8. EFFICIENT MOWING
IMPORTANT: • Be sure to mow at full throttle (
r
).
• Choose an adequate travelling speed in
accordance with the height or other con-
ditions of grass to be cut.
• 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 after-
noon, thus preventing the mower from
heavy clogging.
• Always keep the mower deck clean.
• Check the blade ends for damage. (Refer
to page 83 and 84.)
• Repeated mowing is recommended be-
fore the grass grows to high.
• Cutting grass too closely may damage
the grass. Too maintain a green lawn,
never mow more than one-third 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 or fast turns will damage turf. Slow
down sufficiently when turning.
• Frequent sharpening of the mower
blades results in beautiful finish and less
load on equipment, which leads to eco-
nomical 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 one-third of that for normal
operation.
b. For mowing highly moist grass or on wet ground
i. If the turf damage by the tires could result, wait until
the grass and land have dried sufficiently.
ii. Wet grass requires a higher grass cutting height set-
ting 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 moisture 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.
