6. Roadside & Specialty Mowing
\nIn applications such as maintaining roadsides, drainage ditches, airport buffer strips, and conservation headlands, a controlled, clean cut in irregular or ecologically sensitive areas is essential. The smooth power transmission of this PTO drive shaft for discbine prevents the vibration and speed variation that can cause uneven cutting especially important where a consistent cut height is required for appearance, water flow management, or wildlife habitat preservation. The Double CV joint’s high articulation tolerance also makes this shaft suited to tractors working on slopes or uneven ground typical of these specialty mowing contexts.<\/p>\n

Asennusvaiheet<\/h2>\n
1. Turvallisuusvalmistelut: Irrota ja pys\u00e4yt\u00e4 ajoneuvo
\nEnnen kuin aloitat mit\u00e4\u00e4n t\u00f6it\u00e4 traktorin voimanottoakselij\u00e4rjestelm\u00e4n parissa, sammuta traktorin moottori kokonaan, kytke seisontajarru ja odota, ett\u00e4 kaikki py\u00f6riv\u00e4t osat ovat pys\u00e4htyneet kokonaan. Irrota virta-avain ja laita se taskuusi. Aseta py\u00f6r\u00e4kiilat lautas\u00e4keen kuljetuspy\u00f6rien alle. N\u00e4m\u00e4 vaiheet ovat pakollisia turvaohjeita aina ty\u00f6skennelt\u00e4ess\u00e4 voimanottoakselin osien kanssa moottorik\u00e4ytt\u00f6isiss\u00e4 maatalouskoneissa, eik\u00e4 niit\u00e4 pid\u00e4 koskaan lyhent\u00e4\u00e4, vaikka kiireinen sadonkorjuuaikataulu olisi eritt\u00e4in kiireinen.<\/p>\n
2. Irrota vanha akseli ja suojuskokoonpano
\nIrrota voimanottoakselin suojuksen kiinnitysketjut tai -pidikkeet sek\u00e4 traktorin ett\u00e4 lautasakselin p\u00e4\u00e4st\u00e4. Liu'uta suojuksen kiinnityskaulus taaksep\u00e4in paljastaaksesi traktorin puoleisen haarukkap\u00e4\u00e4n lukituskauluksen. Paina traktorin puoleisen haarukkap\u00e4\u00e4n pikalukituspainiketta (tai, jos kyseess\u00e4 on kitkakaulustyyppi, vapauta lukituskaulus) ja liu'uta akseli taaksep\u00e4in irti traktorin voimanottoakselin akselitapista. Tue akselia, jotta se ei putoa vetoaisalle tai maahan. Vapauta sitten ty\u00f6koneen puoleisen haarukkap\u00e4\u00e4n lukitustappi ja irrota akseli kokonaan. Huomioi CV-nivelen kellojen suunta ennen irrottamista, jotta uuden akselin asentaminen on helpompaa.<\/p>\n
3. Tarkista ja puhdista uraliitokset
\nBefore fitting the new PTO drive shaft, clean the tractor PTO stub (1.375\u201121 or 1.750\u201120) and the discbine gearbox input (1.5″ x 23 spline) with a wire brush and solvent to remove corrosion, old grease, and contamination. Inspect both stubs for spline wear, chipping, or impact damage. Damaged tractor or implement splines should be addressed before fitting a new shaft, as worn splines accelerate yoke wear and can cause the new shaft to disengage unexpectedly during field operation. Apply a thin film of high-load grease to both stubs before coupling.<\/p>\n
4. Mittaa ja aseta oikea akselin pituus
\nKytke lautas\u00e4e traktoriin ja laske vetoaisa normaaliin ty\u00f6asentoonsa. Mittaa et\u00e4isyys traktorin voimanottoakselin akselin tapin ja lautas\u00e4teen vaihteiston sis\u00e4\u00e4ntuloakselin tapin v\u00e4lisest\u00e4 p\u00e4\u00e4st\u00e4. Vertaa t\u00e4t\u00e4 mittaa uuden voimanottoakselin putken kokoon taitettuun ja pidennettyyn pituusalueeseen. Yleiss\u00e4\u00e4nt\u00f6n\u00e4 on, ett\u00e4 akseli tulee asettaa siten, ett\u00e4 se toimii suunnilleen teleskooppiosan puoliv\u00e4liss\u00e4 normaalik\u00e4yt\u00f6ss\u00e4 ja ett\u00e4 v\u00e4hint\u00e4\u00e4n 1\/3 sis\u00e4putkesta pysyy kytkettyn\u00e4 t\u00e4yteen pidennettyn\u00e4. S\u00e4\u00e4d\u00e4 voimanottoakselin pituutta liu'uttamalla teleskooppiosaa oikean p\u00e4\u00e4llekk\u00e4isyyden saavuttamiseksi. Merkitse p\u00e4\u00e4llekk\u00e4isyyden pituus maalitussilla my\u00f6hemp\u00e4\u00e4 tarvetta varten.<\/p>\n
5. Kytke akseli traktoriin ja ty\u00f6koneeseen
\nAloita ty\u00f6koneen (lautasnivelen) p\u00e4\u00e4st\u00e4: kohdista Case IH:n lautasnivelen voimanottoakselin ty\u00f6koneen puoleinen haarukka vaihteiston tuloakselin tapin kanssa ja liu'uta sit\u00e4 eteenp\u00e4in, kunnes lukitusmekanismi napsahtaa. Nyk\u00e4ise akselia taaksep\u00e4in varmistaaksesi t\u00e4yden kytkenn\u00e4n. Kytke sitten traktorin puoleinen CV-nivelen haarukka traktorin voimanottoakselin tappiin. Ved\u00e4 kaulus sis\u00e4\u00e4n, kohdista naaraspuolinen ura traktorin tappiin kuuluvan urospuolisen uran kanssa ja ty\u00f6nn\u00e4 tiukasti eteenp\u00e4in, kunnes lukitusmekanismi napsahtaa uraan. Varmista pit\u00e4v\u00e4 kytkeytyminen vet\u00e4m\u00e4ll\u00e4 CV-nivelen kelloa taaksep\u00e4in lukitusasentoa vasten.<\/p>\n
6. Asenna ja kiinnit\u00e4 nivelakselin suojus
\nSlide the PTO shaft guard sections over the assembled shaft, connecting the guard’s retaining chains to the tractor drawbar or hitch pin and to the discbine chassis anchor point. The chains should allow the guard to remain stationary when the shaft rotates but should not be so loose that the guard droops into contact with the ground when the machine is raised for transport. Check that the guard shell does not contact the rotating shaft or yoke assemblies at any point through the full articulation range of the tractor-discbine combination.<\/p>\n
7. Voitelu- ja sis\u00e4\u00e4najotarkistus
\nLevit\u00e4 suurtuottoista litium-EP2-rasvaa kaikkiin CV-nivelen kellokoteloiden voitelunippoihin, teleskooppiputkeen ja kaikkiin n\u00e4kyviin j\u00e4\u00e4viin uraliit\u00e4nt\u00f6ihin. K\u00e4ynnist\u00e4 traktori, kytke voimanulosotto alhaisella moottorin kierrosluvulla ja tarkkaile akselia v\u00e4hint\u00e4\u00e4n yhden t\u00e4yden nivelsyklin ajan (t\u00e4ysi vasen ja oikea lukitus) varmistaaksesi, ettei t\u00e4rin\u00e4\u00e4, suojusten kosketusongelmia tai ep\u00e4normaaleja \u00e4\u00e4ni\u00e4 esiinny. Lis\u00e4\u00e4 nopeutta v\u00e4hitellen t\u00e4yteen 1 000 rpm:n k\u00e4ytt\u00f6nopeuteen ja anna moottorin l\u00e4mmet\u00e4 lyhyesti ennen peltoty\u00f6n aloittamista. Tarkista kaikki voitelukohdat, suojusten ketjut ja haarukan lukitusmekanismit uudelleen ensimm\u00e4isen peltok\u00e4ytt\u00f6tunnin j\u00e4lkeen.<\/p>\n

<\/p>\n
How to Choose the Right PTO Shaft for Disc Mower<\/h2>\n
Step 1: Confirm Your Tractor’s PTO Spline Standard
\nThe most critical dimension when ordering any tractor PTO shaft is the tractor output spline profile. For the Case IH 8312 application, the tractor stub is typically either a 1-3\/8″ 21-spline (1.375\u201121) or a 1-3\/4″ 20-spline (1.750\u201120). Check your tractor’s operator manual or measure the stub diameter and count the spline teeth directly to confirm which standard applies. Ordering the wrong spline profile is the most common sourcing error for PTO shaft parts and will result in a shaft that cannot couple to the tractor.<\/p>\n
Vaihe 2: Tarkista ty\u00f6koneen sy\u00f6tt\u00f6ura
\nFor the Case IH 8312 discbine, the standard implement input spline is 1.5″ x 23 splines. However, if the discbine’s gearbox input has been previously replaced or if you are fitting a replacement CV half-shaft for a different implement, confirm the implement-side PTO shaft adapter or input stub spline before ordering. CMN Transmission can supply the complete shaft, the implement-side CV half only, or the tractor-side CV half as individual PTO shaft parts. Specify which configuration you require when placing your order.<\/p>\n
Vaihe 3: Mittaa tarvittava nivelakselin pituus
\nMittaa traktorin voimanottoakselin keskipisteiden v\u00e4linen et\u00e4isyys vaihteiston levyakselin sis\u00e4\u00e4ntuloakselista normaalissa ty\u00f6asennossa. Toimita t\u00e4m\u00e4 mittaus CMN Transmissionille varmistaaksesi, ett\u00e4 voimanottoakselin vakiomitat ovat oikeat kokoonpanoosi. Jos et\u00e4isyys on vakiomittaisen kokoontaitetun ja ojennetun akselin alueen ulkopuolella, CMN Transmission voi valmistaa mittatilausty\u00f6n\u00e4 oikean pituisen voimanottoakselin. V\u00e4\u00e4r\u00e4 akselin pituus on toiseksi yleisin sovitusongelma ja voi johtaa akselin pohjaanmenoon (aiheuttaen iskuvaurioita) tai repe\u00e4miseen kokonaan ojennettuna.<\/p>\n
Vaihe 4: Arvioi ylikuormitussuojauksesi tarpeet
\nConsider whether your operating conditions require additional overload protection beyond what the shaft’s structural design provides. Farms with known stone contamination in fields, rocky ground conditions, or operations that frequently cut downed fence posts and debris benefit from a slip clutch PTO shaft or shear bolt PTO shaft configuration. A PTO shaft with slip clutch will disengage under shock loads, protecting both the discbine gearbox and the tractor PTO output from impact damage. Discuss the torque rating and clutch slip threshold appropriate for your tractor’s horsepower with CMN Transmission’s technical team.<\/p>\n
Vaihe 5: Valitse kokonaisen akselin ja puoliakselin vaihtoehdoista
\nJos alkuper\u00e4isest\u00e4 Weasler-akselista on vain toinen p\u00e4\u00e4 pett\u00e4nyt, esimerkiksi jos vain traktorin puoleinen CV-nivel on kulunut, kun taas ty\u00f6koneen puoleinen CV-puolikas on edelleen k\u00e4ytt\u00f6kelpoinen, CMN Transmission tarjoaa yksitt\u00e4isi\u00e4 CV-puoliakselikokoonpanoja kustannustehokkaana vaihtoehtona koko voimansiirtoakselin vaihtamiselle. Tarkasta olemassa olevan akselin molemmat p\u00e4\u00e4t huolellisesti: jos voimanottoakselin U-nivelen risteykset, laakerikupit, keskityskuula tai haarukan rei\u00e4t osoittavat kulumista vain toisella puolella, puoliakselin vaihto voi olla taloudellisin vaihtoehto. Jos kulumista n\u00e4kyy molemmissa p\u00e4iss\u00e4 tai jos voimanottoakselin putkisto on vaurioitunut, tilaa koko akselikokoonpano.<\/p>\n

<\/p>\n
Yleinen vianm\u00e4\u00e4ritys<\/h2>\n
1. T\u00e4rin\u00e4 k\u00e4yt\u00f6n aikana
\nVibration in the PTO drive shaft system is most commonly caused by worn or damaged PTO shaft u joint crosses, excessive spline wear allowing radial play in the yokes, or a bent shaft tube. Check all CV joint bearing cups for pitting or roughness by rotating the shaft by hand. Inspect the PTO shaft tubing for straightness by rolling it on a flat surface. Vibration can also result from the shaft operating at an excessive angle. Ensure the tractor’s drawbar height and the discbine’s tongue jack height are adjusted to minimize the static operating angle of the shaft.<\/p>\n
2. Akseli irtoaa traktorin akselitapista
\nIf the tractor PTO shaft disconnects from the tractor stub during operation, the most likely cause is a worn or damaged locking collar or release button on the tractor-side yoke. The retaining groove on the tractor PTO stub may also be worn, preventing the locking pin from seating fully. Inspect the collar spring for fatigue or fracture. In some cases, the shaft may be operating at the limit of its extension range, causing the yoke to cam off the stub. Check the shaft’s installed length and adjust the telescoping overlap if necessary.<\/p>\n
3. Teleskooppiputki tarttuu kiinni tai tarttuu kiinni
\nNivelakselin putken jumittunut tai j\u00e4ykk\u00e4 teleskooppiliit\u00e4nt\u00e4 johtuu voitelun puutteesta, kosteuden p\u00e4\u00e4syst\u00e4 sis\u00e4\u00e4n, joka johtaa korroosioon, tai profiilin uraan tunkeutuvasta sorasta ja kasvij\u00e4tteist\u00e4. Irrota akseli ja ty\u00f6nn\u00e4 sis\u00e4putki kokonaan ulos. Puhdista molemmat putkiprofiilit huolellisesti liuottimella ja j\u00e4yk\u00e4ll\u00e4 harjalla, poista kaikki ruoste hiomakankaalla ja levit\u00e4 runsas kerros molybdeeni- tai EP2-litiumrasvaa ennen kokoamista. Aseta voiteluv\u00e4li v\u00e4hint\u00e4\u00e4n; putken liit\u00e4nt\u00e4 on voideltava 8 ty\u00f6tunnin v\u00e4lein hein\u00e4nkorjuun aikana.<\/p>\n
4. Koputus- tai napsahdus\u00e4\u00e4ni alhaisella nopeudella
\nRytminen kolina- tai naksahdus\u00e4\u00e4ni, joka on erityisen havaittavissa voimanottoakselin kytkenn\u00e4n yhteydess\u00e4 tai alhaisella ajonopeudella, viittaa tyypillisesti haarukan tai traktorin akselin nastan ura-akselin kulumiseen, joka iskee jokaisella kierroksella, kuluneeseen CV-nivelen keskityspalloon tai -holkkiin kaksois-CV-kokoonpanossa tai vaurioituneeseen laakerikuppiin voimanottoakselin ristiniveless\u00e4. Erota n\u00e4m\u00e4 eritt\u00e4m\u00e4ll\u00e4, kumpi akselin p\u00e4\u00e4 tuottaa \u00e4\u00e4nen. Keskityselementin kuluminen aiheuttaa naksahduksen jokaisella CV-nivelen nivelsyklill\u00e4, kun taas ura-akselin kuluminen aiheuttaa naksahduksen yleens\u00e4 vain v\u00e4\u00e4nt\u00f6momentin suunnanvaihdon yhteydess\u00e4.<\/p>\n
5. Py\u00f6riv\u00e4\u00e4n akseliin koskettava suojus
\nJos nivelakselin suojus koskettaa py\u00f6rivi\u00e4 osia, yleisimm\u00e4t syyt ovat liian lyhyet pid\u00e4tysketjut (jotka vet\u00e4v\u00e4t suojusta kosketukseen), suojuksen p\u00e4\u00e4tysuppilot, jotka ovat ep\u00e4muodostuneet tai v\u00e4\u00e4rin kohdistetut, tai sis\u00e4\u00e4np\u00e4in haljennut ja painunut suojakuori. Ketjujen tulisi antaa suojuksen roikkua vapaasti est\u00e4en samalla py\u00f6rimisen ja maahan kosketuksen. Vaihda kaikki haljenneet tai ep\u00e4muodostuneet suojaosat v\u00e4litt\u00f6m\u00e4sti. Viallinen nivelakselin suojus on turvallisuusriski, jota ei saa k\u00e4ytt\u00e4\u00e4 ennen korjausta. CMN Transmission toimittaa varaosia suojuksen osina yksitt\u00e4isin\u00e4 nivelakselin osina.<\/p>\n
6. Discbine-vaihteisto k\u00e4y kuumana
\nOverheating of the discbine gearbox is not always caused by the gearbox itself. If the PTO shaft for disc mower is operating at an excessive angle due to an incorrect drawbar height setting, the CV joints transmit increased radial load into the gearbox input shaft bearings, accelerating their wear and generating additional heat. Check that the shaft operating angle does not exceed the rated CV joint capacity. Also verify that the gearbox oil level is correct and that the PTO speed matches the implement’s rated input operating a 1,000 RPM 1000 rpm PTO shaft rated implement at 540 RPM or vice versa causes severe power imbalance and gearbox damage.<\/p>\n

<\/p>\n
Lautasleikkurin voimanottoakseli ja vaihteisto<\/h2>\n
The disc mower PTO shaft is the mechanical link between the tractor’s power output and the disc mower’s internal drive system. On a pull-type drawbar machine like the Case IH 8312, the PTO driveline shaft must accommodate the lateral, vertical, and fore-aft movement of the articulating hitch while transmitting torque continuously at 1,000 RPM. The Double Constant Velocity design used in this CAT 6 shaft ensures that despite these angular and positional changes, the rotational speed delivered to the disc mower gearbox input remains smooth and constant. Without a functioning tractor PTO drive shaft, the entire disc mower cutterbar and conditioning system is immobilized regardless of the condition of the gearbox, knives, or conditioning rolls.<\/p>\n
Lautasniittokoneen vaihteisto (jota kutsutaan my\u00f6s leikkuupalkin p\u00e4\u00e4vaihteistoksi tai keskusvaihteistoksi) on moniulotteisen kartio- ja lieri\u00f6hammaspy\u00f6r\u00e4kokoonpano, joka on asennettu leikkuupalkin palkin keskelle. Sen teht\u00e4v\u00e4n\u00e4 on vastaanottaa py\u00f6rimisvoima lautasniittokoneen voimanottoakselilta ja jakaa t\u00e4m\u00e4 teho samanaikaisesti kaikille lautaster\u00e4kokoonpanoille leikkuupalkin koko ty\u00f6leveydelle useiden yhdist\u00e4vien hammaspy\u00f6rien tai yhteisen, leikkuupalkin palkin alla kulkevan vetoakselin kautta. Case IH 8312 -mallissa vaihteisto k\u00e4ytt\u00e4\u00e4 my\u00f6s akselia, joka antaa voiman leikkuupalkin yl\u00e4puolella oleville kumimurskainteloille. Vaihteisto sis\u00e4lt\u00e4\u00e4 vaihteisto\u00f6ljy\u00e4, jonka taso on pidett\u00e4v\u00e4 oikeana ja joka on vaihdettava valmistajan m\u00e4\u00e4ritt\u00e4min v\u00e4lein. \u00d6ljynpuutteessa oleva lautasniittokoneen vaihteisto ylikuumenee, sy\u00f6vytt\u00e4\u00e4 hammaspy\u00f6r\u00e4pintojaan ja lopulta juuttuu katastrofaalisesti tuhoten kalliin valun ja kaikki sis\u00e4iset hammaspy\u00f6r\u00e4t.<\/p>\n
The PTO drive shaft for discbine and the disc mower gearbox are functionally inseparable: the quality and condition of the PTO shaft directly affects the longevity of the gearbox, and vice versa. A worn or vibrating agricultural PTO shaft imposes radial and axial loads on the gearbox input shaft bearings far beyond their design rating, accelerating bearing and seal wear. Conversely, a gearbox with internal gear damage or misaligned shafts increases the torque ripple transmitted back into the PTO shaft, accelerating U-joint and CV joint wear. CMN Transmission supplies both precision disc mower PTO shafts and a full range of disc mower gearbox assemblies and replacement parts, allowing operators and dealers to source both components from a single, certified supplier and ensuring full dimensional and torque compatibility between the two. Whether you need a replacement of Weasler PTO shaft or a rebuilt disc mower gearbox for the Case IH 8312, CMN Transmission’s technical team can advise on the correct specification for your exact machine serial number range.<\/p>\n

Usein kysytyt kysymykset<\/h2>\n
K: Onko t\u00e4m\u00e4 nivelakseli suora korvaaja Case IH 8312:n Weasler 55N -akselille?<\/strong>
\nV: Kyll\u00e4. T\u00e4m\u00e4 Weaslerin nivelakselin vaihto-osa on suunniteltu saman 55N-sarjan Double CV -spesifikaation mukaisesti, ja siin\u00e4 on 80 asteen traktorin puoleinen CV-nivel ja 50 asteen ty\u00f6koneen puoleinen CV-nivel. Traktorin ja ty\u00f6koneen haarukkaprofiilit vastaavat alkuper\u00e4ist\u00e4 kokoonpanoa, eik\u00e4 Case IH 8312 -levykuormaimen suoraasennus vaadi sovittimia tai muutoksia.<\/p>\nK: Mit\u00e4 voimanottoakselin kokoja 8312-malliin on saatavilla, ja mist\u00e4 tied\u00e4n, mink\u00e4 kokoisia tarvitsen?<\/strong>
\nA: There are four configurations: (1) complete double CV shaft with 1.375-21 tractor and 1.5″x23 implement splines; (2) implement-side 55N 50\u00b0 CV half with 1.5″x23 spline only; (3) tractor-side 55N 80\u00b0 CV half with 1.375-21 spline; and (4) tractor-side 55N 80\u00b0 CV half with 1.750-20 spline. To choose correctly, identify your tractor’s PTO stub spline (measure the diameter and count spline teeth) and determine whether you need a complete shaft or a single CV half replacement. CMN Transmission’s pre-sales team can confirm the correct PTO shaft sizes for your machine upon request.<\/p>\nK: Onko kyseess\u00e4 540 RPM vai 1000 RPM voimanottoakseli, ja onko sill\u00e4 v\u00e4li\u00e4?<\/strong>
\nA: The Case IH 8312 is rated for a 1000 RPM PTO shaft input, and this CMN Transmission shaft is specified accordingly. Operating a 1,000 RPM-rated implement on a 540 RPM tractor PTO output will result in severely under-powered performance and possible cutterbar stalling. Operating it above its rated speed risks overloading the gearbox and shaft assembly. Always confirm your tractor’s PTO output speed matches the implement’s rated input before coupling any 540 PTO shaft or 1000 PTO shaft to a new implement.<\/p>\nQ: Can I get a custom PTO shaft length if the standard dimensions don’t fit my setup?<\/strong>
\nV: Kyll\u00e4. CMN Transmission on erikoistunut mittatilausty\u00f6n\u00e4 tehtyyn voimanottoakselien valmistukseen. Jos traktorisi lautasgeometria on standardin mukaisen kokoontaitetun ja pidennettyn \u200b\u200bpituusalueen ulkopuolella esimerkiksi ep\u00e4standardin vetoaisan jatkeen tai vetokoukun muutoksen vuoksi, toimita CMN:lle tarvittava kokoontaitetun ja pidennettyn \u200b\u200bpituuden sek\u00e4 ura-akselin tiedot, niin tekninen tiimi valmistaa mittatilausty\u00f6n\u00e4 tehdyn akselin tarkkojen voimanottoakselin mittojen mukaisesti. Mittatilausty\u00f6n\u00e4 tehdyn kokoonpanon mittapiirustukset toimitetaan vahvistusta varten ennen tuotannon aloittamista.<\/p>\nK: Kuinka usein minun pit\u00e4isi voidella Case IH 8312 -traktorini nivelakseli?<\/strong>
\nA: T\u00e4m\u00e4n maatalousk\u00e4ytt\u00f6\u00f6n tarkoitetun nivelakselin kaikki voitelunipat, mukaan lukien CV-nivelen kellokotelon nipat ja teleskooppisen nivelakselin putken nippa, on voideltava 8 k\u00e4ytt\u00f6tunnin v\u00e4lein aktiivisen niittojakson aikana. K\u00e4yt\u00e4 Case IH 8312 -k\u00e4ytt\u00f6oppaassa m\u00e4\u00e4ritetty\u00e4 kuormituslitium-EP2- tai molybdeenirasvaa. Voitele kaikki kohdat huolellisesti ennen k\u00e4ytt\u00f6kautta ja tarkista nivelen U-nivelen laakerikupit karheuden ja v\u00e4lyksen varalta. Voitele kauden j\u00e4lkeen ennen varastointia kosteuden poistamiseksi kaikilta sis\u00e4isilt\u00e4 laakeripinnoista.<\/p>\nK: Mik\u00e4 aiheuttaa niittokoneeni nivelakselin U-nivelen ennenaikaisen kulumisen?<\/strong>
\nA: The primary causes of premature PTO shaft u joint and CV joint wear in disc mower applications are: (1) insufficient or incorrect grease type leading to metal-on-metal contact; (2) operating the shaft at excessive angles beyond the CV joint’s rated capacity; (3) shock loading from striking rocks or debris without slip clutch protection; (4) vibration induced by worn tractor PTO output bearings transmitting imbalance loads into the driveshaft; and (5) contaminated grease containing grit or crop chaff abrading the needle bearing surfaces. Address all five factors to maximize PTO shaft parts service life.<\/p>\nK: Onko t\u00e4ss\u00e4 nivelakselissa suojus, ja t\u00e4ytt\u00e4\u00e4k\u00f6 se CE-turvallisuusvaatimukset?<\/strong>
\nV: Kyll\u00e4, t\u00e4yspitk\u00e4 nivelakselin suojus sis\u00e4ltyy vakiona. Suojuksen rakenne t\u00e4ytt\u00e4\u00e4 CE-konedirektiivin vaatimukset ja on suunniteltu pysym\u00e4\u00e4n paikallaan akselin py\u00f6riess\u00e4 peitt\u00e4en kaikki py\u00f6riv\u00e4t osat, mukaan lukien vetonivelen kotelot, nivelakselin putket ja v\u00e4lilaakerialueen. CE-merkint\u00e4 on erityisen t\u00e4rke\u00e4\u00e4 maanviljelij\u00f6ille ja urakoitsijoille Euroopan unionin maissa ja muissa laink\u00e4ytt\u00f6alueissa, joissa vakuutus-, ty\u00f6terveys- ja ty\u00f6turvallisuusm\u00e4\u00e4r\u00e4ykset tai konedirektiivin noudattamisvelvoitteet edellytt\u00e4v\u00e4t CE-merkittyj\u00e4 py\u00f6rivi\u00e4 osia.<\/p>\nK: Voinko tilata vain nivelakselin haarukkap\u00e4\u00e4n vai yksitt\u00e4isi\u00e4 nivelakselin osia koko akselin sijaan?<\/strong>
\nA: Yes. CMN Transmission supplies individual PTO shaft parts including CV half-shafts (tractor or implement side), PTO shaft yoke assemblies, replacement PTO shaft u joint crosses and bearing cup kits, guard sections, and PTO shaft adapter elements. If your existing shaft tube is intact but one CV bell has failed, ordering a replacement CV half is significantly more economical than replacing the complete PTO driveline shaft. Describe the failed component in detail to CMN’s technical team, including dimensions and part markings, for the most accurate replacement recommendation.<\/p>\nK: Mink\u00e4 muiden traktorimerkkien ja -mallien kanssa t\u00e4m\u00e4 nivelakseli on yhteensopiva Case IH:n lis\u00e4ksi?<\/strong>
\nA: The tractor PTO shaft yoke configurations available 1.375-21 (1-3\/8″ 21-spline) and 1.750-20 (1-3\/4″ 20-spline) are the two most common PTO stub standards used globally, meaning this shaft is dimensionally compatible with the PTO output of most major tractor brands including John Deere, New Holland, Massey Ferguson, Fendt, Deutz-Fahr, Claas, Kubota, and others that produce tractors with 1,000 RPM PTO outputs in the relevant horsepower range. Confirm the tractor stub spline before ordering. The implement side (1.5″ x 23 spline) is specific to the Case IH 8312 discbine gearbox input standard.<\/p>\n![\"Nivelakseli](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-Case-IH-Disc-Mower-16.webp\")

Asiakasarvostelut<\/h2>\n
Marcus, maatilan johtaja, Yhdysvallat<\/strong>
\n“We run a Case IH 8312 on our 240-acre operation in Missouri, mainly alfalfa and orchardgrass. Been through two Weasler shafts in the last seven years, so when the last one let go mid-season, I started shopping around. Found CMN Transmission, ordered the complete 55N 80×50 Double CV shaft with the 1.375 21 tractor spline. Arrived in just under two weeks, packaged really well. Fit was dead on, the splines dropped straight in, locking collar clicked home clean. Now three cutting seasons in on this shaft and honestly it feels better than the OEM. No vibration, no noise, the guard is still intact. Good value.”<\/p>\nDerek, varaosakauppias, Kanada<\/strong>
\n“I manage a small agricultural parts dealership in Ontario. We started stocking CMN Transmission’s disc mower PTO shafts about two years ago after a customer brought in a broken Weasler CV half for an 8312. Could not source the OEM part quickly, so we tried CMN. The shaft dimensions matched the spec sheet exactly. Since then we have ordered maybe 30 units in various configurations, the 1.750 20 tractor side halves move fastest for us. Customers have not come back with complaints. Communication with CMN’s sales team is prompt, and they will send dimensional drawings on request. That matters a lot when you are dealing with a fitment critical part like a tractor PTO drive shaft.”<\/p>\nCraig, Grazier, Australia<\/strong>
\n“Had a full season disaster two summers ago when the CV bell on my Weasler shaft cracked near the end of silage cutting. Local dealer wanted nearly double what CMN quoted for the same 55N 50-degree CV half on the implement side. Ordered from CMN, arrived in New South Wales within 12 days, which surprised me, honestly, given the distance. The weld quality on the yoke looked clean, the guard funnel fit snugly, and the spline count on the 1.5×23 side was spot on. It has been through one full silage season and two dry hay cuts since. Holding up well. Recommend.”<\/p>\nJames, siemenviljelij\u00e4, Uusi-Seelanti<\/strong>
\n“We use an 8312 for our ryegrass seed crops in the Canterbury Plains. The shaft we ordered was the complete 55N double CV, 1.375 21 tractor side. Shipping took about 16 days to New Zealand which is acceptable. Fitment was fine, no issues with the splines or collar. The main thing I would say is the guard is a bit lighter than the Weasler original, but it is not causing any issues in practice. The shaft itself runs smoothly at 1000 PTO, no vibration. We have done maybe 400 acres on it over two seasons. Price difference from OEM was significant, saved enough to cover the shipping twice over.”<\/p>\nStefan, urakoitsija, Saksa<\/strong>
\n“I operate a contract mowing business in Bavaria and use several Case IH machines, including an 8312. When the drive shaft failed at the end of last year, we ordered from CMN Transmission. The service was excellent, with quick email responses in German and English, and technical drawings sent by email within 24 hours. The shaft arrived in 10 days and fit exactly. Quality corresponds to what I am accustomed to from European brands, but at a significantly lower price. We will use CMN for further orders.”<\/p>\nPhil, maatalousmekaanikko, Yhdistynyt kuningaskunta<\/strong>
\n“I am a farm machinery mechanic in Lincolnshire. We service a lot of Case IH kits, including 8312 discbines. Started sourcing PTO shafts from CMN about 18 months ago when a customer needed a replacement fast and the OEM part was on a three week backorder. CMN had it in stock. The ISO and CE certifications were important for my customer. They are a large commercial arable and grass farm that requires CE-marked components for insurance and compliance. Everything checked out. I have since fitted five of these shafts across different machines and not had a single comeback. Solid product.”<\/p>\nAntonio, karjankasvattaja, Espanja<\/strong>
\n“We purchased the complete PTO shaft for our Case IH 8312, the double CV 55N model with tractor spline 1.375 21. We placed the order online and it took about 14 days to arrive in Castilla y Le\u00f3n. The fit was perfect, without the need for adapters. We have already completed two mowing seasons without problems. The price was considerably lower than the official Case IH replacement. Pre sale communication was very good. They responded to all our technical questions quickly and accurately.”<\/p>\nRodrigo, osuuskunnan johtaja, Brasilia<\/strong>
\n“Our cooperative manages about 800 hectares of mixed forage in the Mato Grosso do Sul region of Brazil. We run two Case IH 8312 discbines during the main hay harvest. One shaft needed full replacement after one of the CV bell housings cracked, probably from a rock strike. We reached out to CMN Transmission, they confirmed the correct part within a day, and the shaft arrived at our logistics agent in S\u00e3o Paulo in about 11 days. From there it took another 3 days to reach our farm. Fit was exact. The build quality, especially the yoke welds, looks better than what we had on the machine originally. We pre ordered a spare as well.”<\/p>\nLaurent, varaosakauppias, Ranska<\/strong>
\n“I am a dealer of agricultural spare parts in the Auvergne Rh\u00f4ne Alpes region. I ordered once from CMN Transmission to test the quality before offering their products to my customers. The double CV PTO shaft for Case IH 8312 that I received was impeccable, dimensions compliant, clean welds, universal joint well greased from the factory. I then ordered 8 other units for my stock. Delivery times are acceptable for the distance. The quality-price ratio is excellent compared to European brands. I recommend it without hesitation for farmers and professionals of agricultural machinery.”<\/p>","protected":false},"excerpt":{"rendered":"CMN Transmissionin Case IH discbine 8312 -lautasniittokoneen voimansiirtoakseli on tarkasti suunniteltu, tehtaalta suoraan valmistettu korvaaja alkuper\u00e4iselle 55N Weasler -yksik\u00f6lle.
