The cutting height range is approximately 1-1/2" to 4-1/2". The heights are mea- sured 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

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: Be sure tractor is on a flat level surface.

1.Lower mower and adjust mower to de- sired cutting height(See "TO ADJUST MOWER CUTTING HEIGHT" in this

section of manual).

2.Remove retainer spring and clevis pin which secure each gauge wheel bar.

3.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.

4.Replace retainer spring into clevis pin.

5.Be sure all gauge wheels are in the same setting.

IMPORTANT: Be sure to readjust gauge wheels if you change the cutting height of the mower deck.

REVERSE OPERATION SYSTEM (ROS)

Your tractor is equipped with a Reverse

Operation System (ROS). Any attempt by the operator to travel in the reverse direc- tion with the attachment clutch engaged will shut off the engine unless ignition key is placed in the ROS "ON" position.

_WARNING: Backing up with the at- tachment clutch engaged while mowing is strongly discouraged. Turning the ROS "ON", to allow reverse operation with the attachment clutch engaged, should only be clone when the operator decides it is necessary to reposition the machine with the attachment engaged. Do not mow in reverse unless absolutely necessary.

USING THE REVERSE OPERATION SYSTEM -

1.Depress clutch/brake pedal all the way down and hold.

2.With engine running, turn ignition key

counterclockwise to ROS "ON" posi- tion.
