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 hesitating or
cutting off when operating your equipment
on rough, rolling terrain or hills.
1. Select desired height of cut with attach-
ment lift lever.
2. Start mower blades by engaging attach-
ment clutch control.
TO STOP MOWER BLADES
Disengage attachment clutch con trol.
CAUTION: Do not operate the mower
without either the en tire grass catcher, on
mowers so equipped, or the deflector shield
(S) in place.
TO ADJUST GAUGE WHEELS
Gauge wheels are prop er ly ad just ed when
they are slight ly 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.
1. Adjust mower to desired cutting height
(See “TO AD JUST MOWER CUT TING
HEIGHT” in this sec tion of manual).
2. 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 ap pro pri ate hole. Tighten
se cure ly.
3. Repeat for all, installing gauge wheel in
same adjustment hole.
TO ADJUST MOWER CUT TING HEIGHT
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 condi-
tions, height of grass and types of grass
being mowed.
• The average lawn should be cut to ap-
proximately 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 MOVE FORWARD AND
BACKWARD
The direction and speed of movement is
controlled by the motion control lever. (J)
1. Start tractor with motion control le ver in
neutral position.
2. Release parking brake.
3. Slowly move motion control lever to
desired position.
