This manual covers the latest compact portable tractor driven Power Take Off (PTO) generator model from Winco.
This 10,000 watt generator is designed to provide120/240V single phase electrical power for standby and utility service when commercial power is interrupted, inaccessible or impractical. This PTO unit has a cast iron gear case with
a 1-3/8” – 6 spline, 540 rpm rated input shaft (unit operating speed is 515 RPM) and brushless, heavy-duty 3600
rpm, 2 pole, low waveform distortion generator.
This compact PTO generator unit is designed to provide reliable electrical power for customers who already have a
compact utility tractor with 20 to 30 horsepower and a 540 rpm rated PTO shaft. The PTO unit is a cost-effective way
of providing needed electrical power without the cost or added maintenance of a dedicated drive engine. Primary applications for these PTOs are for infrequent or medium duty loads where the unit will normally be operated less than
50 to100 hours per year. Typical uses might be for farm, ranch or home standby or portable eld power away from
convenient utility or where running an extension cord is impractical. The compact PTO units are built to last, but are
not intended for prime power (continuous or sole source) applications.

DESCRIPTION
UNPACKING
The WINCO rotating eld power take-off generators are designed primarily for hobby/small farm use as a standby electrical
power supply, utilizing the power take-off of a tractor or truck
as the prime mover. This PTO drive generator will provide
120/240V single phase, 60Hz electrical service when properly
driven.
NOTE: The prime mover which drives the generator must be
capable of delivering approximately 2 HP per 1000 watts output
from the generator. Observe input RPM specications.
This generator may be mounted in many different fashions. The
three most popular are foundation mounted, trailer mount or 3point hitch mounted, for used as a standby or portable electrical
power source. Your application will dictate how you may want to
mount it.
This generator includes a color coded voltmeter to warn against
high or low voltage, and two output power receptacles with
individual circuit breakers for your protection. To reduce maintenance problems, the coupling between the generator input shaft
and rotor consists of precision helical gearing rather than a chain
link drive. The input shaft is a 1 3/8 in. diameter 6 spline shaft.
The factory thoroughly tests each generator before shipment. All
are continuous duty rated.
IMPORTANT:
THE MANUFACTURER STRONGLY RECOMMENDS RUNNING THE GENERATOR UNDER LOAD AT LEAST ONCE A
MONTH IN ORDER TO EVAPORATE ANY ACCUMULATED
MOISTURE CONDENSATION AND TO KEEP THE UNIT IN
GOOD WORKING ORDER.
CAUTION: Equipment Damage
DO NOT invert generator during unpacking. The Gearcase contains oil which will leak out if inverted during unpacking.
Unpack the generator as follows:
1. Remove the carton.
2. Examine the unit for damage.
3. Find the small subpack carton packed in the large carton. Be careful not to throw away the subpack carton
with the large carton.
4. Open the subpack carton and make sure it contains:
a. Generator instruction manual
b. Load disconnect plug (disassembled, in bag)
5. Remove the four bolts which hold the generator feet to
the pallet.
6. Lift the generator from the pallet by means of the lifting
eye on the top of the generator.
7. Inspect the generator carefully for freight loss or damage. If loss or damage is noted at time of delivery,
require that the person making the delivery make note
of the loss or damage on the freight bill, or sign the
consignee’s memo of the loss or damage. Contact the
carrier for claim procedures.
When loss or damage is noted after delivery, segregate the damaged material, and contact the carrier for claim procedures.

INSTALLATION
FOUNDATION MOUNTING
Mount the generator on a foundation if it is to be used as a
permanent or standby power source. See “TRAILER MOUNTING” or “THREE POINT HITCH MOUNTING” if generator will be
used as a portable power source. When planning a foundation
consider the following points:
A. The foundation location should enable aligning the drive
shaft (tumbling bar) in a straight or nearly straight line between
the power take-off and the generator input shaft. Misalignment
must be less than 5 degrees during generator operation, even
though the mechanical design of the tumbling bar would allow
greater misalignment.

C. The trailer height and mounting position of the generator on
the trailer should enable aligning the drive shaft (tumbling bar)
in a straight or nearly straight line between the power take-off
and generator input shafts. Misalignment must be less than 10
degrees during generator operation, even though the mechani-
cal design of the tumbling bar would allow greater misalign-
ment.
D. The generator mounting area of the trailer bed should be
flat.
