This manual covers the latest compact portable tractor driven Power Take Off (PTO) generator set 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 interrupted, inaccessible or impractical. This PTO unit has a cast iron gear cases with
a 1-3/8” – 6 spline, 540 rpm input shafts and brushless, heavy-duty 3600 rpm, 2 pole, low waveform distortion generators.
This compact PTO generator units 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 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.

INTRODUCTION
The words generator and alternator are used interchangeably but have the same meaning.
This manual covers standby generators driven by the
power take-off of a compact tractor. This generator
use a external voltage regulator excitation system. All
generators are carefully inspected, tested and packaged for shipment at the factory. The generator should
be unpacked as early as possible upon receipt and
inspected for damage which may have occurred during
shipment. Any damage noted should be promptly
reported to the carrier in order that a claim can be filed
to recover the cost of the damage. If at all possible,
this damage should be noted on the freight bill at the
time of delivery. If the damage appears to be of a
major nature, the generator should not be operated
until the fault has been corrected.
Tractor driven generators are designed to deliver
voltage and current similar to that of the normal power
line. Equipment that can be operated on normal power
can also be operated by the generator, provided that
the capacity of the generator is not exceeded. It
should be remembered that the power line, for all
practical purposes, is backed by an unlimited generator.
When not in use the generator should be stored in a
clean dry location. All types of mechanical equipment
suffer from long periods of storage without use. The
generator should be used at frequent intervals to
prevent deterioration and detect possible fault before
an emergency condition develops.
SAFETY INFORMATION
This generator set has been designed and manufactured to allow safe, reliable performance. Poor maintenance, improper or careless use can result in potential
deadly hazards; from electrical shock, exhaust gas
asphyxiation, or fire. Please read all safety instructions
carefully before installation or use. Keep these instructions handy for future reference. Take special note
and follow all warnings on the unit labels and in the
manuals.

hand or your foot.
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” if generator will be used as a portable power
source (Figure 1). 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.
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.All four generator mounting pads must rest 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. See Figure 1. 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.
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 mechanical
design of the tumbling bar would allow greater misalignment.
D.The generator mounting area of the trailer bed should
be flat.

OPERATING THE ALTERNATOR
WARNING: Personal Injury
When working on or around these generators, do not
wear loose fitting clothing or any articles that may
get caught in moving parts.
A properly rated and installed double throw manual
power isolation transfer switch must be used with a
standby generator. The transfer switch isolates the load
from the power line and allows you to safely operate your
loads without endangering the power line repair crew.
