MOWING TIPS

  CAUTION:

  Do not use de-thatcher 

blade attachments on your mower. Such 
attachments are hazardous, will damage 
your mower and could void your warranty.
•   Under certain conditions, such as very 

tall grass, it may be nec es sary to raise 
the height of cut to reduce pushing 
effort and to keep from overloading the 
engine and leaving clumps of grass clip-
pings. It may also be necessary to re-
 duce ground speed and/or run the lawn 
mower over the area a sec ond time.

•   For extremely heavy cutting, re duce the 

width of cut by over lap ping previously 
cut path and mow slowly.

•   For better grass bagging and most cut-

ting conditions, the engine speed should 
be set in the FAST po si tion.

•   When using a rear discharge lawn 

mower in moist, heavy grass, clumps 
of cut grass may not enter the grass 
catcher. Reduce ground speed (pushing 
speed) and/or run the lawn mower over 
the area a second time.

•   If a trail of clippings is left on the right 

side of a rear discharge mow er, mow in 
a clockwise direction with a small over-
lap to collect the clippings on the next  
pass.

•   Pores in cloth grass catchers can be-

come fi lled with dirt and dust with use 
and catchers will collect less grass. To 
prevent this, reg u lar ly hose catcher off 
with water and let dry before using.

•   Keep top of engine around starter clear 

and clean of grass clippings and chaff. 
This will help engine air fl ow and extend 
engine life. 

MULCHING MOWING TIPS
IMPORTANT

:  For best performance, 

keep mower housing free of built-up 
grass and trash. See “CLEANING” in the 
Maintenance section of this manual.
•  The special mulching blade will recut 

the grass clip pings many times and 
reduce them in size so that as they fall 
onto the lawn they will disperse into 
the grass and not be noticed.  Also, the 
mulched grass will bio de grade quick ly 
to provide nu tri ents for the lawn.  Always 
mulch with your highest engine (blade) 
speed as this will provide the best recut-
ting action of the blades.

•  Avoid cutting your lawn when it is wet.  

Wet grass tends to form clumps and 
in ter feres with the mulch ing action.  The 
best time to mow your lawn is the early 
afternoon.  At this time the grass has 
dried, yet the newly cut area will not be 
exposed to direct sunlight.

•  For best results, adjust the lawn mower 

cutting height so that the lawn mower 
cuts off only the top one-third of the 
grass blades.  If the lawn is over grown it 
will be nec es sary to raise the height of 
cut to reduce pushing effort and to keep 
from over load ing the engine and leaving 
clumps of mulched grass. For ex tremely 
heavy grass, reduce your width of cut 
by overlapping previously cut path and 
mow slowly.

•  Certain types of grass and grass 

con di tions may re quire that an area be 
mulched a second time to com pletely 
hide the clip pings.  When doing a sec-
 ond cut, mow across (perpendicular) to 
the fi rst cut path.

•  Change your cutting pattern from week 

to week.  Mow north to south one week 
then change to east to west the next 
week.  This will help prevent matting and 
graining of the lawn.
