･ When the screens for the air-intake openings and
radiator are clogged with dust, clean them at once.
Never go on operating with clogged screens.
･ Mowing is desirable when the grass is dew-free: in
the afternoon or late afternoon, thus preventing the
mower from heavy clogging.
･ Always keep the mower deck clean.
･ Check the blade ends for damage. (Refer to page 71.)
･ Repeated mowing is recommended before the grass
grows to high.
･ Cutting grass too closely may damage the grass. Too
maintain a green lawn, never mow more than onethird
off the height of the grass in one mowing.
･ A slower travelling speed will result in improved
mowing. Avoid selecting such a travelling speed that
causes the lawn mower to bounce.
･ Short, fast turns will damage turf. Slow down
sufficiently when turning.
･ Frequent sharpening of the mower blades results
in beautiful finishment and less load on equipment,
which leads to economical operation.
a. For mowing tall grass
i. Mow grass twice.
First, mow the grass to a height low enough for the
next finishing pass. Then finish to the desired grass
height.
The second travelling pass should be shifted sideways
by 20 cm (8 in.) or so, or travel perpendicular to the
first passes, which will result in a beautiful even finish.
ii. When trying to finish in one pass, select a sufficiently
slow travelling speed. It may also be required to set
the cutting width to half or onethird of that for normal
operation.
b. For mowing highly moist grass or on wet ground
i. If turf damage by the tyres could result, wait until the
grass and land have dried sufficiently.
ii. Wet grass requires a higher grass cutting height
setting than when mowing dry grass, as the cutting
height is often lower than expected during operation.
iii. Select a sufficiently slow travelling speed and avoid
sudden starts, turns, and stops. If not, the turf may be
damaged.
c. For mowing low molsture content grass or when
threr is much dead grass
i. Advance should be in a direction where the dust does
not hit the operator by taking into consideration the
direction of the wind.
ii. When the air-intake screens are clogged, clean them
at once.
Important:
･ When operating the lawn mower in dusty
circumstances, keep on paying attention to the coolant
temperature warning lamp.
･ Never continue operating when screens are clogged,
or engine breakdown may result.
