forward or backward. Pivoting on one stopped wheel can
damage turf. This is especially important when mowing.
Tractor performance is maximum when the throttle is set at
full rpm. This gives maximum power to the drive wheels and
deck when needed. Use the control levers to control ground
speed rather than engine rpm.
Keep blades sharp. Many professional mowing companies
have additional sets of blades and change blades twice a day:
once in the morning and again at noon. Many problems with
incorrect cutting patterns are due to dull blades or blades which
have been sharpened incorrectly. Information on sharpening
blades is listed in this manual's maintenance section.
addition, most communities have individuals or companies
which specialize in sharpening mower blades. Blade sharpness
should be checked daily.
DANGER: Never work with blades while engine is
running or deck clutch switch is engaged (on).
Always place deck clutch switch in the disengaged
position, place control levers in the park brake posi-
tion and turn engine off and disconnect negative bat-
tery cable. Block up mower when you must work
under it. Wear gloves when handling blades. Always
check for blade damage if mower strikes rock,
branch or other foreign object during mowing!
Use high blade speed. Your mower is designed to operate at
full throttle. The throttle setting directly controls blade speed.
The highest blade speed generally gives best cut.
Direct grass discharge to right, away from unmown area.
Select a mowing pattern that directs grass discharge towards the
outside, not towards center, of mowing area. Generally, this
means using a pattern utilizing left turns because side discharge
is to right. In any case, avoid throwing grass discharge onto
unmowed area because grass is then mowed "twice". Mowing
twice puts an unnecessary load on the unit and reduces mowing
efficiency.
When mowing a lawn for the first time cut grass slightly
longer than normal to avoid scalping uneven terrain. When
possible, it is best to use the cutting height that was used in the
past. When cutting grass taller than six inches, you may want to
mow the lawn twice to achieve a better quality of cut.
During normal mowing cut only about 1/3 of the grass
blade. Cutting more than that is not recommended unless grass
is sparse or it is the end of the mowing season.
Alternate mowing direction to keep the grass growing
straight and better dispersion of the clippings.
Remember, grass grows at different rates at different time
of the year. Mow more often in the early spring to maintain the
same cutting height. As the growth rate slows in mid summer,
mow less frequently. If you cannot mow at a regular interval,
mow at a high cutting height; then mow again two days later at a
lower cutting height.
Raise the cutting height of the mower if the cutting width of
the mower is wider than the previous mower. This ensures that
uneven turf is not cut too short.
Raise the cutting height of the mower if the grass if slightly
taller than normal or if it contains a high degree of moisture.
Then mow it again with the cutting height set lower.
