damage turf. This is especially important when mowing.

Mower 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.
In 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 steering control levers in the park brake position
and turn engine off and disconnect negative battery
cable. Block up mower when you

must

work under it.

Wear gloves when handling blades.

Always check for

blade damage

if mower strikes a rock, a branch or

another 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.

If the machine’s forward motion

must be stopped while

mowing, a clump of grass clippings may drop onto your lawn.
