When your operation demands high-capacity, reliable power in a PTO-driven package built for the toughest environments, the WINCO W85PTOS-21 steps up with industrial-grade performance and professional-level durability. Designed for agricultural, commercial, and remote-site use, this generator converts your tractor’s PTO output into clean, utility-quality three-phase power — ready for major loads, continuous duty, and full-system support.

Operating at a 1000 RPM PTO input, the W85PTOS-21 delivers 85 kW of continuous power at 346/600 V three-phase, giving you serious output for large motors, facility systems, or critical standby loads. Its brushless alternator design, paired with Winco’s cast-iron gearcase and helical gearing, ensures long-term mechanical strength and minimal maintenance. A large 3½-inch frequency meter helps you monitor PTO speed and maintain a true 60 Hz output, while premium circuit breakers and a protective PTO shield enhance safety and serviceability. The model is also 100 % factory load-tested before shipment — no statistical sampling here — giving you confidence in real-world performance. 

Backed by Winco’s American engineering and rugged build, the W85PTOS-21 is ideal for facilities where power reliability is non-negotiable. Whether you’re powering grain dryers, irrigation systems, backup panels, or remote job-site loads, this generator gives you the capacity, robustness, and clean output to keep operations running smoothly.
