on the front of the seat frame. See Figure 41.
NOTE: The multi-tool (if equipped) can be used to make
this adjustment.

3. To decrease the forward speed, turn the lapbar drive control
lever stop adjustment bolts (a) clockwise. To increase the
forward speed, turn the lapbar drive control lever stop
adjustment bolts (a) counter-clockwise. Turn the lapbar
drive control lever stop adjustment bolts (a) in the necessary
direction 1⁄4-turn at a time. After turning the lapbar drive
control lever stop adjustment bolts (a), check the adjustment
by driving the tractor. See Figure 41.
4. Continue the adjustment until the wheel speeds are in sync
and the tractor drives straight with the drive control levers
fully extended forward in the full-speed position.
NOTE: Make sure the bolts extend through the nuts on the frame
to engage the locking feature.

ELECTRICAL SYSTEM
A fuse is installed to protect the tractor’s electrical system from
damage caused by excessive amperage. Always use the same
capacity fuse for replacement. If the electrical system does not
function, check for a blown fuse.
If you have a recurring problem with blown fuses, have
the tractor’s electrical system checked by your authorized
service dealer.
RELAYS AND SWITCHES
There are several safety switches in the electrical system. If a
function of the safety interlock system described earlier is not
functioning properly, have the electrical system checked by your
authorized service dealer.
PARKING BRAKE ADJUSTMENT
If the tractor does not come to a complete stop when the control
levers are moved fully outward engaging the parking brake or if
the tractor’s rear wheels can roll with the parking brake engaged
(and the hydrostatic relief valve open), the brake is in need of
adjustment. See your authorized service dealer to have the
brake adjusted.
