Description
When your PTO yoke starts getting sloppy or the keyway starts showing wear, you’ll feel it in the cab and see it in your implements. Vibrations that destroy U-joints, damage implement gearboxes, and create dangerous operating conditions aren’t just annoying—they’re expensive problems waiting to happen. This Weasler Bondioli Series 5 implement yoke gives you back that solid, smooth connection between your tractor and your hardworking implements.
What You’re Getting
- Precise 1.19 inch bearing caps that keep universal joints running true for smooth power transfer
- 1-3/8 inch round bore with 5/16 inch keyway that fits tight and stays put under load
- Built to Bondioli Series 5 specifications for proper fit with matching driveline components
- 3.86 inch center-of-bearing to end measurement maintains correct driveline geometry
Built for Real Farm Work
Series 5 components are sized for medium-duty applications on compact to mid-size tractors running implements like rotary cutters, hay equipment, and tillage tools. You’ll find this size on everything from finishing mowers to smaller feed mixers where you need reliable power transfer without the bulk of heavier series.
Made to Last
Weasler doesn’t just make generic driveline parts – they understand the punishing conditions farm equipment faces. The round bore is machined to tight tolerances so it stays snug on your implement shaft, while the keyway is cut deep enough to handle full power without wallowing out over time.
Good to Know
This is a direct replacement that slides right onto your implement’s 1-3/8 inch input shaft. Make sure you match the series number with your existing driveline—Series 5 components need to work with other Series 5 parts for proper fit and safe operation. A little anti-seize compound on the keyway makes future removal easier.
