Adjustment - MTD 11A-433E500 Owner's Manual

Disconnect and ground the spark plug wire
•
as instructed in the separate engine manual
to prevent accidental starting while equip-
ment is unattended.
To remove the mulching kit, simply lift up rear
discharge door and remove the rear mulching
plug. See figure 12. Then attach the grass
catcher (optional equipment).
WARNING: Your mower is designed
to cut normal residential grass of a
height no more than 10". Do not at-
tempt to mow through unusually tall,
dry grass (e.g., pasture) or piles of
dry leaves. Debris may build up on
the mower deck or contact the engine
exhaust presenting a potential fire
hazard.
FOR THE BEST RESULTS WHEN MULCHING:
Clear lawn of debris. Be sure that the lawn is
•
clear of stones, sticks, wire or other foreign ob-
jects which could damage the lawnmower.
Such objects could be accidentally thrown out
by the mower in any direction and cause seri-
ous personal injury to the operator and others
as well as damage to property and surrounding
objects.
Do not cut wet grass. For effective mulching
•
do not cut wet grass because it tends to stick to
the underside of the deck preventing proper
mulching of the grass clippings.
Cut no more than 1/3 the length of the grass.
•
The recommended cut for mulching is 1/3 the
length of the grass. Ground speed will need to
be adjusted so the clippings can be dispersed
evenly into the lawn. For especially heavy cut-
ting in thick grass it may be necessary to use
one of the slowest speeds in order to get a
clean well mulched cut. When mulching long
grass you may have to cut the lawn in two
passes, lowering the blade another 1/3 of the
length for the second cut and perhaps cutting in
a different pattern than was used the first time.
Overlapping the cut a little on each pass will
also help to clean up any stray clippings left on
the lawn. The mower should always be oper-
ated at full throttle to get the best cut and allow
it to do the most effective job of mulching.
Clean underside of deck. Be certain to clean
•
the underside of the cutting deck after each use
to avoid a build-up of grass, which would pre-
vent proper mulching.
Mulching Leaves. The mulching of leaves can
•
also be beneficial to your lawn. When mulching
leaves make sure they are dry and are not lay-
ing too thick on the lawn. Do not wait for all the
leaves to be off the trees before you mulch.
It is recommended keeping driveways and side-
•
walks on the operators right while moving.
Continue mowing using this pattern, having the
left side of your lawnmower next to the uncut
grass. Mulching with the cutting area of the
mower on the lawn avoids grass clippings in
undesirable areas.
WARNING: If you strike a foreign ob-
ject, stop the engine. Remove wire
from spark plug, thoroughly inspect
the mower for any damage, and repair
the damage before restarting and op-
erating the mower. Extensive vibration
of the mower during operation is an
indication of damage. The unit should
be promptly inspected and repaired.
DECK
The underside of the mower deck should be
cleaned after each use to prevent a buildup of
grass clippings, leaves, dirt or other matter. If
this debris is allowed to accumulate, it will invite
rust and corrosion, and may prevent proper
mulching.
The deck may be cleaned by tilting the mower
and scraping clean with a suitable tool (make
certain the spark plug wire is disconnected).

the best for most mow-
ers.
To change the height of

moving up or down to selected height.
NOTE: All wheels must be in the same
height of cut.
