TO ADJUST MOWER CUTTING HEIGHT
(See Fig. 11)
The position of the attachment lift lever (A) determines the
cutting height.
A
Put attachment lift lever in desired cutting height slot.
The cutting height range is ap prox i mate ly 1" to 4". The
heights are measured from the ground to the blade tip with
the engine not running. These heights are approximate 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 de sired height.
TO ADJUST GAUGE WHEELS (See Fig. 12)
Gauge wheels are properly adjusted when they are slightly
off the ground when mower is at the desired cutting height
in operating position. Gauge wheels then keep the deck
in proper position to help prevent scalping in most terrain
conditions.
NOTE:Adjust gauge wheels with tractor on a flat level
surface.
Adjust mower to desired cutting height (See "TO AD -
JUST MOWER CUT TING HEIGHT" in the Operation
sec tion of this manual).
With mower in desired height of cut po si tion, gauge
wheels should be assembled so they are slightly off
the ground. In stall gauge wheel in appropriate hole as
shown and tighten se cure ly.
