Description
When you’re pulling heavy implements like big disc harrows, chisel plows, or wide finishing mowers, that jerky PTO vibration isn’t just annoying—it’s hard on everything from your tractor transmission to the implement gearbox. A worn constant velocity joint can’t smooth out the power pulses, and that rough power delivery beats up expensive equipment fast. This Weasler CV head restores that smooth, steady power flow your implements need to work right and last longer.
What You’re Getting
- Constant velocity design eliminates the jerky power delivery of worn CV joints
- 1-3/8 inch diameter with 21 spline configuration for positive engagement
- Heavy-duty construction handles the high torque of large tractors and implements
- Direct replacement design—no modifications needed for most applications
- Built to Weasler’s agricultural standards for reliable field performance
Built for Real Farm Work
This CV head is sized for the bigger tractors running serious implements—think 100+ horsepower machines pulling wide tillage tools, heavy-duty rotary cutters, or large hay equipment. The 21 spline connection handles the high torque these applications demand, while the constant velocity design keeps power delivery smooth even when working uneven ground or making tight turns.
Made to Last
Farm work doesn’t go easy on PTO components, and this CV head is built to handle it. The internal mechanism is designed to maintain smooth operation through thousands of hours of varying loads and angles. Quality materials and precision manufacturing mean this part keeps doing its job season after season, even in demanding applications.
Installation Notes
This is a direct replacement for most 1-3/8 inch 21 spline applications. Check your existing CV joint for the 2580 series designation to ensure compatibility. During installation, inspect the mating components for wear and clean all splines thoroughly before assembly. Proper greasing after installation helps ensure long service life.
