Description
If you’ve ever noticed that clicking sound coming from your PTO shaft when you’re turning corners or working uneven ground, you know why constant velocity joints matter. Regular universal joints bind up when the angles change, causing vibration, wear, and power loss. This CV driveline eliminates that problem with smooth power transfer at any angle, keeping your implements running efficiently whether you’re on hillsides or flat ground.
What You’re Getting
- Constant velocity joints that maintain steady power output even at extreme angles
- 55-inch compressed length handles most standard applications
- Auto-Lok tractor yoke connects securely without fumbling with pins
- Category 6 rating handles medium to heavy-duty implements
- Star tubing design provides strength while allowing smooth telescoping action
Built for Real Farm Work
This driveline works perfectly with implements that need the Category 6 strength and CV smoothness—think heavy rotary cutters, large hay equipment, spreaders, and tillage tools. The 1-3/8 inch 6-spline connection fits a wide range of tractors, from mid-size utility models up to larger row-crop machines. When you’re running equipment that sees varying terrain or heavy loads, the CV joints keep everything spinning smoothly.
Made to Last
Weasler builds these drivelines knowing that PTO failure isn’t just expensive—it can be dangerous. The CV joints are precision-manufactured to handle the constant flexing that comes with field work, while the star tubing resists twisting under load. The Auto-Lok connection eliminates the wear and tear that comes from loose-fitting pin-style yokes.
Installation Notes
The Auto-Lok yoke slides right onto your tractor’s PTO splines and locks automatically—no pins to lose or forget. Make sure your implement end fits the 1-3/8 inch 6-spline clamp yoke before ordering. Always check that the compressed length gives you enough working range for your specific application.
