The WINCO W85PTOS-18 85kW PTO Generator delivers powerful, utility-grade performance for agricultural, commercial, and industrial users who demand dependable, high-capacity energy. Proudly engineered and assembled in the USA, this rugged model converts your tractor’s PTO power into 85,000 continuous watts of clean, three-phase electricity — ideal for large-scale facilities, irrigation systems, or heavy machinery requiring reliable, continuous-duty operation.

Operating at 1000 RPM PTO input, the W85PTOS-18 produces 102 amps at 277/480V, requiring a 170 HP tractor to achieve full-rated output. Its 4-pole rotating field brushless alternator with an AS440 automatic voltage regulator (AVR) provides ±5% voltage regulation and less than 5% total harmonic distortion (THD) — delivering stable, clean power suitable for both sensitive electronics and heavy motor loads.

Winco’s cast-iron gearcase with precision helical gears ensures quiet, efficient operation and exceptional durability under load. A 3.5-inch frequency meter provides accurate PTO speed monitoring, while premium Square D circuit breakers offer industry-leading protection. Safety features include a bonded neutral, ground lug, and protective PTO shield, ensuring secure operation in any environment. Each unit undergoes 100% full-load factory testing before shipment — never statistical sampling — guaranteeing performance and reliability straight from the factory.

Connectivity is effortless with the included 4-wire 350A full-power Anderson plug, providing flexibility for high-demand applications. Optional accessories like PTO drive shafts, off-road PTO trailers, and manual transfer switches make it easy to create a complete mobile or stationary power setup. With its IP23-rated protection, Class H insulation, and 3-year warranty, the W85PTOS-18 stands as a top-tier American-made PTO generator built to power through the toughest challenges.
