This is an aftermarket replacement Power Take-Off (PTO) shaft, compatible with Bondioli & Pavesi specifications, identified by the part number WE7G9N086CE0070A8NO. Designed for agricultural and industrial machinery, this non-OEM alternative PTO shaft is engineered to transmit power efficiently from the tractor's PTO output to various implements. A key feature of this shaft is its integrated free-wheel (overrunning) clutch, which allows the implement's driveline to continue rotating freely even when the tractor's PTO is disengaged. This is particularly crucial for implements with high rotational inertia, such as balers, mowers, or rotary tillers, preventing damage to the tractor's PTO system. The shaft features standard spline connections for broad compatibility. The tractor side connection is a 1 3/8" Z6 spline, ensuring a secure fit with most standard tractor PTO outputs. On the implement side, it utilizes a 1 3/4" Z6 spline, suitable for heavy-duty implements requiring a larger connection. This replacement PTO shaft offers a cost-effective solution for maintaining the operational integrity and safety of your machinery, providing reliable power transmission and protection against driveline shock loads. Ensure to verify the specific length and safety features required for your application before installation.
