Mulching Tips
Mulching finely cuts the grass so that the grass can be easily
recycled. Becausethe nutrients are returnedto the soil, the
lawn will need less fertilizer. Tocorrectly mulch the lawn,
follow the tips below.
oThegrass must be dry. if the grass is wet, it will be
difficult to cut and cause heavyclumps of grass.
oThegrass must not be too tall. The maximum heightto
effectively cut is 4 1/2 inches.Set the height adjusters
so that only the top third of the grass is cut.
oif the grass is more than 4 1/2 inches high, two
mowings will be necessary.Forthe first mowing, set the
height adjusters in the highest position. Then,lower the
height adjusters for the second mowing.
o Keepa sharp edge on the blade.A bladethat is not
sharp will causethe ends of the grass to become brown.
- Cleanthe undersideof the mower housing. Grass and
other debris cankeepthe mower from working
correctly.
if the quality of cut is marginal, try the following:
oSetthe height adjusters at a higher cutting height.
, Cut the grass more frequently.
, Operatethe mower at a slower ground speed.
oOverlapthe cutting swaths instead of cutting a full
swath with each pass.
oMow across the marginal areasa second time.
Preparing the Engine
ENGINEDOESNOTCONTAINOiL ORGASOLINE
Using the bottle of oil supplied in the carton, fill the engine
with the proper amount of oil. Seethe engine manufacturer's
