WINCO W105PTOS-4 105kW 3-Phase 120/208V 1000 RPM PTO Generator
The WINCO W105PTOS-4 105kW 3-Phase PTO Generator is a powerhouse built for commercial, industrial, and agricultural users who require high-capacity, reliable power. Designed and assembled in the USA, this rugged unit converts your tractor’s PTO into clean, utility-grade electricity capable of running large operations, irrigation systems, or heavy equipment with ease and precision.
Operating at 1000 RPM PTO input, the W105PTOS-4 produces 105,000 continuous watts (364 amps) of 120/208V three-phase power, requiring a 210 HP tractor for full-rated performance. Equipped with a brushless 4-pole rotating field alternator and SX460 automatic voltage regulator, it maintains ±1.5% voltage regulation and less than 5% total harmonic distortion (THD) — ensuring stable, efficient power delivery for both sensitive electronics and industrial-grade machinery.
Built around Winco’s cast-iron gearcase with helical gears, this PTO generator is engineered for long-lasting durability and quiet operation. A large 3.5-inch frequency meter provides precise RPM monitoring for accurate 60 Hz performance, while premium Square D circuit breakers deliver professional-grade protection for your electrical systems. Every unit is 100% factory load-tested, guaranteeing quality and reliability from day one.
Connectivity is made simple and safe with a 350A full-power Anderson connector (plug included), NEMA 6-50 50A 240V outlet, and NEMA 5-20 20A duplex 120V outlet. Standard features include a bonded neutral, ground lug, protective PTO shield, and lifting eye for convenient setup. With a heavy-duty steel frame and IP23-rated protection, this generator is built to withstand demanding environments. Backed by a 3-year commercial warranty, the W105PTOS-4 provides dependable power you can trust — wherever your work takes you.
