IV. INSPECTION AND MAINTENANCE OF MAJOR PARTS
79
Important:
• If the blade ends have become round due to wear,
enlarged clearance between blades leave uncut
grass behind. The blade should be checked timely
and worn ones should be replaced immediately.
• Low cutting height or the operation just after soil
has been applied will wear blades rapidly. The
blades should be checked more frequently.
a. New Blade
b. Blade with rounded edge
c. Exessively worm blades
are very dangerous. So
replace such blades with
new ones at once.
c.The blade nuts should be tightened to the specified
torque with the blades chocked respectively.
Tightening torque: 1000kg•cm (72 ft•lb)
(1) Blade
Danger:
Be sure to use new bolts when changing blades.
Important:
Make sure that the blades are not in contact with
the mower deck by turning them by hand.
d. There are two kinds of blades for respective
mower decks. Be sure to install the blades in the
proper positions.
e. Connect the mower deck to the lawn mower prop-
erly, referring to the paragraph for "attaching and
detaching the mower deck" at page 68.
4. INSPECTION OF GAUGE WHEELS
As the gauge wheels are installed on the front and
rear ends of the mower, they are more vulnerable
to being hit and deformed by obstacles than any
other part. When a wheel does not turn smoothly
or is deformed, replace it with a new gauge wheel
immediately.
5. INSPECTION OF ROLLERS
Make sure that the roller turns smoothly.
(1) Roller
Important:
• When the wheels and rollers are hard to turn, dis-
assemble them and clean them.
• After re-assembly, be sure to grease them suffi-
ciently:
