This is an original front PTO shaft for the host tractor. It transmits engine torque from the front of the crankshaft to driven implements mounted on the front linkage. The shaft assembly includes all necessary components for a complete installation. A worn or damaged front PTO shaft causes vibration and can prevent proper engagement with the implement's driveline. This component is machined to the original geometry, ensuring the spline engagement and overall length match the factory assembly without requiring additional shims or modifications.
