The WINCO 50PTOC4-03 50kW 1-Phase 120/240V PTO Generator is engineered to provide dependable, high-capacity power for farms, construction sites, and commercial operations. Built with Winco’s legendary American-made craftsmanship, this model converts your tractor’s PTO output into clean, consistent, utility-grade electricity — ideal for running entire facilities, pumps, or large equipment during outages or remote work.

Operating at 540 RPM PTO input, this generator produces 50,000 surge watts and 40,000 continuous watts of single-phase 120/240V power. Requiring a 100 HP tractor, it’s designed for heavy-duty applications where reliability and performance are essential. The brushless industrial alternator includes a high-precision AS440 automatic voltage regulator (±1%), maintaining clean output with less than 5% total harmonic distortion (THD) — ensuring safe operation for sensitive electronics, motors, and controls.

Built to last, the 50PTOC4-03 features Winco’s cast-iron gearcase, proven over 60 years of field use for strength and durability. Its single-layer concentric stator winding, 2/3-pitch rotor, and Class H insulation deliver consistent electrical efficiency and heat protection during continuous-duty operation. A large frequency meter, bonded neutral, and ground lug are standard, while the rugged IP23-rated frame provides superior protection in harsh environments.

The power panel includes two NEMA 5-20 20A 120V duplex outlets, one NEMA 6-50 50A 240V outlet, and a 350A full-power Anderson receptacle (plug included). Compatible with Category 2 three-point hitches or PTO trailer kits, the 50PTOC4-03 offers flexibility for mobile or stationary setups. Assembled and load-tested in the USA, this generator represents the gold standard in PTO-driven reliability — backed by Winco’s 3-year commercial warranty for unmatched peace of mind.
