The WINCO W165PTOS-18 165kW 3-Phase PTO Generator is the ultimate solution for heavy-duty agricultural, commercial, and industrial operations demanding reliable, high-capacity power. Proudly engineered and assembled in the USA, this generator converts your tractor’s PTO horsepower into 165,000 continuous watts of clean, three-phase electricity — ready to power large buildings, irrigation systems, or mission-critical equipment during outages or remote operations.

Operating at 1000 RPM PTO input, the W165PTOS-18 provides 248 amps at 277/480V three-phase, requiring a 290 HP tractor for full output. The 4-pole rotating field brushless alternator includes an SX460 automatic voltage regulator (AVR) that maintains ±1.5% voltage regulation and less than 8% total harmonic distortion (THD) — ensuring smooth, stable, and utility-grade power for sensitive electronics, motors, and lighting systems.

Built for endurance, this model features Winco’s cast-iron gearcase with precision helical gears, providing quiet and efficient torque transfer under heavy load. The Class H insulation system is rated for 125°C continuous operation, guaranteeing long life even in demanding duty cycles. Every generator is 100% load-tested before shipment — Winco never uses statistical sampling — to ensure consistent, high-quality performance.

For safety and convenience, the W165PTOS-18 includes a large 3.5-inch frequency meter, 250A main circuit breaker, bonded neutral, ground lug, and protective PTO shield. A 5-wire full-power 350A Anderson connector (plug included) ensures easy, secure power delivery, while optional accessories like PTO drive shafts, off-road trailers, and manual transfer switches make it simple to tailor your setup. With its IP23-rated protection, heavy-duty steel frame, and 3-year farm-use warranty, this generator is built to perform — wherever reliable power is essential.
