OPERATION
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.
TO ADJUST MOWER CUTTING HEIGHT (See Figs. 18 and 19)
The position of the attachment lift indicator (W) determines the cutting height.

•Adjust mower to the desired cutting height by pressing the electric lift switch (A) in either the up or down direction.

Fig. 19
CAUTION: Continuing to press the electric lift switch after the mower deck has reached the minimum or maximum position may result in damage to the electric lift mechanism.The elec- tric lift mechanism is equipped with a thermal protection system. If the system overheats or fails to operate, allow the system to cool before attempting to operate again.
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 approximately
•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. 20)
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 this section of manual).
•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.
•Repeat for all, installing gauge wheel in same adjust- ment 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 hesitat- ing or cutting off when operating your equipment on rough, rolling terrain or hills.
•Select desired height of cut with attachment lift control.
•Start mower blades by engaging attachment 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 (See Fig. 21).

REVERSE OPERATION SYSTEM (ROS)
Your tractor is equipped with a Reverse Operation System (ROS). Any attempt by the operator to travel in the reverse direction with the attachment clutch engaged will shut off the engine unless ignition key is placed in the ROS "ON" position.
