OPERATION TO ADJUST MOWER CUTTING HEIGHT (See Fig. 8) The cutting height is controlled by turning the height adjustment knob in desired direction. • Turn knob clockwise ( ) to raise cutting height. • Turn knob counterclockwise ( ) to lower cutting height. The cutting height range is approximately 1-1/2" 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 desired height. TO ADJUST GAUGE WHEELS (See Fig. 9) 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 CUTTING HEIGHT" in the Operation section of this manual). • Remove retainer spring and clevis pin which secure each gauge wheel bar. • Lower gauge wheels to ground. Raise gauge wheels slightly to align holes in bracket and gauge wheel bar and insert clevis pin. Gauge wheels should be slightly off the ground. • Replace retainer spring into clevis pin. • Be sure all gauge wheels are in the same setting.
