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.
