This manual covers the latest compact portable tractor driven Power Take Off (PTO) generator model from Winco.
This 15,000 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 and brushless, heavy-duty 3600 rpm, 2 pole, low waveform distortion
generators.
This compact PTO generator unit is designed to provide reliable electrical power for customers who already have a
compact utility tractor with 24 to 40 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 field 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 field 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 specifications.
This generator may be mounted in many different fashions.
The three most popular are foundation mounted, trailer mount
or 3-point 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, 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.

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 10 degrees during generator
operation, even though the mechanical design of the tumbling bar would allow greater misalignment.

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 mechanical design of the tumbling bar would allow greater misalignment.
D. The generator mounting area of the trailer bed should be
flat.
B. The foundation must be solid enough to absorb generator
starting and reflected load torque during operation.
C. The foundation surface should be flat.
D. Space is required around the generator for mounting
switching devices, making connections, and for servicing.
E. The generator mounting bracket must rest evenly and
firmly on the foundation. Install shims if necessary to even
out the foundation under the mounting pads then bolt the
generator firmly in place.
TRAILER MOUNTING
Mount the generator on a trailer if you plan to use it as a
portable power source. When selecting or building a trailer to
mount the generator, consider the following points:
A. The trailer construction must be strong enough to support
the generator.
B. The design of the trailer must enable the trailer to remain
stable during operation, and to resist tipping caused by
generator starting and reflected load torque.
WARNING: Personal Injury & Equipment Damage
TRAILER MAY TIP OVER AND CAUSE INJURIES IF
WHEELS ARE NOT SPACED FAR ENOUGH APART.
All four generator mounting pads must rest firmly on the trailer
bed. Install shims if necessary to even out the bed under the
mounting pads, then bolt the generator firmly in place.
WINCO THREE POINT HITCH
Optional 3-Point Hitch Part Number TPH240
WARNING: Personal Injury & Equipment Damage
WHEN USING THE 3-POINT HITCH ASSEMBLY ALL THREE
POINTS MUST BE ATTACHED TO THE TRACTOR. FAILURE TO DO SO WILL CAUSE THE GENERATOR TO TIP
WHEN LIFTING IT DAMAGING BOTH THE T-BAR AND THE
GENERATOR.
Optional Trailer Part Number TDM75
C. The trailer height and mounting position of the generator on
0310-00
A. The three point hitch must be attached to the tractor at all
times during operation.
B. When operating the generator the three point hitch and
generator must be sitting on flat level ground. All four deck
pads must be in constant contact with the ground at all
times. This will reduce the vibration in both the generator
and the tumbling bar.
C. For safety the generator must be bolted to the three point
hitch deck using all four mounting bolts
