The WINCO 35PTOT4-21 36kW 1000 RPM PTO Generator is built to deliver reliable, utility-grade power wherever you need it. Designed for agricultural, commercial, and industrial operations, this American-made generator converts your tractor’s PTO horsepower into continuous, clean electricity — ideal for running pumps, welders, grain dryers, or entire facilities during outages.

Operating at 1000 RPM PTO input, the 35PTOT4-21 produces 36,000 surge watts and 30,600 continuous watts, providing robust, stable power to handle large electrical loads with ease. Designed for use with tractors rated at 72 HP or higher, this model ensures consistent voltage and frequency even under heavy load. The brushless industrial generator end uses automatic voltage regulation (±1%) to maintain precision output with less than 5% total harmonic distortion (THD), ensuring smooth operation for both sensitive electronics and high-demand machinery .

Engineered for longevity, the 35PTOT4-21 incorporates Winco’s time-tested cast-iron gearcase, proven to withstand decades of use in harsh agricultural environments. Inside, a double-layer concentric stator winding, 2/3-pitch rotor, and Class H insulation deliver superior electrical efficiency and heat resistance. The large 3.5-inch frequency meter ensures operators can maintain proper 60 Hz PTO speed, while a 175A full-power Anderson receptacle (plug included) provides a secure, high-capacity power connection .

This model includes a bonded neutral, ground lug, and standard frequency meter for safety and code compliance. Compatible with Category 2 three-point hitches or PTO trailers, the 35PTOT4-21 is easy to mount and transport.
