The WINCO W70PTOS-3 69kW PTO Generator is built for serious power users who need reliable, utility-grade performance for farms, commercial sites, or industrial operations. Proudly designed and assembled in the USA, this heavy-duty model converts your tractor’s PTO horsepower into continuous, clean energy capable of running large facilities, pumps, or entire farms with ease.

Operating at 1000 RPM PTO input, the W70PTOS-3 delivers 69,000 continuous watts (287 amps) of single-phase power at 120/240V, requiring a 138 HP tractor to reach full-rated output. Its brushless alternator with AS440 automatic voltage regulator (AVR) maintains ±5% voltage regulation and less than 5% total harmonic distortion (THD) — ensuring smooth, consistent output safe for sensitive electronics and heavy-duty machinery.

Winco’s cast-iron gearcase with helical gears ensures quiet, efficient power transfer and long-term reliability. The 4-pole rotating field design and Class H insulation guarantee thermal stability and endurance for continuous-duty use. A 3.5-inch frequency meter provides accurate RPM monitoring for precise 60 Hz operation, while Square D circuit breakers offer industry-leading electrical protection. Every unit is 100% load-tested at the factory before shipment — ensuring the highest quality and reliability standards.

Equipped with a NEMA 5-20 120V 20A duplex outlet and a 350A full-power Anderson receptacle (plug included), the W70PTOS-3 offers flexible power delivery options. It features a bonded neutral, ground lug, lifting eye, and protective PTO shield for safety and convenience. With its IP23-rated protection, 2.75-pint oil capacity, and steel construction, this generator is built to perform year after year. Backed by a 3-year commercial warranty, it’s the dependable solution professionals trust when failure is not an option.
