46” Models Only:
 1.  Pull the lever (A, Figure 43) towards the rear of 
the machine to release tension on the mower belt.  
Remove the belt from the PTO pulley (C, Figure 
44).
 2.  Remove the old drive belt and install the new one 
as shown in Figure 44.  Note that the back on the 
drive belt must ride against the back-side idler 
pulleys (B).  Use the belt tension lever (A, Figure 
44) to release the tension on the idler pulley for 
installation.
54” Models Only:
 1.  Using a 1/2” breaker bar, place the square end in 
the square hole located in the idler arm (A, Figure 
45).  Carefully rotate the breaker bar COUNTER-
CLOCKWISE, which will relieve the tension on the 
belt exerted from the idler arm.  Slide the belt off 
the stationary idler pulley (B).
 2.  Remove the old drive belt and install the new one 
as shown in Figure 46.  Make sure that the V-side 
of the belt runs in the pulley groves of the spindle 
pulleys, and that the back of the drive belt must 
ride against the back-side idler pulleys (B).
 3.  Install the belt on the PTO pulley, the spindle 
pulleys and all the idler pulleys except the 
stationary idler pulley (B, Figure 46).  Carefully 
rotate the breaker bar COUNTER-CLOCKWISE 
and install the belt on the stationary idler pulley.
WARNING
Use extreme caution when rotating the idler 
arm with the breaker bar, due to increased 
tension in the spring as the idler arm is being 
rotated.  Injury may result if the breaker bar is 
prematurely released while the spring is under 
tension.
