OPERATION
The operation of any tractor can result in foreign objects thrown into the eyes, which
can result in severe eye damage. Always wear safety glasses or eye shields while op-
erating your tractor or performing any adjustments or repairs. We recommend a wide
vision safety mask over spectacles or standard safety glasses.

TO ADJUST MOWER CUTTING HEIGHT
(See Fig. 8)
The cutting height is controlled by turning the height ad-
justment knob in desired direction.
Turn knob clockwise (7_) to raise cutting height.
Turn knob counterclockwise (_)to lower cutting
height.
The cutting height range is approximately 1-1/2" to 4-1/2",
The heights are measured from the ground tothe blade tip
with the engine not running, These heights areapproximate
and may vary depending upon soil conditions, height of
grass and types of grass being mowed.
The average lawn should be cut to approximately 2-1/2
inches during the cool season and to over 3 inches
during hot months, For healthier and better looking
lawns, mow often and after moderate growth,
For best cutting performance, grass over 6 inches
in height should be mowed twice. Make the first cut
relatively high; the second to desired height.
