The Power Take-Off, most typically referred to by its acronym, PTO, is a common sort of mechanical electricity shipping in the mobile equipment marketplace. The PTO is a strategy of transferring higher energy and torque from the engine (typically through the transmission) of vans and tractors. In mixture with gearboxes and pump mounts, almost any sort of mechanical electrical power transmission is achievable.

There are 3 frequent electrical power consider-off strategies in the cell device marketplace tractor style, truck transmission fashion and motor crankshaft-pushed, although the latter is not typically referred to as a PTO. The crankshaft-driven approach of power transmission is usually 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 change the pump. This configuration of drive is not normally referred to as a PTO, even so.

The tractor PTO goes back again rather much as considerably as tractors. Most early PTOs have been driven from the transmission, which becoming situated at the back again of the tractor, allows for simple place of an output shaft. The transmission variety of PTO is only engaged when the transmission clutch is also engaged, and is coupled straight to transmission, so that when the clutch loads/2019/07/Hydraulic-PTO-Drive-Gearbox-Spped-Increaser-1.png]#is depressed, the PTO is not driven.
