The Power Take-Off, most typically referred to by its acronym, PTO, is a common form of mechanical energy shipping and delivery in the mobile machine market place. The PTO is a strategy of transferring higher energy and torque from the motor (usually through the transmission) of trucks and tractors. In blend with gearboxes and pump mounts, nearly any sort of mechanical power transmission is possible.

There are a few frequent electrical power get-off techniques in the cellular device market place tractor type, truck transmission type and motor crankshaft-driven, though the latter is not generally referred to as a PTO. The crankshaft-driven approach of electricity transmission is often employed for hydraulic pumps mounted to the entrance of an on-highway truck, this kind of as a plow/spreader or cement mixer. A tiny shaft with U-joints attaches to a yoke coupler to switch the pump. This configuration of push is not usually referred to as a PTO, even so.

The tractor PTO goes back quite much as far as tractors. Most early PTOs were driven from the transmission, which becoming positioned at the back of the tractor, allows for simple area of an output shaft. The transmission kind of PTO is only engaged when the transmission clutch is also engaged, and is coupled directly to transmission, so that when the clutch is depressed, the PTO is not driven.
