6. EFFICIENT MOWING
IMPORTANT:
•
Be sure to mow at full throttle (
r
).
• Choose an adequate traveling speed in accordance
with the height or other conditions of grass to be cut.
• When the screens for the air-intake openings and radi-
ator 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.
• Repeated mowing is recommended before the grass
grows to high.
• Cutting grass too closely may damage the grass.
To 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 mow-
ing. Avoid selecting such a travelling speed that caus-
es the zero turn mower to bounce.
• Short, fast turns will damage turf. Slow down suffi-
ciently 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 to make it low enough
for the next finishing pass. Then finish to the desired
grass height.
The second travelling pass should be shifted side
ways by 20 cm (8 in.) or so, or travel perpendicu-
lar to the first passes, which will result in a beau-
tiful 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 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 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 zero turn mower in dusty circum-
stances, keep on paying attention to the coolant tem-
perature warning lamp with buzzer.
• Never continue operating when screens are clogged,
or engine breakdown may result.
