TO ADJUST MOWER CUTTING HEIGHT The position of the attachment lift lever (A) determines the cutting height. • Put attachment lift lever in desired cutting height slot. The cutting height range is approximately 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 ap- proximately 2-1/2" during the cool season and to over 3" during hot months. For healthier and better looking lawns, mow often and after moderate growth. • For best cutting performance, grass over 6" in height should be mowed twice. Make the first cut relatively high; the second to desired height. TO ADJUST GAUGE WHEELS 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. 1. Adjust mower to desired cutting height (See "TO ADJUST MOWER CUTTING HEIGHT" in this section of manual). 2. With mower in desired height of cut position, gauge wheels should be assembled so they are slightly offthe ground. Install gauge wheel in appropriate hole. Tighten securely. 3. Repeat for all, installing gauge wheel in same adjustment hole. TO OPERATE MOWER Your tractor is equipped with an operator presence sensing switch. Any attempt by the operator to leave the seat with the engine running and the attachment clutch engaged will shut off the engine. You must remain fully and centrally positioned in the seat to prevent the engine from hesitating or cutting off when operating your equipment on rough, rolling terrain or hills. 1. Select desired height of cut with attach- ment lift lever. 2. Start mower blades by engaging attach- ment clutch control. TO STOP MOWER BLADES Disengage attachment clutch control. _CAUTION: Do not operate the mower without either the entire grass catcher, on mowers so equipped, or the deflector shield (S) in place. I -- ...... }7 TO OPERATE ON HILLS ,_WARNING" Do not drive up or down hills with slopes greater than 15 ° and do not drive across any slope. Use the slope guide provided at the back of this manual. • Choosethe slowest speed before starting up or down hills. • Avoid stopping or changing speed on hills. • If stopping is absolutely necessary, push clutch/brake pedal quicklyto brake position and engage parking brake. • Move motion control lever to neutral position. IMPORTANT: The motion control lever does not return to neutral position when the clutch/ brake pedal is depressed. • To restart movement, slowly release park- ing brake and clutch/brake pedal. • Slowly move motion control lever to slow- est setting. • Make all turns sJowly. 14
