Description

When you’re trying to get up a steep hill with a heavy load or need that slow, steady power for precision work, first gear is what gets you through. If your tractor won’t pull like it used to or you’re hearing grinding noises when shifting into low range, this replacement first gear could be exactly what you need. With 44 precisely-cut teeth, this gear restores the pulling power that makes your Massey Ferguson the reliable workhorse it was meant to be.

What You’re Getting

44-tooth design engineered for maximum torque multiplication in first gear
Precision-machined teeth that mesh smoothly with other transmission gears
Heavy-duty construction built to handle the high loads of first gear operation
Direct replacement for worn or damaged gears in both 6-speed and 8-speed transmissions
Quality steel construction with proper heat treatment for long service life

Built for Real Farm Work

This gear fits an impressive range of Massey Ferguson tractors from the compact 35 series utility tractors up through the powerful 4300 series row-crop machines. Whether you’re running a small farm with a trusty MF 135 or operating a larger operation with 4000 series tractors, this gear handles the same demanding work – from pulling heavy implements through tough soil to climbing steep hills with loaded wagons.

Made to Last

First gear takes more abuse than any other gear in your transmission because it’s where all that engine torque gets multiplied for maximum pulling power. This replacement gear features the same tooth profile and heat treatment as the original, so it’ll mesh properly with your existing gears and stand up to years of heavy pulling without premature wear or tooth damage.

Installation Notes

This is a major transmission repair that requires splitting the tractor to access the gear case. Most operators tackle this work during winter downtime or combine it with other major transmission service. While you’re in there, it’s smart to inspect all the other gears and synchros – replacing just one worn gear in a damaged set won’t solve your problems long-term.
