WARNING: Your mower is de signed to cut
nor mal res i den tial grass of a height no more
than 10". Do not at tempt to mow through un -
usu ally tall, dry grass (e.g., pas ture) or piles
of dry leaves. De
bris may build up on the
mower deck or con tact the en gine ex haust
pre sent ing a po ten tial fire haz ard.
For the best results when mulching:
• Clear lawn of de bris. Be sure that the lawn is clear
of stones, sticks, wire or other for eign ob jects which
could dam
age the lawnmower. Such ob jects could
be ac ci den tally thrown out by the mower in any di -
rec
tion and cause se ri ous per sonal in jury to the
op er a tor and oth ers as well as dam age to prop erty
and sur round ing ob jects.
•
Do not cut wet grass. For ef fec tive mulch ing do not
cut wet grass be cause it tends to stick to the un der -
side of the deck pre vent ing proper mulch ing of the
grass clip pings.
• Cut no more than 1/3 the length of the grass. The
rec om mended cut for mulch ing is 1/3 the length of
the grass. Ground speed will need to be ad justed so
the clip pings can be dis persed evenly into the lawn.
For es pe cially heavy cut ting in thick grass it may be
nec es sary to use one of the slow est speeds in or der
to get a clean well mulched cut. When mulch ing long
grass you may have to cut the lawn in two passes,
low er ing the blade an other 1/3 of the length for the
sec ond cut and per haps cut ting in a dif fer ent pat tern
than was used the first time. Over lapping the cut a lit -
tle on each pass will also help to clean up any stray
clip pings left on the lawn. The mower should al ways
be op er ated at full throt tle to get the best cut and al -
low it to do the most ef fec tive job of mulch ing.
• Clean un der side of deck. Be cer tain to clean the
un der side of the cut ting deck af ter each use to avoid
a build-up of grass, which would pre
vent proper
mulch ing.
•
Mulching Leaves. The mulch ing of leaves can also
be ben
e fi cial to your lawn. When mulch ing 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 be fore you mulch.
• It is rec om mended keep ing drive ways and side walks
on the op er a tors right while mov ing. Con tinue mow -
ing us
ing this pat tern, hav ing the left side of your
lawnmower next to the un cut grass. Mulching with
the cut ting area of the mower on the lawn avoids
grass clip pings in un de sir able ar eas.

thor oughly in spect the mower for any dam -
age, and re pair the dam age be fore re start ing
