The WINCO W150PTOS-3 150kW PTO Generator is the most powerful single-phase PTO unit in Winco’s lineup — delivering professional-grade performance for large agricultural, commercial, and industrial applications. Designed, engineered, and assembled in the USA, this model converts your tractor’s PTO power into 150,000 continuous watts of clean, stable energy capable of running full facilities, heavy-duty machinery, or backup systems for large operations.

Driven by a 1000 RPM PTO input, the W150PTOS-3 provides 625 amps of output at 120/240V single-phase, requiring a 300 HP tractor to achieve its full rated capacity. The brushless alternator with AS440 automatic voltage regulator (AVR) ensures ±5% voltage regulation and less than 8% total harmonic distortion (THD) — ideal for powering sensitive electronics and large motor loads with confidence. This 4-pole rotating-field generator is built for continuous-duty use with Class H insulation, a 600A main circuit breaker, and a heavy-duty cast-iron gearcase designed to handle massive torque loads.

Winco’s gearcase features helical gears for smooth, quiet operation and long-term durability. A large 3.5-inch frequency meter provides accurate PTO speed monitoring, while premium Square D circuit breakers deliver industry-leading protection. Every unit is 100% load-tested before leaving Winco’s Minnesota factory to ensure reliable performance under real-world conditions.

The W150PTOS-3 offers versatile connectivity with (1) NEMA 5-20 20A duplex outlet, (1) NEMA 6-50 50A outlet, and a 600A main breaker for full-power output. A bonded neutral, ground lug, and protective PTO shield come standard for safety and compliance. Compatible with PTO trailer kits and manual transfer switches, this generator is built to perform in the toughest environments — backed by Winco’s 3-year commercial warranty for unmatched peace of mind.
