PTO Power Unit

Complete Hydraulic Unit with Built-In Relief Valve, Reservoir and Site Glass

Webster PTO units are tractor-driven, completely self contained hydraulic power supply systems for agricultural applications. They mount on a tractor PTO shaft to provide hydraulic power for front end loaders, snow plows, mowers, spreaders, log splitters, post hole augers, and other hydraulic tools.
Available in 540 and 1000 rpm models, Webster PTO units feature lightweight high strength aluminum alloy housings, and hardened steel shafts & gears.  At the heart of the PTO is a proven Webster YC Series pressure balanced hydraulic pump with a built-in relief valve, set at 2250 psi (155bar). Other standard features include reservoir, filler/breather and sight glass to insure proper fluid level.
