Built for Real Farm Work
These Massey Ferguson 100 and 200 series tractors with their traditional transmission patterns are workhorses found on farms everywhere. Whether you’re using your 135 for loader work, running your 165 through hay fields, or pulling implements with your 240, reliable gear selection is essential for getting work done efficiently.
Made to Last
This selector rail lock is manufactured to handle the constant stress of gear changes under load. The precise tolerances ensure it holds those selector rails exactly where they need to be, even when you’re shifting between ranges while working through tough field conditions.
Good to Know
This is an internal transmission component that requires transmission disassembly for installation – typically a job for an experienced mechanic. While you’ve got the transmission apart, it’s smart to inspect other selector components and replace any that show wear since they work together as a system.
