MAINTENANCE Park Brake Deck Lift Spring When mowing 2" (5.1 cm) or lower, it may be necessary to adjust the deck lift springs. Access the springs by tilting the seat forward. Loosen the nut to adjust the spring tension. Neutral Adjustment Perform the adjustment with the machine parked on level ground and the park brake engaged. 1. Raise the rear wheels of the machine and support it with jack stands. 2. Start the engine. If the either wheel turns while the machine's park brake is engaged, the neutral linkage for the corresponding wheel must be adjusted. 3. To access the control rod linkage, unlatch and rotate the seat forward. WARNING! Faulty adjustment will result in reduced braking and can cause an accident. Visually check that no damage is found on the steering control levers, links or switches belonging to the park brake. Do a standstill test and check that there is sufficient braking action. 1. Make equal adjustments on the two park brake controls.To make adjustments, remove the rivet pins from the boot and slide the boot up. 2. If the park brake position does not pass the standstill test, or has needed maintenance, it may need adjustment. The spring should measure a compressed length of 1/2" (12.7 mm) shorter than the free length. Tighten the nuts holding the brake spring if necessary. 3. To change the park brake action, tighten the pivot bolt until the desired braking feel is correct. 4. Remove and retain the pin from the front coupler. 5. Turn the hex nut by hand in either direction until the wheel stops turning. 6. Turn the hex again, counting the number of turns with the flat surfaces of the nut. Stop turning when the wheel spins in the opposite direction. 7. Turn the nut back, one half of the amount of turns counted in Step 6. 8. Repeat with the opposite wheel if necessary. Tire Pressures All tires must be at 15 psi / 103 kPa / 1 bar. IMPORTANT INFORMATION DO NOT add a tire liner or foam fill material to the tires. Excessive loads created by foam filled tires will cause premature failures. Only use O.E.M. specified tires. 25

Tire Pressures
All tires must be at 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION
DO NOT add
a tire liner or foam fill material to the tires.
Excessive loads created by foam filled tires will
cause premature failures.
Only use O.E.M. specified tires.
Deck Lift Spring
When mowing 2" (5.1 cm) or lower, it may be
necessary to adjust the deck lift springs. Access
the springs by tilting the seat forward. Loosen the
nut to adjust the spring tension.
Park Brake
WARNING
!
Faulty adjustment will result
in reduced braking and can cause an accident.
Visually check that no damage is found on the
steering control levers, links or switches belonging
to the park brake. Do a standstill test and check
that there is sufficient braking action.
1. Make equal adjustments on the two park
brake controls.To make adjustments, remove
the rivet pins from the boot and slide the boot
up.
2. If the park brake position does not pass the
standstill test, or has needed maintenance,
it may need adjustment. The spring should
measure a compressed length of 1/2" (12.7
mm) shorter than the free length. Tighten the
nuts holding the brake spring if necessary.
3. To change the park brake action, tighten
the pivot bolt until the desired braking feel is
correct.
Neutral Adjustment
Perform the adjustment with the machine parked
on level ground and the park brake engaged.
1.
Raise the rear wheels of the machine and
support it with jack stands.
2. Start the engine. If the either wheel turns while
the machine's park brake is engaged, the
neutral linkage for the corresponding wheel
must be adjusted.
3. To access the control rod linkage, unlatch and
rotate the seat forward.
