PTO Shaft Adaptor & Spline Bushings

A PTO shaft adapter and spline bushings are essential components used in agricultural applications to connect and adapt different sizes and types of PTO shafts. They enable compatibility between the tractor’s PTO output shaft and the implement’s input shaft, ensuring efficient power transmission.

PTO Shaft Adapter: A PTO shaft adapter, also known as a PTO coupling or PTO adapter, is a device used to connect two PTO shafts that have different sizes, spline counts, or configurations. It serves as an intermediary link between the tractor and the implement, allowing them to connect and transfer power effectively.

PTO shaft adapters typically consist of male and female ends that can be attached to the respective PTO shafts. They may have different spline types, such as standard splines, involute splines, or triangular splines, depending on the specific PTO shaft configuration. The adapter ensures a secure and reliable connection between the tractor and the implement, enabling the transfer of rotational power.

Spline Bushings: Spline bushings, also known as spline adapters or PTO shaft reducers, are used when there is a difference in the spline count or size between the tractor’s PTO output shaft and the implement’s input shaft. Spline bushings are inserted into the implement’s input shaft to adapt it to the size or count of the tractor’s PTO shaft.

Spline bushings are available in various configurations, including different spline counts and sizes. They are typically made of durable materials like steel or hardened alloys to withstand the high torque and rotational forces experienced in agricultural applications.
