POSSIBLE FAILURE / CAUSE & SOLUTION
Motor Inoperative: (Won't Run)
CAUSE:
Low Oil Level or No Oil?
SOLUTION:
Check and Correct Oil Level, If oil level was extremely Low or Empty, Pump Damage
most likely has occurred, This will also have to be checked. Repair any cause of Oil
loss before continuing.
CAUSE:
No Oil Flow to Motor? Front Pump Inoperative, No Pump Pressure reaching Motor.
SOLUTION:
Oil Level is correct but no Oil Flow to Motor. Check Pump connection to Tractor, Shafts,
Couplers and Adapters, make sure they are not stripped or broken. Check to make sure
Pump is "ON" if equipped with Pump "Shut Off". Check to make sure Motor is "ON"
when equipped with "Shut Off". Check for any malfunctions in Drive System and Shut
Off Components.
CAUSE:
No Voltage to Solenoid Valve? (If Equipped)
SOLUTION:
Check Fuse (if used), replace if required and try again. With Tractor Ignition Switch
"ON", and Mower Switch "ON" Test for voltage at the Solenoid Valve. A quick test is to
turn switches on (With Tractor Engine "Off") and see if a small metal object such as
a paper clip or washer will stick to the end of the Valve when the mower is turned "ON".
If it does not, The Coil is not magnetizing the Valve. Test for Voltage at the Wire using
a test Light or Voltmeter. If no Voltage is present, trace the circuit back through the
wiring, the Mower Switch, The Fuse and the Tractor Wiring to locate the faulty part.
If Current is available to the Solenoid but Solenoid won't turn on motor replace Solenoid.
CAUSE:
Spindle Locked Up?
SOLUTION:
The Spindle can be locked up causing Motor not to Start, This can usually be felt or seen
in the System trying to run but having to bypass. Sometimes the Spindle is not seized
but only tight, this can prevent motor from starting right away from a dead Stop or slowly
start, The tightness is not enough to prevent motor from running once it is started, See
the Spindle Section for more information.
Motor Over Heating:
Operating temperature exceeds 100 degrees F. over ambient Temperature).
CAUSE:
Oil Level Too Low?
SOLUTION:
Make sure it is filled to proper level with recommended Oil. Determine reason for low
Oil Level (leaks, etc.) and correct problem, Run Mower and check temperature, it
should not exceed 100 degree F. above ambient Temperature.
CAUSE:
Incorrect Oil Used?
SOLUTION:
Use recommended Hydraulic Oil, DO NOT mix Oils that are not compatible, in some
cases it may be required to drain and replace all the oil. See Specification Chart for
recommended Oil Type. When repairing unit it is recommended that Oil be update to
recommended Oil.
