The WINCO 50PTOT4-03 50kW 1-Phase 120/240V PTO Generator delivers exceptional power and reliability for agricultural, commercial, and industrial operations. Built with American craftsmanship and engineered for long-term dependability, this model transforms your tractor’s PTO into a high-capacity power source capable of supporting entire facilities, heavy-duty tools, or critical systems during outages.

Operating at 1000 RPM PTO input, the 50PTOT4-03 produces 50,000 surge watts and 40,000 continuous watts of clean, stable single-phase power. Designed for use with a 100 HP tractor, this generator features a brushless industrial alternator with AS440 automatic voltage regulation (±1%), providing precision control and less than 5% total harmonic distortion (THD) — ideal for both sensitive electronics and demanding electrical loads.

Built around Winco’s renowned heavy-duty gearcase, which has proven its strength for over six decades, this PTO generator offers unmatched mechanical reliability. It features a single-layer concentric stator winding, a 2/3-pitch rotor, and Class H insulation, ensuring consistent performance even under continuous-duty conditions. Safety and monitoring are enhanced with a frequency meter, bonded neutral, and ground lug, making it ready for professional-grade operation right out of the box.

The 50PTOT4-03 also includes a 350A full-power Anderson receptacle (plug included) and NEMA 5-20 120V 20A and NEMA 6-50 240V 50A outlets for flexible connectivity. Compatible with Category 2 three-point hitches or PTO trailers, this unit is both portable and powerful. Every WINCO PTO generator is 100% factory-tested in Minnesota and backed by a 3-year commercial warranty, providing reliable performance for years to come.
