When your tractor won't engage PTO or you're hearing grinding noises when trying to power up your implements, the problem might be deeper than you think. The PTO pinion is the critical gear inside your transmission that connects engine power to your PTO shaft. If it's worn or damaged, your bush hog, baler, or mower isn't getting the reliable power transfer it needs to do the job right. What You're Getting Precision-machined gear with 98.2mm tooth span for exact fit in your transmission Built specifically for 12-speed syncro non-shuttle transmissions Hardened steel construction that handles full engine torque without stripping Direct replacement that restores proper PTO engagement and power transfer Built for Real Farm Work This pinion fits the transmissions in your Massey Ferguson workhorses from the 200 series up through the 600 series, plus the heavy-duty 1000 series models. These are the tractors that handle everything from hay operations and cultivation to heavy loader work where reliable PTO power makes the difference between getting the job done and sitting broke down in the field. Made to Last Transmission gears take tremendous loads, especially in PTO applications where implements create shock loads and constant engagement cycles. This pinion is manufactured to OEM specifications with proper heat treatment and tooth geometry to mesh smoothly with your transmission's internal components and provide years of reliable service. Installation Notes This is an internal transmission component that requires splitting the tractor and removing the transmission housing to access. It's definitely a job for someone comfortable with major transmission work or best left to a qualified shop. Make sure to inspect all related PTO components while you've got the transmission apart.

When you're in the middle of clutch work or transmission service, finding transmission oil where it shouldn't be is never good news. A leaking input housing seal lets precious hydraulic fluid escape while letting dirt and moisture find their way into your transmission. This complete seal kit stops those leaks at the source and keeps your Massey Ferguson's transmission protected from contamination that can cause expensive internal damage down the road. What You're Getting Complete set of seals specifically for the 42S input housing design Quality materials that handle transmission pressure and temperature swings Direct replacement seals that match original equipment specifications Professional-grade gaskets and O-rings that maintain proper sealing under field conditions Built for Real Farm Work This seal kit fits both Massey Ferguson 300 series and 4200 series tractors that use the 42S input housing configuration. These versatile machines handle everything from cultivation and planting to loader work and hay production. The 300 series tractors are popular for their reliability in row crop farming, while the 4200 series provides the extra horsepower needed for heavier implements and more demanding field operations. Made to Last Farm transmissions work hard under constantly changing loads and conditions. These seals are manufactured from compounds that resist breakdown from hydraulic fluids and temperature extremes. They're designed to maintain their sealing properties through thousands of hours of operation, protecting your transmission investment. Good to Know This is typically transmission-out work that's best done when you're already splitting the tractor for clutch service or other major repairs. While you've got everything apart, it's the perfect time to replace these seals rather than risk contaminating new clutch components later. Always clean the housing surfaces thoroughly and check for scoring that could prevent proper sealing.
