TO ADJUST MOWER CUT TING HEIGHT

(See Fig. 8)

The po si tion of the at tach ment lift le ver (A) de ter mines the

cut ting height.

• Put attachment lift lever in desired cutting height slot.
The cutting height range is ap prox i mate ly 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 de sired height.

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 at tach ment clutch.

either the en tire grass catcher, on mowers

so equipped, or the deflector shield (S) in

place (See Fig. 11).

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.
NOTE:Adjust gauge wheels with tractor on a flat level surface.
• Adjust mower to desired cutting height (See “TO AD-

JUST MOWER CUT TING HEIGHT” in the Operation

sec tion of this manual).

•

With mower in desired height of cut po si tion, gauge wheels

should be assembled so they are slightly off the ground.

In stall gauge wheel in appropriate hole with shoulder

bolt, washer, washer, and lock nut and tighten se cure ly.

•

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.
USING THE REVERSE OPERATION SYSTEM (See Fig. 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) po si tion

to start movement.

• When use of the ROS is no longer needed, turn the

ignition key clockwise to engine "ON" position.
