/ CUTTING MEANS
9.2.1 Aligning the cutting means assembly
The cutting means assembly should be correctly
adjusted to obtain an evenly mown lawn (fig. ).
If mowing is uneven, check the
tyre pressure (par. 7.1.3).
If this is not sufficient to achieve an even
cut, please contact your Dealer to adjust the
alignment of the cutting means assembly.
9.2.2 Cutting means
Badly sharpened cutting means pull at the
grass and cause the lawn to turn yellow.
SAFETY INSTRUCTION
Always replace damaged, bent or worn pairs
of cutting means, together with their nuts and
bolts, in order to maintain their balance.
