Some models have an optional mulcher plug. If the mulcher plug is installed, the grass is finely cut and will easily recycle. Because the nutrients are returned to the soil, the lawn will need less fertilizer.

The following tips will increase performance and improve the appearance of the lawn.

S The grass must be dry. If the grass is wet, it will be difficult to cut and cause heavy clumps of grass. S The grass must not be too tall. The maximum height to effectively cut is 9.8 cm. Set the height adjusters so that only the top third of the grass is cut. S If the grass is more than 9.8 cm 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. S Keep a sharp edge on the blade. A blade that is not sharp will cause the ends of the grass to become brown. S Clean the bottom of the mower housing. If grass and other debris accumulate on the bottom of the mower housing, performance will be reduced. To improve the quality of cut, try the following: S raise height of cut S cut more frequently S operate at a slower ground speed S reduce width of cut S change direction S mow a second time
