Troubleshooting, Adjustment & Repair
Check the Mower Belt Tensioner Spring Length
1. Park the machine on a smooth level surface such
as a concrete floor. Disengage the PTO, engage
the parking brake, turn off the engine and remove
the ignition key.
2. Lower the mower deck to its lowest cutting
position.
3. Measure the coil length of the mower belt
tensioner spring (A, Figure 58). The measurement
should equal the measurement as indicated in
the chart. If the measurement does not equal the
measurement as indicated in the chart, adjust the
mower belt idler spring length.
Adjusting the Mower Belt Idler Spring Length
1. Loosen the jam nut (C).
2. Turn the adjustment nut (D) until the measurement
as designated in the chart is achieved.
3. Retighten the jam nut.

Deck Shut Down Module
This unit is equipped with a deck shut down module
that will automatically shut down the mower deck if the
engine looses oil pressure or begins to overheat.
What to do if the deck shuts down during
operation:
• Immediately check your dash panel to see if the
oil pressure indicator lamp (A, Figure 59) is lit or
the water temperature gauge (B) is reading a high
temperature.
If the oil pressure indicator lamp is lit:
• Shut the unit off immediately and see your dealer.
If the water temperature gauge reads a high
temperature:
• Move the ground speed control levers to the
neutral position, disengage the PTO switch,
engage the parking brake and reduce to half
throttle speed. Leave the engine running so the
radiator fan will continue to run and coolant will
continue to circulate.
• Check the engine coolant level. See Check Engine
Coolant Level. Add coolant if necessary.
• Check to see if the radiator screen is dirty or
plugged. See Clean Radiator & Screen. Clean
radiator screen if necessary.
• If these procedures do not cause the engine to
begin to cool down, shut the unit off and see your
dealer.
After the Problem has been resolved:
• The PTO switch must be disengaged before it can
be re-engaged.
