Description
When your PTO shaft starts clicking or vibrating, it’s usually telling you that worn yokes are causing misalignment and putting stress on the whole driveline. This Weasler Bondioli Series 5 implement yoke gives you the precision fit you need to keep power flowing smoothly from your tractor to your implements. Whether you’re running a mower, tiller, or other mid-size equipment, this yoke handles the constant angle changes and power transmission that smaller yokes just can’t manage.
What You’re Getting
- Precision-machined 1-1/4 inch round bore with keyway for secure, no-slip connection
- Heavy-duty construction that handles the angles and shock loads of real field work
- Perfect bearing-to-end spacing (3.86 inches) for proper driveline geometry
- Quality cross and bearing design that keeps U-joints running smooth and true
- Direct replacement for worn or damaged Series 5 yokes
Built for Real Farm Work
This Series 5 size fits tractors and implements in the 40-80 horsepower range, making it perfect for rotary cutters, hay tedders, smaller tillers, and other mid-duty PTO equipment. You’ll find this bore size on implements where manufacturers want reliable power transfer without the bulk and cost of larger series components.
Made to Last
Weasler doesn’t mess around with PTO parts – they know how expensive downtime can be during critical seasons. This yoke is forged tough and machined to tight tolerances so it maintains proper fit even after seasons of use. The bearing surfaces are ground smooth to reduce wear on U-joints, and the overall design balances strength with the flexibility needed for constantly changing operating angles.
Installation Notes
This yoke slides onto your implement’s 1-1/4 inch round shaft and locks in place with the keyway. Make sure you’re matching Series 5 components throughout your driveline – mixing series sizes causes premature wear and dangerous vibrations. Check that your driveline length works with the 3.86-inch bearing-to-end measurement.
