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 61).  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 (E).

Adjusting the Mower Belt Idler Spring Length
 1.  Loosen the jam nut (C) on the anchor eyebolt (B).

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 62) 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.
