1-3/8 in. 6-Spline Overrun Coupler

This overrun coupler is engineered for PTO-driven agricultural equipment, allowing the shaft to rotate in one direction while spinning freely in the opposite direction. This mechanism controls implement speed when the tractor is slowing down, preventing the implement from exceeding tractor speed for safer operation.

Designed with a 1-3/8 in. 6-spline male end for tractor attachment and a 1-3/8 in. 6-spline female end for implement connection, this coupler provides secure power transfer. The overrunning clutch design is essential for implements with high inertia, such as mowers, rotary cutters, and other PTO-driven equipment.
