The WINCO W145PTOS-4 145kW 3-Phase 120/208V PTO Generator is the pinnacle of high-output, professional-grade power generation. Designed and assembled in the USA, this rugged and reliable model converts your tractor’s PTO horsepower into 145,000 continuous watts of clean, stable, three-phase electricity — ideal for agricultural, commercial, and industrial operations requiring uninterrupted, utility-quality power.

Operating at 1000 RPM PTO input, the W145PTOS-4 produces 503 amps at 120/208V, requiring a 290 HP tractor for full-rated performance. The brushless 4-pole rotating field alternator paired with a SX460 automatic voltage regulator (AVR) delivers precise ±1.5% voltage regulation and less than 5% total harmonic distortion (THD) — ensuring dependable operation for sensitive electronics and heavy machinery alike. Built with Class H insulation and rated at 125°C, this generator is engineered for continuous-duty service under demanding conditions.

The cast-iron gearcase with precision helical gears ensures smooth, quiet operation and superior torque handling. A large 3.5-inch frequency meter makes it easy to maintain proper PTO speed and 60 Hz output, while premium Square D circuit breakers provide industry-leading protection. Winco’s protective PTO shield, bonded neutral, and ground lug further enhance operational safety. Each unit is 100% load-tested at Winco’s Minnesota factory — not statistically sampled — guaranteeing dependable performance from the moment it arrives.

Connectivity is simple and versatile, with a NEMA 5-20 120V 20A duplex outlet, NEMA 6-50 240V 50A outlet, and a 500A main circuit breaker for full power delivery. The W145PTOS-4 includes a lifting eye for easy transport and is IP23-rated for weather and debris resistance. Backed by Winco’s 3-year farm-use warranty, this generator represents unmatched American durability and engineering — a true workhorse built for those who demand the best.
