Figure 16

1. Rear deﬂector

2. Insert the grass bag handle onto the notches on the

handle brackets (Figure 17).

– Walk at a slower pace while mowing.

– Raise the cutting height on your mower.

– Cut the grass more frequently.

Removing the Grass Bag

1. Lift up the rear deﬂector (Figure 17).

2. Lift the grass bag handle out from the notches on the

handle brackets and remove the bag from the mower.

– Overlap cutting swaths instead of cutting a full

swath with each pass.

3. Close the rear deﬂector.

– Set the cutting height on the front wheels one

notch lower than the rear wheels. For example,

set the front wheels at 2 inches (51 mm) and the

rear wheels at 2-1/2 inches (64 mm).

Operating Tips

General Mowing Tips

• Clear the area of sticks, stones, wire, branches, and

other debris that the blade could hit.

Cutting Leaves

• After cutting the lawn, ensure that half of the lawn

shows through the cut leaf cover. You may need to

make more than one pass over the leaves.

• Avoid striking solid objects with the blade. Never

deliberately mow over any object.

• If the mower strikes an object or starts to vibrate,

immediately stop the engine, disconnect the wire

from the spark plug, and examine the mower for

damage.

• If there are more than 5 inches (13 cm) of leaves

on the lawn, set the front cutting height one or two

notches higher than the rear cutting height.

• For best performance, install a new blade before the

cutting season begins.

• Slow down your mowing speed if the mower does

not cut the leaves ﬁnely enough.

• Replace the blade when necessary with a Lawn-Boy

replacement blade.

Cutting Grass

• Cut only about a third of the grass blade at a time.

Do not cut below the 2 inch (51 mm) setting unless

the grass is sparse or it is late fall when grass growth

begins to slow down. Refer to Adjusting the Cutting

Height.

• When cutting grass over 6 inches (15 cm) tall, mow

at the highest cutting height setting and walk slower;

then mow again at a lower setting for the best lawn

appearance. If the grass is too long, the mower may

plug and cause the engine to stall.

• Mow only dry grass or leaves. Wet grass and leaves

tend to clump on the yard and can cause the mower

to plug or the engine to stall.

Wet grass or leaves can cause serious injury if

you slip and contact the blade. Mow only in dry

conditions.

• Alternate the mowing direction. This helps disperse

the clippings over the lawn for even fertilization.

• If the ﬁnished lawn appearance is unsatisfactory, try

one or more of the following:

– Replace the blade or have it sharpened.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.
