WINCO 50PTOC4-17 50kW 3-Phase 120/240V 540 RPM PTO Generator
The WINCO 50PTOC4-17 50kW 3-Phase 120/240V PTO Generator delivers professional-grade power performance straight from your tractor. Built for agricultural, industrial, and commercial applications, this model converts PTO energy into reliable, utility-grade electricity to keep your farm, facility, or operation powered when the grid can’t.
Operating at 540 RPM PTO input, the 50PTOC4-17 produces 50,000 surge watts and 42,000 continuous watts of clean, three-phase power at 120/240V, requiring a 100 HP tractor for full output. Its brushless industrial alternator includes a high-precision AS440 automatic voltage regulator (±1%), maintaining stable output with less than 5% total harmonic distortion (THD) — safe for sensitive electronics and large motors alike.
The Winco cast-iron gearcase, refined for over 60 years, ensures unmatched strength and longevity in demanding field conditions. Internally, the double-layer concentric stator winding, 2/3-pitch rotor, and Class H insulation provide exceptional efficiency, heat protection, and continuous-duty reliability. A large 3.5-inch frequency meter allows precise PTO speed monitoring for accurate 60 Hz output.
For flexible connectivity, the 50PTOC4-17 includes two NEMA 5-20 120V 20A duplex outlets, one NEMA 6-50 240V 50A outlet, and a 350A full-power Anderson receptacle (plug included). The generator also features a bonded neutral, ground lug, and IP23 protection rating for safe, weather-resistant operation. Compatible with Category 2 three-point hitches or PTO trailer kits, this unit is as mobile as it is powerful. Proudly made and tested in the USA, it’s backed by Winco’s 3-year commercial warranty, delivering performance and reliability that professionals trust.
