•
Under heavier conditions it may be necessary to
raise the deck to cut the area; then re-cut the area a
second time at the lower deck setting to get a clean
cut.
•
Do NOT attempt to mow heavy brush and weeds
and extremely tall grass. Your tractor is designed to
mow lawns, NOT clear brush.
•
Keep the blades sharp and replace the blades
when worn. Refer to
Cutting Blades
on page 24 of this
manual for proper blade sharpening instructions.
Mulching
The mulching feature incorporates special blades (stan-
dard on your tractor) in a process of repeatedly re-cutting
grass clippings beneath the cutting deck. The ultra-fine
clippings are then blown back into the lawn where they
act as a natural fertilizer. Observe the following points for
the best results when mulching.
NOTE:
It is not necessary to remove the discharge
chute to operate the mower with the mulch kit installed.
However, accumulations of dried grass clippings inside
the deck’s discharge chute will interfere with insertion of
the mulch plug. If necessary, clean the discharge chute
prior to inserting the mulch plug.
•
Never attempt to mulch if the lawn is damp. Wet
grass tends to stick to the underside of the cutting
deck preventing proper mulching of the clippings.
•
Do NOT attempt to mulch more than 1/3 the total
height of the grass or approximately 1-1/2 inches.
Doing so will cause the clippings to clump up
beneath the deck and not be mulched effectively.
•
Maintain a slow ground speed to allow the grass
clippings more time to effectively be mulched.
•
Always position the throttle control lever in the
FAST (rabbit) position and allow it to remain there
while mowing. Failing to keep the engine at full
throttle places strain on the tractor’s engine and
does not allow the blades to properly mulch grass.
To operate the cutting deck without mulching, simply
remove the plastic wing nut and push the machine
screw downward through the deck while withdrawing
the mulching plug. Refer to Figure 11.

SECTION 6: MAKING ADJUSTMENTS
WARNING:
Never attempt to make any
adjustments while the engine is running,
except where specified in the operator’s
manual.
WARNING:
Disconnect the spark plug
wire(s) and ground against the engine before
performing any adjustments, repairs or
maintenance.
Carburetor
The carburetor is a main component of the emission
control system and should be adjusted or serviced only
by a qualified mechanic.
The carburetor’s main fuel jet is fixed. The low idle fuel
adjusting needle has only minimal adjustment and
normally does not need adjustment.
If the engine is hard to start, runs roughly, or stalls at
low idle speed, contact your Cub Cadet dealer for
carburetor service.
