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.
