6. During hot and dry periods, the grass should
be cut a little higher to prevent the ground
from drying out.
7. The best height of the grass on a well-kept
lawn is approx. 4-5 cm. and with one mowing,
you do not need to remove more than a third
of the total height. If the grass is very tall,
it should be cut twice in a twenty-four hour
period. The first time with the cutting means
at maximum cutting height, possibly reducing
the cutting width and the second cut at the
height desired. Fig. 5.14)
8. The appearance of the lawn will improve if
you alternate the cutting in both directions
(Fig. 5.15)
9. If the collector system tends to get blocked
with grass, you should reduce the forward
speed as it may be too high for the condi
-
tion of the grass. If the problem persists, the
probable causes are either badly sharpened
cutting means or deformed fins.
10. Be very careful when mowing near bushes
or kerbs as these could distort the horizon
-
tal position of the cutting-means assembly
and damage its edge as well as the cutting
means.
