25KW Power Take-Off Generator
Winco 120/240Vac Single phase

PTO Generators are designed as a standby electrical power supply for farm applications or any site that has an engine with a power take-off.  They can utilize a power take-off from tractors, bulldozers, or trucks as the prime mover.  Units are equipped with a single-stage gear box ratio design that operates generator at 3600 rpm for longer life, quieter operation, and smoother running.  This unit is the same as and replaces the Winpower WP50PTOS.

* Brush type rotating field two pole alternator with 100% copper windings.

* Large frequency meter viewable from tractor seat assists in setting tractor speed and monitors output.
* Capacitor voltage regulator maintains output voltage to approximately +10%.

* Rugged cast iron helical gear case with a 1-1/8" keyed 540 rpm input shaft.
* Safety shield for pto connection.

Accessories (order separately)
* adaptor to convert keyed shaft to 1-3/8" spline.
* 1-3/8" six spline to 1-1/8" slotted pto shaft is fully guarded for safety.

* Two-wheel transport offers heavy 5/16" gauge hitch that can handle the rigors of
   generator operation.
