Only qualified people should ope ate this machine.
Ope ato should wea ha d hat, safety glasses and
safety shoes. It is ecommended that t acto be
equipped with Rollove P otective System (ROPS)
and a seat belt be used. Befo e beginning ope a-
tion, clea wo k a ea of objects that may be picked
up and th own. Check fo ditches, stumps, holes o
othe obstacles that could upset t acto o damage
cutte . Always tu n off t acto engine, set pa king
b ake, and allow cutte blades to come to a complete
stop befo e dismounting t acto .
3-2 TRANSPORTIN
When implement is t anspo ted on oad o highway,
day o night, use t acto flashing wa ning lights
unless p ohibited by law. A slow moving vehicle
(SMV) sign must be visible f om the ea by
app oaching vehicles. A b acket fo SMV sign is

B. Make ce tain jackstand is sto ed fo wo k.
C. Sta t t acto . Raise cutte and emove stop
colla s. Remove wing t anspo t lock pins and place
in sto age hole (Figu e 2-4). Lowe wings to wo king
position. Raise/lowe cutte to wo king height. The
cutte should be ope ated at the highest position that
will give desi ed cutting esults. This will help p e-
vent the blades f om st iking the g ound, educing
blade wea and undue st ain on the whole machine.
Continuous g ound and blade contact could fo ce
blades into deck a ea.
D. Install stop colla s on axle cylinde at desi ed
cutting height. Sto e emaining stop colla s (if any)
a ound self-leveling linkage od.
E. With t acto at idle speed, engage PTO d ive.
IMPORTANT
DURING OPERATION THE HYDRAULIC VALVE
WING LEVERS MUST BE LOCKED IN THE FLOAT
POSITION TO AVOID DAMAGE TO THE CYLIN-
DERS AND AXLES.
IT IS HAZARDOUS TO OPERATE UNIT
WITH WIN S RAISED ABOVE ROUND.
DAMA E CAN OCCUR TO WIN DRIVE-
LINE IF WIN S ARE OPERATED ABOVE 60°.
KEEP CLEAR OF MACHINE WHEN
RAISIN OR LOWERIN WIN S. DO
NOT “DRIVE-OUT” TRANSPORT LOCK
PIN IF IT IS TI HT A AINST WIN LU .
TO REMOVE PIN, RETRACT WIN LIFT
CYLINDER TO RELIEVE LOAD ON PIN.

FAILURE TO MATCH VALVE TO TRAC-
TOR HYDRAULIC SYSTEM BY USIN
INCORRECT PLU WILL CAUSE DAM-
A E TO TRACTOR.
2-3 PITCH ADJUSTMENT
The pitch of the cutte (f ont to ea ) is cont olled by
adjusting the linkage ods (Figu e 2-3). Sho tening
the linkage od assemblies will aise the f ont of the
cutte . Lengthening the linkage od assemblies will
lowe the f ont of the cutte . The pitch adjustment is
p ima ily fo compensating fo the diffe ent height of
t acto d awba . As desc ibed in the following, it can
also be used to alte the cutting pe fo mance. Note
that ope ating the cutte at any pitch othe than pa -
allel to the g ound will p oduce a slightly uneven cut.
Additional mulching of cut mate ial may be attained
by ope ating with the ea of the cutte slightly lowe
than the f ont. This will keep the foliage unde neath
cutte longe , esulting in smalle pieces of cut mate-
ial. This will inc ease the cutte ho sepowe equi e-
ments.
If you a e cutting in dense mate ial, ope ating cutte
with the ea slightly highe than the f ont will allow
an inc eased volume of cut mate ial to exit f om
unde neath cutte . This will dec ease the cutte
ho sepowe equi ements.
OPERATIN CUTTER WITH REAR
LOWERED EXCESSIVELY WILL RESULT
IN AN UNEVEN CUT AND COULD CAUSE
RAPID BLADE, SKID AND DRIVELINE
WEAR AND POSSIBLY CAUSE STRUC-
TURAL FAILURES IN THE WIN HIN E
AREA.
Adjust the pitch as follows:
TO AVOID SERIOUS INJURY OR DEATH:
DO NOT PLACE HANDS, FEET OR
OTHER PARTS OF THE BODY UNDER
CUTTER WHILE MAKIN ADJUST-
MENTS. NEVER MAKE ADJUSTMENTS
WITH CUTTER OPERATIN .
CAUTION

Figu e 2-3 Linkage Rods
IMPORTANT
NEVER ADJUST THE LEVELIN ROD SO THAT
THE THREADED END OF ANY ROD IS NOT
FULLY EN A ED IN THE TURNBUCKLE.
A. Loosen jam nut on each linkage od assem-
bly (Figu e 2-3).
B. Rotate the od to lengthen o sho ten the lev-
eling od assemblies. Sho tening the ods will aise
the f ont of the cutte and lengthening ods will lowe
the f ont of the cutte . While adjusting, alte nate
f om one od to the othe .
C. When the desired pitch is attained, make a
final adjustment of the rods so that each will be
under the same amount of tension. This may be
done by tapping the rods and “tuning” them to
the same sound.
D. Re-tighten jam nut.
NOTE
If the cutte is allowed to est on the g ound in o de
to elieve tension on the ods, the tongue must be
disconnected f om the t acto to allow it to move.
2-4 WIN ADJUSTMENT
Wings should be adjusted befo e use if they a e not
level (pa allel) left to ight with cente deck section.
Adjust as follows:
A. Lowe cutte until skids on cente section a e
app oximately 1-2 inches (25-51mm) off g ound.
B. Remove wing t anspo t lock pin(s) and place
in pin sto age hole. (Figu e 2-4)
WARNIN
STAND CLEAR OF WIN (S) DURIN
AND AFTER REMOVAL OF TRANSPORT
LOCK PIN(S). AIR IN HYDRAULIC COM-
PONENTS MAY ALLOW WIN (S) TO

When implement is t anspo ted on oad o highway,
day o night, use t acto flashing wa ning lights
unless p ohibited by law. A slow moving vehicle
(SMV) sign must be visible f om the ea by
app oaching vehicles. A b acket fo SMV sign is
p ovided on the cente section shield. Do not
exceed 15 mph (24 kph) when traveling. P epa e
machine fo t anspo ting as follows:
A. Disengage tractor PTO.
B. Raise cutter and install stop collars on
height adjustment cylinder. (Figure 2-3)
C. Rotate cylinder stops away from wing cylin-
ders, raise wing(s) and insert transport lock pin(s).

B. Make ce tain jackstand is sto ed fo wo k.
C. Sta t t acto . Raise cutte and emove stop
colla s. Remove wing t anspo t lock pins and place
in sto age hole (Figu e 2-4). Lowe wings to wo king
position. Raise/lowe cutte to wo king height. The
cutte should be ope ated at the highest position that
will give desi ed cutting esults. This will help p e-
vent the blades f om st iking the g ound, educing
blade wea and undue st ain on the whole machine.
Continuous g ound and blade contact could fo ce
blades into deck a ea.
D. Install stop colla s on axle cylinde at desi ed
cutting height. Sto e emaining stop colla s (if any)
a ound self-leveling linkage od.
E. With t acto at idle speed, engage PTO d ive.

F. Place t acto in gea and p oceed fo wa d.
Advance t acto th ottle to co ect PTO speed fo
implement (540 RPM). T acto fo wa d speed
should be cont olled by gea selection, not engine
speed. For maximum cutting efficiency, forward
speed should allow cutter to maintain a con-
stant, maximum blade speed. Failu e to maintain
p ope blade RPM will esult in poo cutting pe fo -
mance and excessive blade and blade bolt wea . If
PTO d ive is disengaged due to cutte stalling o
t acto engine bogging, cutte must be aised to
maximum cutting height and t acto th ottle educed
to idle befo e e-engaging. When in a eas with tall,
dense mate ial, the f ont skids may push mate ial
ove and hold it down long enough to p event blades
f om cutting it. This will be evidenced by st eaking in
the skid a ea. To alleviate this p oblem, emove the
f ont skids.
IMPORTANT
DURING OPERATION, STOP AT REGULAR
INTERVALS AND CLEAN ACCUMULATED
DEBRIS FROM THE TOP OF CUTTER DECK,
ESPECIALLY AROUND DRIVELINES AND GEAR-
BOXES. THIS WILL HELP PREVENT MATERIAL
