OPERATION

TO ADJUST MOWER CUTTING HEIGHT (See Fig. 8)

The position of the attachment lift lever (A) determines the cutting height.

A

Fig. 8

•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 approximately 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 (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 prop- er position to help prevent scalping in most terrain conditions.

•Adjust mower to desired cutting height (See “TO AD- JUST MOWER CUTTING HEIGHT” in the Operation section of this manual).

•Withmowerindesiredheightofcutposition,gaugewheels should be assembled so they are slightly off the ground. Install gauge wheel in appropriate hole with shoulder bolt, washer, washer, and locknut and tighten securely.

•Repeat for opposite side installing gauge wheel in same adjustment hole.

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.

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

USINGTHEREVERSEOPERATIONSYSTEM(SeeFig.10) Only use if you are certain no children or other bystanders will enter the mowing area.

•Move motion control lever to neutral position.

•With engine running, turn ignition key counterclockwise to ROS "ON" position.

•Look down and behind before and while backing.

•Slowly move motion control lever to reverse (R) position to start movement.

•When use of the ROS is no longer needed, turn the ignition key clockwise to engine "ON" position.

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 lever.

•Start mower blades by engaging attachment clutch.

TO STOP MOWER BLADES -

•Disengage attachment clutch control.

CAUTION: Donot operatethe mowerwithout either the entire grass catcher, on mowers so equipped, or the deflector shield (S) in place (See Fig. 11).
