always stop engine when stopping tractor on grass areas.

pletely, as described above, before leavo
ing the operator's position; to empty
grass catcher, etc.

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