WA Wide Angle Joints

WA (Wide Angle) joints are specialized components used in tractor power take-off (PTO) shafts to allow for greater angular movement and flexibility. They are designed to accommodate the varying angles that occur between the tractor’s PTO stub shaft and the implement’s input shaft.

When a tractor and implement are not perfectly aligned, such as when working on uneven terrain or using implements with adjustable angles, the PTO shaft needs to be able to flex and accommodate these changes in angle. This is where WA joints come into play.

WA joints consist of two yokes connected by a cross-shaped bearing assembly. The yokes are attached to the tractor’s PTO stub shaft and the implement’s input shaft, respectively. The cross-shaped bearing assembly allows for the rotation and articulation of the PTO shaft, compensating for angular misalignment between the tractor and implement.

The key feature of WA joints is their ability to provide a wider range of movement compared to standard universal joints. They can handle larger angles, typically up to 80 degrees or more, depending on the specific design. This increased flexibility allows the PTO shaft to operate smoothly and reliably even when the tractor and implement are not perfectly aligned.

WA joints are commonly used in agricultural applications where implements require a significant range of motion, such as mowers, balers, and sprayers. They are especially useful when working with implements that have adjustable angles or when navigating uneven terrain.
