should not be left to grow too much between
one cut and the next.
6. D uring hot and dry periods, the grass should
be cut a little higher to prevent the ground
from drying out.
7. T he 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. 5.15)
8. T he appearance of the lawn will improve if
you alternate the cutting in both directions.
Fig. 5.16)
9. I f 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. B e 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.
