For the best resuits do not cut wet grass because
it tends to
Stick to the underside of the mower,
thus preventing proper discharge of grass clip­
pings. If wet grass must be cut, reduce walking
speed to help distribute the ciippings more effec­
tively.
New grass should be treated as wet grass, other­
wise 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
the lawn. 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.
Lawn should be cut in the fall as long as there is
growth.
