Mulching Tips
Mulching finely cuts the grass so that the grass can be easily
recycled. Because the nutrients are returned to the soil, the
lawn will need less fertilizer. To correctly mulch the lawn,
follow the tips below.
• The grass must be dry. If the grass is wet, it will be
difficult to cut and cause heavy clumps of grass.
• The grass must not be too tall. The maximum height to
effectively cut is 4 1/2 inches. Set the height adjusters
so that only the top third of the grass is cut.
• If the grass is more than 4 1/2 inches high, two

mowings will be necessary. For the first mowing, set the
height adjusters in the highest position. Then, lower the
height adjusters for the second mowing.
• Keep a sharp edge on the blade. A blade that is not
sharp will cause the ends of the grass to become brown.
• Clean the underside of the mower housing. Grass and
other debris can keep the mower from working
correctly.
If the quality of cut is marginal, try the following:
• Set the height adjusters at a higher cutting height.
• Cut the grass more frequently.
• Operate the mower at a slower ground speed.
• Overlap the cutting swaths instead of cutting a full
swath with each pass.
• Mow across the marginal areas a second time.
WARNING: To prevent the engine from
starting, disconnect the wire from the
spark plug.
1. Ensure the grass bag is removed.
2. Lift the mulching cover.
3. Slide the two tabs (A, Figure 11) on the side deflector
under the pivot pin.
4. Lower the side deflector. Make sure the locking tabs (B)
go through the slots in the side deflector.
5. Release the mulching cover (it will lay on top of the side
discharge deflector).
