Mowing
NOTE: Avoid mowing when the grass is wet from rain or dew. Wet grass may
form clumps which interfere with the mulching action and reduce runtime.
The best time to mow grass is late afternoon when the grass is dry and the
newly cut area will not be exposed to direct sunlight.

General tips
1.
Make sure that the lawn is clear of stones, sticks, wires or other objects that could
damage the product or its engine.
2.
Do not cut wet grass because it tends to stick to the underbody of the product,
preventing the proper discharge of grass clippings, and it could also cause you
to slip and fall.
3.
Never cut off more than one-third of the total length
of the grass for a healthy lawn. In the autumn, lawns
should only be cut as long as there is growth.
4. Slowly push the product forward.
5.
Mow in slightly overlapping rows. The most effective
pattern for mowing lawns is straight lines along one of
the sides. This keeps the rows even and ensures that
all the lawn is cut without missing any spots (Fig. 26).
