WINCO W70PTO-3 69kW 1-Phase 120/240V 540 RPM PTO Generator
The WINCO W70PTO-3 69kW 1-Phase 120/240V PTO Generator delivers exceptional performance and reliability for large-scale farm, commercial, and industrial operations. Built in the USA and tested under full load before leaving the factory, this PTO-driven unit converts your tractor’s power into clean, consistent, utility-grade electricity — ensuring that you’re never left without dependable backup or off-grid energy.
Operating at 540 RPM PTO input, the W70PTO-3 produces 69,000 continuous watts (287 amps) of single-phase output at 120/240V, requiring a 138 HP tractor to achieve full capacity. It features an AS440 automatic voltage regulator that maintains ±5% voltage regulation and ensures less than 5% total harmonic distortion (THD) — providing safe, stable power for everything from large motors to sensitive electronics.
Winco’s cast-iron gearcase with helical gears ensures smooth torque transfer and long-lasting durability, even under continuous-duty operation. The 4-pole rotating field brushless alternator design minimizes maintenance while maximizing efficiency, and the Class H insulation provides superior heat resistance and electrical stability. A large 3.5-inch frequency meter allows for precise RPM monitoring, and premium Square D circuit breakers offer professional-grade protection for your electrical systems.
For convenience and safety, the W70PTO-3 includes a 350A full-power Anderson connector (plug included), bonded neutral, ground lug, and protective PTO shield. Optional accessories — such as drive shafts, off-road PTO trailers, and manual transfer switches — enhance flexibility and ease of setup. Weighing 972 lbs and constructed from heavy-duty steel, this generator is designed for decades of reliable performance. With a 3-year commercial warranty and 100% factory load testing, the W70PTO-3 sets the standard for American-made PTO power.
