A worn spindle belt will affect the quality of cut from the mower deck and should be replaced. Referring to Figure 23, replace the spindle belt as follows:
Remove Spindle Belt
•Remove the two hex screws securing the LH belt cover to the deck. Slide the belt cover tabs from the slots of the deck index bracket to remove the cover. Refer to Figure 20
•Remove the three hex cap screws securing the RH belt cover and remove the belt cover.
•Observe the routing of the spindle belt to help ensure proper installation of the new belt.
WARNING!: The idler arm and movable flat idler pulley are under spring tension. Use caution when handling the idler pulley.
•Push the movable flat idler pulley toward the left side of the deck to relieve belt tension. Slip the spindle belt up and off the movable flat idler pulley, then carefully release the flat idler pulley.
•Slide the belt off and over the LH spindle pulley, then pull the belt under the LH belt cover mounting bracket. See Figure 23.
•Slip the belt off the fixed flat idler pulley, center spindle pulley, and RH spindle pulley.
•Remove the four hex cap screws securing the gear box to the gear box mounting bracket on the deck.

•Lift the gear box, slip the belt off and underneath the drive pulley, and remove the belt from the deck.
Install New Spindle Belt
•Lift the gear box assembly to install the belt around the drive pulley.
•Position the gear box to align its four screw holes with the gear box mounting bracket holes. Secure with the four hex cap screws removed earlier.
•Route the backside of the belt around the back and right of the movable flat idler pulley as shown in Figure 23.
•Loop the belt and route in front of the shoulder bolt toward the left side of the deck. Slide the loop of the belt underneath the LH belt cover mounting bracket, and place the belt in the groove of the LH spindle pulley. See Figure 23.
•Then route the belt as follows:
1.Around the rear of the fixed flat idler pulley
2.Around the front of the center spindle pulley
3.To the right spindle pulley
•After making certain the spindle belt is properly engaged in each pulley and that the backside of the belt is against the shoulder bolt, pivot the movable flat idler pulley toward the left side of the deck to relieve tension and to allow the belt to be rolled onto the right hand spindle pulley.
•Install the belt covers and secure with the hex cap screws.
