When your Massey Ferguson’s transmission starts grinding gears, slipping out of gear, or refuses to shift smoothly, the counter shaft might be the culprit. This precision-machined counter shaft is the heart of your 6-speed transmission, transferring power between the main shaft and output gears. Without a good counter shaft, you’re looking at expensive transmission work or worse—being stuck in the field when there’s work to do.
What You’re Getting
- Precise 15-tooth configuration that meshes perfectly with transmission gears for smooth power transfer
- 17-spline design ensures solid connection to transmission components without slippage under load
- Bottom main shaft position controls lower gear ratios where torque demands are highest
- Quality construction built to handle the constant stress of field work and varying loads
- Direct replacement part—no modifications needed for proper fit
Built for Real Farm Work
This counter shaft fits a wide range of Massey Ferguson tractors from the compact 35 series up through the larger 700 and 800 series machines. These tractors handle everything from hay operations and livestock work to row crop farming and loader duties. The 6-speed transmission gives you the gear range needed for both precision fieldwork and road transport, making this shaft critical for versatile tractor operation.
Made to Last
Counter shafts take tremendous loads during operation, especially when you’re pulling heavy implements or working in tough conditions. This shaft is manufactured to OEM specifications with proper heat treatment and surface finish to resist wear from constant gear mesh contact. The precise tooth profile and spline dimensions ensure smooth operation and long service life.
Installation Notes
Counter shaft replacement requires transmission disassembly, so this isn’t a quick roadside fix. It’s typically part of a larger transmission rebuild or repair. While you’ve got the transmission apart, it’s smart to inspect all related gears, bearings, and synchronizers. This is also the perfect time to replace transmission seals and gaskets to prevent future leaks.
