grass, which should not be left to grow too much between one cut and the next.
6. During hot and dry periods, the grass should be cut a little higher to prevent
the ground from drying out.
7. If the grass is very tall, it should be cut twice in a twenty-four hour period. The
first time with the blades at maximum
height, possibly reducing the cutting 2

width, and the second cut at the height
wanted.
8. The appearance of the lawn will
improve if you alternate the cutting in
both directions.
9. If the collector system tends to get
blocked with grass, you should reduce
the forward speed since this may be too
high for the condition of the grass. If the
problem persists, the probable causes are either badly sharpened blades or
deformed wings.
10. Be very careful when mowing near bushes or kerbs since these could distort
the horizontal position of the cutting deck, and damage its edge as well as the
blades.
