

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

\n

Vibration at the Spreader Disc<\/h3>\n

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

\n

Przegrzanie skrzyni bieg\u00f3w<\/h3>\n

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

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

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

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

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\n\n\n

How to Select the Right Fertilizer Spreader Gearbox<\/h2>\n

1. Load Capacity and Power Rating
\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

2. Gear Ratio and Spreading Speed
\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

3. Material and Build Durability
\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

4. Dimensional Compatibility
\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

5. Maintenance Accessibility
\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

Q: What type and quantity of oil does the L-25A fertilizer spreader gearbox require?<\/strong>
\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

Q: What does the 1:2.78 fertilizer spreader gearbox ratio mean in practice?<\/strong>
\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

Q: What is the maximum power and torque rating of this agricultural gearbox?<\/strong>
\nA: Maksymalna moc wej\u015bciowa i wyj\u015bciowa przek\u0142adni L-25A wynosi 5,2 kW (7 KM) przy 540 obr.\/min, a maksymalny moment obrotowy na wyj\u015bciu 31 Nm.

Q: Can I use this gearbox with fertilizers other than granular NPK products?<\/strong>
\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

Q: What is the weight and housing material of the L-25A fertilizer spreader gearbox?<\/strong>
\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

Q: What fertilizer spreader gearbox parts are available as spares from CMN Transmission?<\/strong>
\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

Q: Is a warranty provided with the CMN Transmission L-25A fertilizer gearbox?<\/strong>
\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

Q: Can CMN Transmission supply custom fertilizer spreader gearboxes to different ratios or shaft configurations?<\/strong>
\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

Q: What tractor PTO speed is the L-25A fertilizer spreader gearbox compatible with?<\/strong>
\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

Jako\u015b\u0107 jest bardzo dobra; aluminiowa obudowa jest lekka i starannie wyko\u0144czona. Jedyny drobny minus: opakowanie mog\u0142oby by\u0107 nieco solidniejsze. Technicznie absolutnie poprawne, pasuje idealnie i pracuje cicho. Z\u0142o\u017cymy zam\u00f3wienie ponownie w CMN Transmission.\u201d<\/p>\n

\n\u201eZarz\u0105dzam polem golfowym i dwoma kompleksami sportowymi, a do nawo\u017cenia trawnik\u00f3w u\u017cywamy ma\u0142ego rozsiewacza tarczowego. Oryginalna skrzynia bieg\u00f3w zu\u017cy\u0142a si\u0119 po oko\u0142o pi\u0119ciu sezonach intensywnego u\u017cytkowania, co szczerze m\u00f3wi\u0105c, jest ca\u0142kiem niez\u0142e. Ten zamiennik CMN jest cichszy ni\u017c orygina\u0142 i ma takie samo prze\u0142o\u017cenie, wi\u0119c nie musieli\u015bmy zmienia\u0107 ustawie\u0144 rozsiewacza. Stosujemy olej przek\u0142adniowy Castrol 80W-90, zgodnie z zaleceniami. Jestem bardzo zadowolony z zakupu.\u201d<\/p>\n

\n\u201eU\u017cywamy rozsiewaczy nawozu w naszych winnicach w Burgundii, a skrzynie bieg\u00f3w s\u0105 mocno eksploatowane na zboczach. Zam\u00f3wili\u015bmy trzy sztuki tych rozsiewaczy L-25A jako cz\u0119\u015bci zamienne do warsztatu i jedna zosta\u0142a ju\u017c zamontowana. Zero ha\u0142asu, zero wyciek\u00f3w, a aluminiowa obudowa zdaje si\u0119 bez problemu radzi\u0107 sobie z naszymi aplikacjami siarczanu potasu bez \u015bladu korozji. Do\u0142\u0105czona dokumentacja techniczna jest bardzo kompletna. Wysy\u0142ka do Francji zaj\u0119\u0142a oko\u0142o 10 dni roboczych, co jest akceptowalne.\u201d<\/p>\n

\n\u201eKupili\u015bmy t\u0119 skrzyni\u0119 bieg\u00f3w jako cz\u0119\u015b\u0107 zamienn\u0105 do naszego rozsiewacza nawoz\u00f3w w Guadalajarze. U\u017cywamy jej intensywnie do zbioru kukurydzy i sorgo od czterech miesi\u0119cy i dzia\u0142a idealnie. Zesp\u00f3\u0142 sprzeda\u017cy pom\u00f3g\u0142 nam potwierdzi\u0107 kompatybilno\u015b\u0107 z naszym modelem rozsiewacza przed zakupem, co jest dla nas bardzo cenne. Cena jest bardzo konkurencyjna w por\u00f3wnaniu z innymi europejskimi markami. Zdecydowanie polecamy.\u201d<\/p>\n

\n\u201eNasza firma zam\u00f3wi\u0142a 10 sztuk przek\u0142adni L-25A i wszystkie by\u0142y zgodne ze specyfikacj\u0105. Idealnie pasowa\u0142y r\u00f3wnie\u017c do naszego rozsiewacza nawoz\u00f3w. Zesp\u00f3\u0142 CMN Transmission bardzo szybko odpowiedzia\u0142 na wszystkie nasze pytania techniczne. Jako\u015b\u0107 jest bardzo dobra, a cena r\u00f3wnie\u017c rozs\u0105dna. Zamierzamy zam\u00f3wi\u0107 wi\u0119cej w przysz\u0142ym sezonie\u201d.<\/p>\n

\nZam\u00f3wi\u0142em to jako awaryjn\u0105 cz\u0119\u015b\u0107 zamienn\u0105, gdy nasza g\u0142\u00f3wna przek\u0142adnia uleg\u0142a awarii w sezonie rozrzucania pampas\u00f3w. Firma CMN Transmission przetworzy\u0142a zam\u00f3wienie tego samego dnia i zorganizowa\u0142a transport lotniczy, dzi\u0119ki czemu otrzymali\u015bmy je w ci\u0105gu sze\u015bciu dni. Zamontowali\u015bmy je w noc dostawy i rano mogli\u015bmy kontynuowa\u0107 rozrzucanie. Przepracowa\u0142o ju\u017c ponad 80 godzin i dzia\u0142a idealnie. Nie mam \u017cadnych zastrze\u017ce\u0144 do produktu ani serwisu. Od teraz b\u0119d\u0119 zatrzymywa\u0107 dwa takie urz\u0105dzenia jako zapasowe na miejscu.<\/p>","protected":false},"excerpt":{"rendered":"

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. It is an essential component of agricultural machinery, specifically engineered for soil preparation, crop treatment, and fertilizer spreading. Positioned at the center of the machine, it transmits power from the tractor\u2019s power take-off (PTO) to the spinning discs or augers that evenly distribute fertilizer across the fields. Engineered for durability and reliability, this agricultural gearbox ensures consistent power transmission to meet varying operational demands throughout the growing season.<\/p>","protected":false},"featured_media":8006,"comment_status":"open","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[309],"product_tag":[316,315,311,317,318,319,310],"class_list":{"0":"post-8111","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-fertilizer-spreader-gearbox","7":"product_tag-fertiliser-spreader-gearbox","8":"product_tag-fertilizer-distributor-gearbox","9":"product_tag-fertilizer-spreader-gearbox","10":"product_tag-fertilizer-spreader-gearbox-for-sale","11":"product_tag-fertilizer-spreader-gearbox-manufacturers","12":"product_tag-fertilizer-spreader-gearbox-suppliers","13":"product_tag-gearbox-for-fertilizer-spreader","15":"first","16":"instock","17":"shipping-taxable","18":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/product\/8111","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/comments?post=8111"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/media\/8006"}],"wp:attachment":[{"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/media?parent=8111"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/product_brand?post=8111"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/product_cat?post=8111"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/product_tag?post=8111"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
