The WINCO W85PTOS-03 85kW 1-Phase 120/240V PTO Generator is the ultimate power solution for agricultural, commercial, and industrial users who demand reliability and strength. Designed and assembled in the USA, this heavy-duty model converts your tractor’s PTO horsepower into 85,000 continuous watts of clean, stable power — enough to operate large facilities, entire farms, or major construction sites with confidence and efficiency.

Winco’s legendary cast-iron gearcase with helical gears delivers long-term durability and smooth torque transfer. A large 3.5-inch frequency meter allows for precise PTO speed management, while the Square D premium circuit breakers provide industry-leading protection. The generator’s bonded neutral, ground lug, and protective PTO shield enhance safety during operation. Every Winco generator is 100% load-tested at the factory before shipment, ensuring unmatched quality and reliability.
Connectivity is robust and versatile with a 350A full-power Anderson plug (included), a NEMA 6-50 50A 240V outlet, and a NEMA 5-20 120V 20A duplex outlet. The W85PTOS-03 features Class H insulation, IP23-rated protection, and a lifting eye for easy transport and installation. With its heavy-duty steel frame and a 3-year commercial warranty, this PTO generator stands as one of the most powerful and reliable options in Winco’s lineup — ready to perform in any environment.
