Description
When you’re making hay and your mower conditioner starts shaking or the driveline starts chattering, you know it’s time for a new CV half shaft. This replacement gets you back to cutting smooth and clean, without the vibrations that make your fillings rattle and stress your PTO. It’s the heavy-duty connection between your tractor’s power and your mower’s cutting action—and when it’s working right, you hardly know it’s there.
What You’re Getting
- Complete shield included to keep debris and clothing away from rotating parts
- Auto-Lok yoke connection locks securely to your tractor without pins or clips
- Category 6 CV design handles the constant angles and loads of mower operation
- 40-inch compressed length fits a wide range of mower conditioner setups
- Series 55 North American standard matches most tractor PTO outputs
Built for Real Farm Work
This half shaft is designed for Bush Hog and John Deere mowers and other mower conditioners that need reliable power transfer through constantly changing angles. Whether you’re cutting alfalfa, grass hay, or dealing with uneven ground, this CV setup keeps the power flowing smoothly while your mower follows the contours of the field.
Made to Last
Weasler doesn’t mess around – their components are forged tough and machined to tight tolerances. The CV joints handle the constant flexing and angle changes that come with mowing, while the protective shield keeps stones, crop debris, and loose clothing away from the spinning shaft. It’s built to handle the punishment of daily hay production without leaving you stranded.
Installation Notes
The Auto-Lok yoke slides right onto your tractor’s 1-3/8 inch 21-spline PTO output and locks automatically—no fumbling with pins while the tractor’s running. Check your compressed length before ordering, and make sure your mower’s input matches the implement end. A quick tip: grease the CV joints through the fittings after installation to keep everything running smooth all season long.
