Description
When you’re pushing your Massey hard with high-demand implements like big rotary cutters or round balers, your PTO shaft better be up to the job. This 21-spline 1000 RPM shaft delivers the smooth, reliable power transfer you need for those big jobs that demand everything your tractor’s got. No slipping, no vibration—just solid power from your PTO to the implement.
What You’re Getting
- 21-spline design gives you more contact area for handling high torque loads without slippage
- Bolt-on mounting system keeps everything locked tight under the stress of 1000 RPM operation
- Precision machining eliminates the vibration that hammers your equipment over time
- Direct replacement that installs with the bolt and locator pin you need
Built for Real Farm Work
This shaft powers the heavy-duty implements that keep your operation productive—those big mowers that eat through thick growth, round balers working all day, and forage equipment that can’t afford to slow down. Whether you’re cutting hay all season or running a high-capacity mower conditioner, this shaft handles the power demands of modern 1000 RPM implements.
Made to Last
The 21-spline configuration spreads the load across more contact points, so you don’t get the wear and stress concentration that kills shafts early. Quality construction means this shaft will keep transferring power season after season, even when you’re running at full throttle with heavy implements.
Installation Notes
This is a bolt-on design that requires bolt #53094 and locator pin #62973 for proper installation. Clean those splines thoroughly before you install—any dirt or debris will cause problems down the road. Make sure everything seats properly and torque that bolt to spec. The whole job takes about 20-30 minutes if you’ve got everything ready.
