Maintenance
Check the Tires
Check the air pressure in the tires. Tires with too much
air pressure will cause the unit to ride rough. Also, the
wrong air pressure will keep the mower housing from
cutting level. The correct air pressure is: Front Tires
0,97 BAR (14 PSI), Rear Tires 0,69 BAR (10 PSI).
7. Remove the adjuster nut (2) from the shifter
bracket (3). Pull the motion drive belt over the
shifter bracket (3) (see
Figure 26
).
8. To remove the motion drive belt (1) from the stack
pulley (2), pull the front end of the belt under the
stack pulley and then back between the stack
pulley and the steering plate (3) (see
Figure 34
).
9. Remove the access panel (1) (see
Figure 35
).
10. Remove the two screws (4) that attach the steering
shaft assembly. Raise the steering wheel and
steering shaft assembly. Pull the motion drive
belt (3) under the steering shaft assembly.
11. Remove the motion drive belt . A correct re-
placement part or assistance is available from
an authorized service center in your area.
