Troubleshooting
Check the Mower Belt Idler 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.  Use the Mower Belt Idler Spring Length chart to 
determine the correct spring length.
 4.  Measure the coil length of the mower belt tension 
spring (A, Figure 50). The measurement should 
equal the measurement as designated in the 
chart. If the measurement does not equal the 
measurement as designated in the chart, adjust 
the anchor eyebolt (B).
Adjusting the Mower Belt Idler Spring Length
 1.  Loosen the jam nut (C, Figure 50).
 2.  Turn the adjustment nut (D) until the measurement 
as designated in the chart is achieved.
