MTD 113-120A - Manual (Page 9)

For best results, do not cut wet grass because it
tends to stick to the underside of the mower,
preventing proper discharge of grass clippings,
and could cause you to slip and fall. New grass,
thick grass or wet grass may require a narrower
cut. Blade speed should be adjusted to the condi­
tion of the lawn.
The best mowing pattern is one that allows the
clippings to discharge towards the uncut part of
the iawn. This permits recutting of the clippings
to further pulverize them. When cutting high
weeds, discharge towards cut portion, then recut
at right angies to first direction.
For best resuits, cut off one-third or less of the
total length of the grass. Lawn should be cut in
the fall as long as there is growth.
This mower is designed to be operated at full
throttle to give you the best cut and do the most
effective job of bagging the cut grass.
IMPORTANT
If you strike a foreign object, stop
the engine. Remove wire from spark
plug, thoroughly inspect the mower
for any damage, and repair the
damage before restarting and
operating the mower. Extensive
vibration of the mower during opera­
tion is an indication of damage. The
unit should be promptly inspected
and repaired.
ADJUSTMENTS
A
CAUTION
Do not at any time make any adjust­
ment to lawn mower without first
stopping engine and disconnecting
spark plug wire.
CUTTING HEIGHT ADJUSTMENT
Units With Height Adjustment Brackets
An adjusting plate and thumb lever at each wheel
provides cutting height adjustment. Each ad­
justing plate hais five height positions. Height of
cut will be changed when the thumb lever is
moved from one position to another. Simply
depress thumb lever towards wheel and move
wheel and lever assembly to desired position. All
wheels must be placed in the same relative posi­
tion.
Units Without Height Adjustment Brackets
Adjustment may be made by removing and moving
axle bolts to desired position. Cutting heights will
be raised as axle bolts are moved to a lower hole
and lowered as axle bolts are moved to a higher
hole in the deck. All axle bolts must be mounted in
the same relative position. Belleville washers
must be assembled so that the cupped side of the
washers are against the deck.
THROTTLE
If adjustment becomes necessary, the throttle
control wire assembly can be reset as follows:
1. Loosen, but do not remove, screw securing
throttle control wire assembly at engine. See
figure 7.
2. Move throttle control lever on handle to
“FAST” position.
3. Move control lever on engine to full open posi­
tion. Retighten screw to secure throttle con­
trol wire assembly.
CARBURETOR ADJUSTMENTS
\ WARNING ^
If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
Refer to the separate engine manual packed with
your mower for carburetor adjustment informa­
tion.
LUBRICATION
IMPORTANT
Always stop engine and disconnect
spark plug wire before cleaning,
lubricating or doing any kind of
work on lawn mower.
Blade Control—Lubricate the pivot points on the
blade control handle and the brake cable at least
once a season with light oil. See figure 15. The
blade control must operate freely in both direc­
tions.
