MTD 113-080A - Manual (Page 11)

For best results, 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 has nine 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
wheel and lever assembly to desired position
wheels must be placed in the same relative posi­
tion. See figure 19. mo^ve
All
FIGURE 19.
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 on the inside and outside of
the deck so that the cupped side of the washers
are against the deck. The spacers (on units so
equipped) must be assembled between the rear
wheels and the belleville washers. Refer to figures
13 and 14.
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 9.
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 t
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 fuei, temperature,
altitude and load.
Refer to the separate engine manuai 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 20. The
blade control must operate freely in both direc­
tions.
