Description
When you’re shifting gears and feeling grinding or noticing your tractor won’t move smoothly through its range, chances are your transmission shaft has worn out. This back-end output shaft connects your transmission to the gearbox, transferring all that engine power to your wheels. If it’s damaged or worn, you’re looking at lost time, lost power, and potentially expensive transmission damage if you keep pushing it.
What You’re Getting
- Precision-machined shaft that fits exactly like the original equipment
- Hardened steel construction built to handle the torque these tractors put out
- Proper dimensions ensure smooth power transfer from transmission to gearbox
- Direct replacement part that restores reliable shifting and drive engagement
Built for Real Farm Work
This shaft fits the reliable MF 135, 240, and 690 models that are workhorses on farms everywhere. Whether you’re using your 135 for hay operations, running your 240 through cultivating work, or putting your 690 to heavy pulling tasks, this is the critical link that gets power from your transmission to your drive wheels. These tractors handle everything from loader work to field preparation, and they need a transmission shaft that won’t quit when the work gets tough.
Made to Last
Transmission shafts take incredible stress from constant rotation, torque loads, and the vibration of hard farm work. This replacement shaft is built with proper metallurgy and heat treatment to handle years of operation without wearing prematurely or developing the play that causes transmission problems.
Installation Notes
This is a transmission-out job that requires splitting the tractor between the transmission and rear end. It’s not a quick fix, but replacing a worn shaft now prevents much more expensive transmission damage down the road. Make sure to check all related seals and gaskets while you’ve got things apart.
