MTD 112-530 - Manual (Page 6)

When sharpening blade, follow the original angle of
of grind as a guide. It is extremely important that
each cutting edge receives an equal amount of grind­
ing to prevent an unbalanced blade. An unbalanced
blade will cause excessive vibration when rotating
at high speeds and may cause damage to the mower.
Upon reassembling, make certain all parts
assembled properly and tightened securely. are
2. Deck — The underside of mower deck should be
cleaned after each period of use as grass clippings,
leaves, dirt and other matter accumulates. This
accumulation of grass clippings, etc. is undesirable
as it will invite rust and corrosion and may cause
an uneven discharge of grass clippings at next
cutting.
The deck may be cleaned by tilting the mower back­
ward or on its right side and scraping clean with a
suitable tool or by washing with a stream of water
from a garden hose. CAUTION; Do not direct the
stream of water at a hot engine as damage to the
engine may result.

grease to prevent rusting.

floor.
e. Store mower in a dry, clean area.
USING YOUR ROTARY MOWER
For best results do not cut wet grass because it tends
to stick to the underside of the mower, thus preventing
proper discharge of grass clippings. If wet grass must
be cut, reduce engine speed to help distribute the
clippings more effectively.
New grass should be treated as wet grass, otherwise a
normal walking speed is about the right pace for
efficient mowing.
The best mowing pattern is one that allows the clippings
to discharge towards the uncut part of thé lawn. This
permits recutting of the clippings to further pulverize
them. When cutting high weeds, discharge towards cut
portion then recut at right angle to first direction.
Lawns should be cut in fall as long as there is growth.

BELT WEAR
Belt clips improperly positioned
will cause premature belt wear.
The belt clip must completely
clear the belt when the belt is
tightened. It should also assist in freeing the
belt from the blade spindle pulley when the belt
is loose. This may be checked by removing the
blade spindle cover.
