Category 4 CV Tractor Yoke with Safety Slide Lock for 1-3/8 Inch 6-Spline PTO Shafts

Description

When you’re running implements that need to turn corners or work on uneven ground, a standard PTO connection just won’t cut it. Those tight turns and changing angles put a lot of stress on your driveline, causing vibration, premature wear, and sometimes complete failure when you least expect it. This Category 4 CV tractor yoke from Weasler is built knowing that PTO failure isn’t just inconvenient—it’s dangerous. The constant velocity design keeps power flowing smoothly no matter what angle your implement takes.

What You’re Getting

• Constant velocity design that maintains smooth power transfer through tight turns and uneven terrain
• Safety slide lock mechanism that gives you secure engagement and easy disconnection
• Category 4 strength built for higher horsepower tractors and demanding applications
• 1-3/8 inch diameter with 6-spline configuration for precise fit on your PTO shaft
• Equal arm design that balances the load and reduces stress on driveline components

Built for Real Farm Work

This Category 4 yoke is designed for the bigger tractors and heavier implements where standard yokes struggle. It handles medium to heavy-duty applications—think bigger rotary cutters, heavy-duty tillers, and implements that see constant use in tough conditions. Whether you’re running a large finishing mower around obstacles or powering through with implements that need to articulate, this CV yoke delivers the strength and flexibility you need when the work gets demanding.

Made to Last

Weasler uses quality materials and proven design to handle the punishment of agricultural applications. The construction features enhanced lubrication retention that keeps those needle bearings running smooth longer between service intervals, while precision-machined components maintain exact angles, eliminating the slop that causes premature wear and vibration.

Installation Notes

This is a direct replacement for your existing 1-3/8 inch, 6-spline PTO connection. Take your time with the spring tension in the safety slide lock—it’s under pressure and wants to fly apart if you’re not careful, and make sure the grease fitting stays accessible after you put everything together. The CV design means proper phasing is critical, so mark your positions before any disassembly work.
