e. Shift the lift lever to the DOWN (
d
) position in order
to lower the mower deck.
CAUTION: Before operating the lift lever,
be seated on the operator’s seat and make
sure of the safety conditions around the
front mower.
4. INSPECTION OF GAUGE WHEELS
As the gauge wheels are installed on the front end of the
mower, they are vulnerable to being hit and deformed
by obstacles. When a wheel does not turn smoothly or
is deformed, replace it with a new gauge wheel immedi-
ately.
5. INSPECTION OF ROLLERS
Make sure that the front roller and rear rollers turn
smoothly.
(1) Front roller (2) Rear rollers
IMPORTANT:
・
When the wheels and rollers are hard to turn, disas-
semble them and clean them.
・
After re-assembly, be sure to grease them sufficiently.
6. CLEANING OF MOWER DECK
a. Remove each belt cover and drive-shaft cover, and
clear the grass and dust accumulated under the
cover before operation. Otherwise a shorter service
life of the belts and damage to bearings and oil
seals will be caused.
b. Install a new blade, insert the washer and tighten
blade nuts temporarily to determine the height differ-
ence between blades. If it is more than 2 mm (0.08
inch), correct it with adjusting shims. The clearance
should be measured in all cases: original position
and the position with the blades respectively turned
by 180 degrees.
Excessive difference in blade positioning will result
in poor mowing finish.
(1) Shim
c. The blade nuts should be tightened to the speci-fied
torque with the blades chocked respectively.
Tightening torque: 1000 kg ・ cm (94 ft ・ lb)
DANGER: Be sure to use new nuts when
changing blades.
(1) Blade (2) Washer
IMPORTANT: Make sure that the blades are not in
contact with the mower deck by turning
them by hand.
d. While lifting up the mower deck in the center, turn it
back to the original position.
