Preparation(Continued)

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
