The WINCO W145PTOS-17 145kW 3-Phase 120/240V PTO Generator is built for demanding agricultural, commercial, and industrial operations that require reliable, high-capacity power. Proudly designed and assembled in the USA, this model converts your tractor’s PTO output into 145,000 continuous watts of clean, stable, utility-grade electricity — ideal for running large facilities, irrigation systems, or heavy-duty equipment.

Operating at 1000 RPM PTO input, the W145PTOS-17 produces 436 amps at 120/240V three-phase, requiring a 290 HP tractor for full-rated output. The brushless 4-pole rotating field alternator features a SX460 automatic voltage regulator (AVR) to maintain ±1.5% voltage regulation with less than 5% total harmonic distortion (THD), delivering smooth and consistent power for both sensitive electronics and high-demand machinery.

Engineered for long-term durability, Winco’s cast-iron gearcase with precision helical gears ensures efficient torque transfer, quiet operation, and decades of service. The Class H insulation is rated for continuous-duty operation at 125°C, providing exceptional thermal endurance under heavy load. Each generator undergoes 100% full-load testing before shipment — no statistical sampling — ensuring dependable performance from day one.

For safety and convenience, the W145PTOS-17 includes a 3.5-inch frequency meter, 450A main circuit breaker, bonded neutral, ground lug, and protective PTO shield. The power panel provides flexible connectivity with a NEMA 5-20 120V 20A duplex outlet and a NEMA 6-50 240V 50A outlet, while a lifting eye simplifies installation and transport. Optional accessories — such as a PTO drive shaft, off-road trailer, or manual transfer switch — make it easy to customize your setup. With its 3-year farm-use warranty, the W145PTOS-17 stands as one of the most powerful and dependable PTO generators in Winco’s lineup.
