HOW TO USE THE MACHINE 29

4. The engine must run at full speed, both to ensure a sharp cut of the grass and to
get the necessary thrust to push the cuttings through the collector channel.
5. The frequency of mowing should be in relation to the rate of growth of the grass.
The grass 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. The best height of the grass on a
2
well-kept lawn is approx. 4-5 cm.
1
With one cut, 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 blades at maximum
height, possibly reducing the cutting
width, and the second cut at the
desired height.
8. The appearance of the lawn will improve if you alternate cutting in both directions.
9. If the engine speed is lowered while you are cutting grass or if the cutting deck
tends to get blocked, 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 as these could distort the hori-
zontal position of the cutting deck and damage its edge as well as the blades.
