about 1/3 of the grass blade should be cut off. Cutting
below the 44 mm (1- / ") setting is not recommended
unless grass is sparse or it is late fall when grass
growth begins to slow down.
Figure 9
When cutting grass over 15 cm tall, you may want to
first mow using the highest height-of-cut setting and a
slower walking speed; then mow again at a lower
setting for best lawn appearance. If grass is too long
and leaves clumps on top of lawn, mower may plug
and cause engine to stall.
Alternate mowing direction. This helps disperse
clippings over lawn for even fertilization.
If the finished cut lawn appearance is unsatisfactory, try
one or more of the following:
Sharpen the blade.
Walk at a slower pace while mowing.
Raise the height-of-cut setting on your mower.
Cut grass more frequently.
Overlap cutting swaths instead of cutting a full swath
with each pass.
Mow across the marginal areas a second time.
Set height-of-cut on front wheels one notch lower than
rear wheels. (example: set front wheels at 44 mm
(1- / ") setting and rear wheels at 57 mm (2- / "
setting).
Cutting Leaves
When cutting is complete, always be sure that 50% of
the lawn shows through the cut leaf cover. This may
require one or more passes over the leaves.
For light leaf coverage, position all wheels at the same
height-of-cut setting.
If there are more than five inches of leaves on lawn,
set the front wheels one or two notches higher than the
rear wheels. This makes it easier to feed leaves under
mower deck.
Walk at a slower mowing speed if leaves are not being
cut up finely enough to be hidden down in the grass.
If you cut up a lot of oak leaves, you might want to
add lime to your grass in the spring. Lime reduces the
acidity of oak leaves.
Operation
Operating Tips
1. BEFORE EACH MOWING—Be sure blade brake,
m-976
self–propelled drive, and control bar function properly.
When control bar is released, blade and self-propelled
drive are designed to stop. If controls are not
functioning properly, do not use mower until controls
are repaired.
2. SHARP BLADE—Begin each cutting season with a
sharp blade. Periodically file down nicks.
Starting, Stopping, And
Self-propelling
CONTROLS (Fig. 10)—The throttle control and ground
speed control levers are on the console on the handle with
the throttle control to the left and the ground speed control
to the right. The blade/self-propelled control bar is under
the upper handle. The recoil starter is on top of engine.
1. Throttle control
2. Ground speed control
1. Push spark plug wire onto spark plug.
2. STARTING—Move ground speed control to neutral
and throttle to
primer (Fig. 15) with thumb and push once. With your
foot on the mower housing, pull the recoil starter out
until resistance is felt; then pull vigorously to start the
engine. Regulate throttle and ground speed control as
desired when engine starts.
