Adjusting the Deck Wheels
WARNING
Keep hands and feet away from the discharge opening of the cutting deck.
NOTE:
The deck wheels are an anti-scalp feature of the deck and are not designed to
support the weight of the deck.
The deck wheels should be approximately 1⁄4-1⁄2” (6.35-12.7mm) above the ground
when the deck is set in the desired height setting. To adjust the deck wheels see the
Assembly section for instructions.
Service
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 brake pedal is completely
depressed, or if the tractor’s rear wheels can roll with the parking brake applied
(and the hydrostatic relief valve open), the brake is in need of adjustment. See your
authorized service dealer to have the brake adjusted.
Hydrostatic Neutral Adjustment
If the tractor creeps forward or rearward when neither the forward nor reverse
pedal is depressed, contact your local authorized dealer to have the neutral setting
properly adjusted.
Wheel Alignment
If your tractor pulls to one side or is out of alignment, a wheel alignment might be
necessary. Contact an authorized service dealer to have the wheels properly aligned.
Deck Removal
WARNING
Use caution to avoid pinching your fingers when rolling the belt off the PTO
pulley.
