8 - TROUBLESHOOTING
Below are tips and guidelines for
troubleshooting some problems or concerns,
which may occur during the life of your
equipment. SHould these guidelines not solve a
problem please contact the factory for further
instruction.
Engine won’t crank.
• There are 2 electrical safety switches on
every crawler(seat safety switch and brake
pedal safety switch), and a third when the
HC74 Hydraulic Circuit option is installed.
Only the brake safety switch and the HC74
Hydraulic circuit safety switch will prevent
the tractor from cranking.
Verify the HC74 handle on the right-rear
fender is rotated completely into the OFF
position and the safety switch is depressed.
Vibration during operation can result in the
HC74 Hydraulic Circuit kit handle rotating
slightly and de-activating the safety switch.
With a conductivity meter verify both the
Brake safety switch and the HC74 Hydraulic
circuit safety switch are operating properly.
• Verify the electrical fuse is in tact.
Engine cranks but won’t start
• Verify there is adequate fuel & fuel filter is in
good condition.
• Verify seat safety switch is being engaged
and operating properly.
Engine dies when not in the seat.
• This is a normal operating characteristic to
safeguard against accidental engagement
of the tractor and/or attachments while not
properly located in the operator’s seat.
Do Not Bypass
this safety feature.
Tractor drive and/or attachments behave
erratically
.
• Verify hydraulic fluid level is within the
required operating range. Low fluid levels
can result in air intake to the hydraulic
system, which can result erratic operating
characteristics.
• Verify the large suction lines for hydraulic
pumps are properly secured by their hose
clamps. Loose suction lines can result in
air intake and erratic operation.
Track tensioning adjustment has reached its
limit, but tracks are still loose.
• It is possible to remove links from the track
chain to shorten the track loop. Contact
factory for details.
• Tracks need to be replaced.
One cylinder function of an attachment is not
responding.
• A non-functioning cylinder can result from
either a problem with the cylinder or the
valve section operating the cylinder. To
test, take the two hoses of the non-
functioning cylinder and switch their
connection at the operating valve with those
of the adjacent valve section.
• If the non-functioning cylinder continues
to not operate the cylinder is faulty.
• Should the cylinder now work, but the
cylinder of the control that was switched
stops working problem lies in the valve
section.
Tractor has little power.
• Verify engine throttle is adequate.
• Verify hydraulic fluid level is adequate.
• Verify there are not external loads draining
engine power (e.g. the PTO is operating
although not needed).
• Turn off overdrive function (MH7000 only),
or accessory (backhoe).
