cut twice in a twenty-four hour period.
The first time with the blades at maxi-

improve if you alternate the 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 since these could distort
the horizontal position of the cutting deck, and damage its edge as well as the
blades.
