The WINCO 55PTOT4-18 55kW 3-Phase 277/480V PTO Generator is built to provide commercial-grade power wherever it’s needed — from farms and job sites to industrial facilities. Engineered and assembled in the USA, this unit converts your tractor’s horsepower into clean, stable, utility-quality electricity for heavy-duty operations, irrigation systems, or complete facility backup.

Operating at 1000 RPM PTO input, the 55PTOT4-18 produces 55,000 surge watts and 46,400 continuous watts at 277/480V three-phase, requiring a 110 HP tractor for full rated performance. Its brushless industrial generator end features an AS440 automatic voltage regulator (±1%) and delivers power with less than 5% total harmonic distortion (THD) — ensuring dependable, consistent output for sensitive electronics and demanding equipment alike.

Built on Winco’s time-tested cast-iron gearcase, trusted for over 60 years of proven reliability, this generator is designed for durability and long-term performance. The double-layer concentric stator winding, 2/3-pitch rotor, and Class H insulation ensure superior heat resistance and electrical efficiency. The large 3.5-inch frequency meter provides real-time RPM monitoring for precise 60 Hz operation, while the rugged IP23-rated enclosure withstands the elements for extended service life.

For power delivery, the 55PTOT4-18 includes a 350A full-power Anderson receptacle (plug included), ensuring reliable, high-capacity connectivity. A bonded neutral, ground lug, and standard frequency meter ensure safe and compliant operation. Compatible with Category 2 three-point hitches or PTO trailer kits, this unit offers flexible deployment options. 100% load-tested at the Winco factory and backed by a 3-year commercial warranty, this PTO generator delivers the performance professionals rely on year after year.
