placed on the trailer and connected
with the shaft to the tractor and
generator. IMPORTANT The generator
MUST be mounted forward of the
trailer axle to prevent the trailer from
tipping backwards which can cause
personal injury or death. Once the
positioning of the generator, shaft and
relationship to the axles has been
determined, secure the generator using
4 hex bolts of at least 3/8 inch diameter
with washers and nuts. Drilling four
holes will be required. It is strongly
recommended that the axle length be
at least 41 inches before the wheel
hubs. This width is recommended to
prevent the torque required to turn the
generator from causing the generator
and trailer from tipping over. The
trailer height should enable aligning
the drive shaft in a straight or nearly
straight line between the tractor PTO
and the generator PTO. Misalignment
must be less than 10 degrees during
operation even though the mechanical
design of the shaft would allow greater
misalignment. This optional trailer can
be ordered from your local dealer.
Three Point Hitch
(Optional Accessory)3418
See figure 4 for
a typical example
of a three point hitch. Mount the three
point hitch to the tractor. Place the
generator on the three point hitch.
Attach the shaft to the generator and
the tractor PTO’s. Once the positioning
of the generator, shaft and relationship
on the three point hitch has been
determined, secure the generator using
4 hex bolts of at least 3/8 inch diameter
with washers and nuts. The height of
the generator should enable aligning
the drive shaft in a straight or nearly
straight line between the tractor PTO
and the generator PTO. Misalignment
must be less than 10 degrees during
operation even though the mechanical
design of the shaft would allow greater
misalignment.This optional hitch can be
ordered from your local dealer. Drilling
four holes will be required.
Operating The Generator
Keep the area
around the
generator clear of all debris, rags etc.
Do not smoke around the generator or
tractor. Be certain the generator is
properly grounded. Turn the main 2
pole circuit breaker on the generator to
the off position. Be certain all of the
safety guards are in place. Check the
gear box inspection plate to verify that
gear oil is up to the level of the
inspection point. Do not overfill the oil
in the gear box. Remove any weather
protective covers that may have been
put over the generator before
operating the unit. Make certain that
the generator is properly mounted on a
secure location (concrete slab, trailer or
three point hitch), no people or
children are around the generator and
plug in the electrical load into the
receptacle or full power connector.
Make certain that the tractor wheels
are blocked to prevent the tractor from
moving and the parking brake is
applied. Start the tractor and at low
idling speed engage the PTO to the
generator. Slowly bring up the speed in
the generator until the volt meter
reads at least 240 volts on the PTO
15/12 and PTO 30/25 (which is 60 hertz)
or 60 hertz on the other PTOs (which is
240 volts) and lock the tractor speed.
Lower voltage, below 240 volts or
below 60 hertz is worse than slightly
higher voltage or slightly higher
frequency. When the tractor and
generator are operating properly, turn
the isolation switch from the utility
position to the off position and then to
the generator position. Next, switch
the main 2 pole circuit breaker on the
generator
to the on position and you are now
being powered by the PTO generator.
Do not open any protective covers,
control panels, etc. while the generator
is operating.
When it is time to stop operating the
generator, you must first remove either
the electrical load from the generator
circuit breaker to the off position.
Do not slow the generator speed down
with an electrical load on the generator
or damage to the generator and load
will occur. Bring the tractor PTO speed
down to idle and shut the tractor PTO
off. You would then switch the
isolation switch back to normal
utility power.
Isolation Switch and
Isolation Circuits
See figure 5 for the proper installation
of a customer supplied isolation switch.
Installation of an
isolation switch
must be done by a licensed electrician.
Back feeding of electrical power from a
generator without a proper isolation
switch installed can kill service
personnel working on power lines
and/or damage equipment when the
utility returns normal power. See figure
5 for a sample wiring of an isolation
switch. Do not operate this generator
in parallel with another generator. The
isolation switch has three positions,
utility position, off and generator
position. The National Electrical Code
and local codes require an isolation
switch be installed between a standby
generator (such as a PTO generator)
and the utility lines. See figures 6 and 7
for Isolation Circuits.
Full Power Connector
Installation
See figures 15 and
17 . The connector
has been assembled at the factory. Only
a licensed electrician should install the
wire cables to the connector. Failure to
properly connect the wires will result in
damage to the equipment and/or
personal injury. Consult a wire
ampacity chart for the proper wire
gauge size for a given generator. You
must use stranded copper welding
cable with a 600 volt rating and a
minimum of 3AWG hypalon insulation.
The wires must be stripped about 0.75
inch from the end of the cable. Insert
the end of the wire into the open
