Adjusting the Select Drive Control
The Select Drive control
knob allows you to adjust the
maximum ground speed
when the Select Drive lever
is fully engaged.
Adjustment is from MIN to
MAX. With the Select Drive
lever fully engaged:
MIN
will propel the lawn
mower at its slowest speed.
MAX
will propel the lawn
mower at its fastest speed.
The position of Select Drive
knob determines the forward speed of the lawn mower, but it still
varies based on the mowing surface and terrain. For example, with
the knob in the slowest position, the mower may seem to propel
quickly on smooth concrete. However, once the mower is moving
through grass, it will go slower because of the added resistance of the
grass.
Starting the Engine
Before starting, always release the Select Drive control lever so that
the mower will not move forward when you operate the starter.
1. Turn the fuel valve to the ON position (
).
2. Move the throttle lever to the
FAST position.
3. Pull the starter grip lightly until
you feel resistance, and then
pull briskly. Return the starter
grip gently.
To ensure easy restarting and
maximum performance from
the Auto Choke System, allow
the engine to run for at least
three minutes after starting a
cold engine before stopping
the engine. This minimum run
time will be longer if the temperature is below 70 °F (21 °C).
Stopping the Engine
Release the blade control lever.
1. Move the throttle lever
to the STOP position.
2. When you finish
mowing, turn the fuel
valve OFF.
3. If your mower will not
be used for 3 to 4
weeks, run the
engine’s carburetor out
of fuel. You can do this
by leaving the fuel
valve OFF, restarting
the engine and running
it until it stops. See
if you don’t plan to use your mower for a
month or more.
4. Clean your mower after each mowing; refer to “Cleaning” on
Mowing Tips
When to Mow
Most grasses should be mowed when they have grown ½ to 1 in
(12 ~ 25 mm) above their recommended height. More frequent
mowing is required for mulching than for bagging. For best mulching
results, you may need to mow the lawn twice a week during the
growing season.
Cutting Height
Consult a local nursery or lawn and garden center for cutting height
recommendations and advice about specific types of grasses and
growing conditions in your area.
Most grass has stems and leaves. If you cut off the leaves, you’ll scalp
the lawn. Let the grass recover between mowings. Your mower will
work better, and your lawn will look better.
Cutting grass that is too tall or mowing the lawn too quickly can clog
the mower deck with grass and may cause the engine to stall. If your
grass gets too tall, cut it once at the highest cutting height setting
using a slow ground speed, then mow again in 2 or 3 days. Don’t take
off more than one third of the total grass height in any one mowing, or
brown patches may develop. Cutting height adjustment is explained
on
Cutting Width
For an even lawn finish, overlap each mowing swath by a few inches.
If the grass is very tall or thick, use more overlap and a narrower
mowing swath.
Blade Speed
The blades must spin very fast to cut properly. If engine speed drops,
it could mean the engine is being overloaded by the blades trying to
cut too much grass. Mow a narrower swath, move the mower slower,
use the rear discharge chute, or raise the cutting height.
Blade Sharpness
A sharp blade cuts cleanly. A dull blade tears the grass, leaving
shredded ends that turn brown. When your blades don’t cut cleanly
anymore, have them sharpened or replaced.
Dry Grass
If the ground is too dry, mowing will stir up a lot of dust. Besides being
unpleasant to work in, too much dust will clog the air filter. If dust is a
problem, water your lawn the day before mowing. Mow when the
grass is dry to your touch, but the soil is still moist.
Wet Grass
Wet grass is slippery and can make you lose your footing. Also, wet
grass clippings will clog the mower deck and collect in clumps on the
lawn. Always wait for wet grass to dry before mowing.
Fallen Leaves
When equipped with the grass bag, your mower can be used to pick
up fallen leaves for disposal. If using the mower to bag large amounts
of fallen leaves, and not for mowing, set the cutting height adjustment
levers so the front of the mower deck is one or two settings higher
than the rear.
If you want to mulch fallen leaves into your lawn, don’t let the leaf
cover get too deep before you begin. For best results, start mulching
while grass still shows through the leaf cover. In places where fallen
leaves completely cover the grass, remove the leaves by raking, or
install a grass bag, so your mower can pick them up for disposal.
Collecting leaves while they are damp will help to control dust and
result in more effective mulching of the leaves. You can also shred
leaves using the Clip Directors; see
for details.
