PTO (Power Take-Off) Assemblies transfer engine power to auxiliary equipment such as hydraulic pumps, generators, or winches. Typically mounted directly to the vehicle’s transmission housing, they utilize gears and a rotating output shaft to deliver mechanical energy. Assemblies include input and output shafts, housings, gears, bearings, and often a clutch for engagement/disengagement. Key technical considerations include gear ratios, input/output speed, and torque capacity, dictated by the driven accessory’s requirements. Variations exist for direct mount, remote mount, and specific transmission types.
