Description
When your bush hog won’t spin up properly or you’re getting vibration from your baler, chances are good your PTO shaft is wearing out. This vital connection between your tractor’s engine and implements takes a beating from constant cycling, shock loads, and exposure to dirt and moisture. A worn shaft means power loss, rough operation, and potential damage to both tractor and equipment—problems that can shut down your operation during critical times.
What You’re Getting
- Standard 540 RPM speed works with most common implements like rotary cutters, balers, and spreaders
- 6-spline design provides secure connection and positive power transfer without slipping
- Precision-machined splines ensure smooth engagement and reduce wear on PTO clutch components
- Heat-treated construction handles full tractor power and resists wear from constant use
Built for Real Farm Work
This shaft fits the popular Massey Ferguson 300 series tractors including models 362, 365, 375, 390, 398, and 399. These are the workhorses you’ll find on family farms and custom operations, powering everything from pasture maintenance to hay production. Whether you’re cutting brush, baling hay, or spreading manure, this shaft transfers power reliably to get the job done.
Made to Last
PTO shafts see some of the toughest duty on your tractor, handling tremendous torque while spinning constantly. This replacement features robust steel construction that stands up to shock loads and maintains proper spline engagement even after thousands of hours. The precision manufacturing ensures it fits right and operates smoothly from day one.
Installation Notes
Clean the PTO output housing thoroughly before installation—any dirt or corrosion prevents proper seating and causes premature wear. Apply a thin coat of grease to the splines during assembly. Always verify your implement operates at 540 RPM before connecting to prevent equipment damage. Remember to disengage the PTO and shut off the engine before hooking up implements.
