1. Start tractor and release parking brake. 2. Slowly depress forward (K) or reverse (L) drive pedal to begin movement. Ground speed increases the further down the pedal is depressed. TO USE CRUISE CONTROL The cruise control feature can be used for forward travel only. SYSTEM CHARACTERISTICS The cruise control should only be used while mowing or transporting on relatively smooth, straight surfaces. Other conditions such as trimming at slow speeds may cause the cruise control to disengage. Do not use the cruise control on slopes, rough terrian or while trimmimg or turning. With forward drive pedal depressed to desired speed, pull cruise control lever (J) up and hold while lifting your foot off the pedal, then release the lever. To disengage the cruise control, depress the brake pedal or tap on forward drive pedal. 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 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 rela- tively 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 off the ground. Install gauge wheel in appropriate hole. Tighten securely. 3. Repeat for all, installing gauge wheel TO ADJUST MOWER CUTTING HEIGHT The position of the attachment lift lever (A) determines the cutting height. Put attachment lift lever in desired cut- ting 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. 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 at- tachment lift lever. 2. Start mower blades by engaging attachment clutch control. 15
