Belt Care
A damaged or worn belt may prevent the mower from self-
propelling. Periodically inspect the belt and pulley system for
damage or wear. If necessary contact an authorized Service
Center to have belt replaced.
NOTE: Several components must be removed in order to change
the mower's drive belt. See an authorized Service Center to have
belt replaced.
Drive Control Adjustment
SINGLE LEVER AND DUAL LEVER DRIVE CONTROLS
(IF EQUIPPED)
If equipped, there is an adjustment wheel located in the drive
control handle housing that is used to tighten or loosen the drive
belt. You will need to adjust the drive control if the mower does
not propel itself with the drive control engaged or if the mower's
wheels hesitate with the drive control engaged. If either of these
conditions occur, rotate adjustment wheel clockwise to tighten
cable or counterclockwise to loosen the cable. See Figure 37 for
location on Single Lever Drive Control and Figure 38 for Dual
Lever Drive Control.
