WINCO 50PTOC4-04 50kW 3-Phase 120/208V 540 RPM PTO Generator
The WINCO 50PTOC4-04 50kW 3-Phase 120/208V PTO Generator delivers professional-grade performance for agricultural, commercial, and industrial operations requiring reliable off-grid or backup power. Designed and assembled in the USA, this generator converts your tractor’s PTO horsepower into clean, continuous, utility-grade electricity — ideal for powering large motors, irrigation systems, and full-scale facilities.
Operating at 540 RPM PTO input, the 50PTOC4-04 produces 50,000 surge watts and 42,000 continuous watts of three-phase power at 120/208V, requiring a 100 HP tractor to achieve full rated output. Its brushless industrial generator end features an AS440 automatic voltage regulator (±1%), maintaining precise, stable output with less than 5% total harmonic distortion (THD) — ensuring compatibility with sensitive electronics and industrial equipment.
Built for durability, the generator uses Winco’s heavy-duty cast-iron gearcase, a proven design with over six decades of reliable service in agricultural environments. The double-layer concentric stator winding, 2/3-pitch rotor, and Class H insulation provide superior efficiency, thermal endurance, and electrical performance. Safety features include a bonded neutral, ground lug, and a large 3.5-inch frequency meter for accurate 60 Hz speed monitoring. With its IP23 protection rating and maintenance-free bearings, this generator is made for continuous duty in tough field conditions.
The power panel offers flexible connectivity with two NEMA 5-20 120V 20A duplex outlets, one NEMA 6-50 240V 50A outlet, and a 350A full-power Anderson receptacle (plug included) for high-capacity loads. Designed for Category 2 three-point hitch or PTO trailer setups, the 50PTOC4-04 is both portable and rugged. Every Winco PTO generator is 100% load-tested before shipping and backed by a 3-year commercial warranty, ensuring long-term reliability and performance you can trust.
