• Under certain conditions, such as very tall grass, it
may be necessary to raise the height of cut to reduce
pushing effort and to keep from overloading the engine
and leaving clumps of grass clippings. It may also be
necessary to reduce ground speed and/or run the lawn
mower over the area a second time.
pushing effort and to keep from overloading the engine
and leaving clumps of grass clippings. It may also be
necessary to reduce ground speed and/or run the lawn
mower over the area a second time.
• For extremely heavy cutting, reduce the width of cut
by overlapping previously cut path and mow slowly.
• For better grass bagging and most cutting conditions,
the engine speed should be set in the fast position.
• Pores in cloth grass catchers can become fi lled with dirt
and dust with use and catchers will collect less grass.
To prevent this, regularly hose catcher off with water
and let dry before using.

• 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 biode-
grade quickly to provide nutrients for the lawn. Always
mulch with your highest engine (blade) speed as this
will provide the best recutting action of the blades.
