The Winco W70PTO-3/A 69,000-watt tractor PTO-driven generator converts standard 540 RPM tractor power take-off torque into heavy-duty 120/240V single-phase prime and emergency electrical power across agricultural farms, dairy complexes, irrigation stations, and remote rural ranches. Engineered to pair with 138 HP or larger agricultural tractors, this high-output power plant produces 69,000 continuous running watts (287 running amps) stabilized by an electronic Automatic Voltage Regulator (AVR ±1%) for sensitive electronic controls. Outfitted with an oil-bath cast-iron gearcase utilizing precision-machined helical gears, a 350-amp Anderson full-power receptacle, a 5-20 20A duplex outlet, and an oversized analog frequency meter for rapid tractor engine throttle adjustments, it equips farmers and ranchers with robust whole-property power generation and emergency storm outage reliability.

Best Used For:

  • Agricultural Irrigation and Deep Well Pumping: Driving large high-amperage 240V electric submersible well motors, center pivot irrigation systems, and manure slurry pumps.
  • Whole-Dairy and Poultry Complex Power: Energizing automatic milking parlors, bulk tank milk chillers, egg collection systems, and massive barn ventilation fan arrays during utility outages.
  • Rural Homestead and Emergency Farm Grid Backup: Supplying continuous 287-amp full-capacity electricity to commercial farm transfer switches to power houses, workshops, and grain augers simultaneously.

Key Performance & Safety Features

  • High-Capacity 69,000 Running Watts: Delivers 287 continuous amperes at 240V single-phase to start and run large industrial motor loads and heavy inductive heating elements.
  • Electronic Automatic Voltage Regulation (AVR): Regulates output voltage within ±1% to prevent harmful electrical spikes, safeguarding computerized barn automation and sensitive electronics.
  • Heavy-Duty Cast Iron Helical Gearcase: Sealed oil-lubricated cast-iron housing with helical cut gearing runs cooler and quieter than spur gears under full mechanical horsepower transfer.
  • Standard 540 RPM Tractor PTO Input: Connects directly to Category 2/3 tractor power take-off shafts operating at 540 RPM (requires 138 tractor engine horsepower).
  • Heavy-Duty 350A Anderson Power Receptacle: High-amperage Anderson connector bus provides full generator amperage extraction safely to main service distribution panels.
  • Oversized PTO Diagnostic Frequency Meter: Clear dashboard meter visualizes 60 Hz operating frequency to allow the tractor operator to set and lock precise engine throttle.

Pro-Tip: Before applying large electric motor loads, adjust tractor engine RPM until the generator frequency meter needle points dead-center at 60 Hz; as heavy inductive motor loads kick on, the helical gearcase and electronic AVR will stabilize power output without engine stalling.
