TO OPERATE MOWER (See Fig. 8)
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.
• Select desired height of cut.
• Lower mower with attachment lift control.
• Start mower blades by engaging attachment clutch
control.
• TO STOP MOWER BLADES - disengage attachment
clutch con trol.
TO ADJUST GAUGE WHEELS (See Fig. 7)
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.

TO ADJUST MOWER CUTTING HEIGHT
(See Fig. 6)
The cutting height is controlled by turning the height ad-
just ment knob in desired direction.
• Turn knob clockwise (
) to raise cutting height.
• Turn knob counterclockwise ( ) to lower cutting
height.
The cutting height range is ap prox i mate ly 1-1/2" to 4". The
heights are measured from the ground to the blade tip with
the engine not running. These heights are ap proxi mate
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 USE THROTTLE CONTROL (See Fig. 5)
Always operate engine at full speed (fast).
•
Operating engine at less than full speed (fast) reduces
engine's operating efficiency.
• Full speed (fast) of fers the best mower per for mance.
TO MOVE FORWARD AND BACKWARD
The direction and speed of movement is controlled by the
forward and reverse drive pedals.
• Start tractor and release parking brake.
•
Slowly depress forward or reverse 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 terrain or while trimming or turning.
•
With forward drive pedal depressed to desired speed,
move cruise control lever forward to “SET” position and
hold while lifting your foot off the pedal, then release
the cruise control lever.
• To disengage the cruise control, pull the lever backward
to “OFF” position, or fully depress the brake pedal.
NOTE: Be sure tractor is on a flat level surface.
• Lower mower and adjust mower to desired cutting
height(See “TO AD JUST MOWER CUT TING HEIGHT”
in this sec tion of manual).
• Remove retainer spring and clevis pin which secure
each gauge wheel bar.
• 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.
• Replace retainer spring into clevis pin.
• 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.
