The WINCO 35PTOC4-21 36kW 3-Phase 600V PTO Generator is engineered for heavy-duty agricultural, commercial, and industrial power needs — transforming tractor horsepower into clean, utility-grade electricity. Designed and assembled in the USA, this rugged generator provides the high-voltage output and three-phase stability required for large equipment, irrigation systems, and remote facilities.

Operating at 540 RPM PTO input, the 35PTOC4-21 delivers 36,000 surge watts and 30,600 continuous watts at 346/600V three-phase, requiring a 72 HP tractor to reach full rated capacity. The brushless industrial generator end includes an AS540 automatic voltage regulator with ±1% regulation and maintains less than 5% total harmonic distortion (THD) — ensuring clean, stable power for both heavy machinery and sensitive control systems.

Built around Winco’s legendary cast-iron gearcase, proven for more than six decades, this model offers exceptional mechanical strength and long-term durability. Inside, the double-layer concentric stator winding, 2/3-pitch rotor, and Class H insulation deliver superior thermal performance and consistent output. The large 3.5-inch frequency meter makes it easy to maintain the proper 60 Hz operating frequency, while a 175A full-power Anderson receptacle (plug included) provides a robust, secure connection for high-load applications.

Every WINCO 35PTOC4-21 is built for reliability and safety, featuring a bonded neutral, ground lug, and frequency meter standard. It’s compatible with Category 2 three-point hitches or PTO trailer kits for convenient installation and transport. Whether you’re powering large farm systems, industrial machinery, or backup infrastructure, this generator delivers dependable, continuous-duty performance backed by a 3-year commercial warranty — proudly made in the USA.
