SAFETY RULES

TENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe

equipment can be wiped out by an operator’s single careless act.

In addition to the design and configuration of equipment, hazard control and accident prevention are dependent

upon the awareness, concern, judgment, and proper training of personnel involved in the operation, transport,

maintenance and storage of equipment.

It has been said “The best safety device is an informed, careful operator.” We ask you to be that kind of operator.

A-B Lock Nut, Washers, Bolt C- Adjustment hole

Each rotary cutter can be adjusted to several cutting

heights from 1.5 inches to 9 inches of cutting height by

moving the rockshaft control lever in conjunction with

moving the tailwheel adjustment bolt among the height

adjustment holes (see photo above)

1. Loosen bolt and lock nut (B), remove

bolt, washers and lock nut (A), raise

tailwheel to highest position and install bolt,

washer and lock nut (A).

2. Using rockshaft control lever, position front

of cutter at desired cutting height at location.

3. Adjust depth stop. (See your tractor Operator’s

Manual.)

IMPORTANT: Loosening the center link may allow

the driveline to contact the cutter frame or tractor

tires to contact the foot guards or chain shield. Raise

the cutter slowly and check for interference. Lengthen

tractor lift links to provide clearance to full height.

4. Adjust center link so rear of cutter is approxi-

mately 2 inches (51 mm) higher than front.

NOTE: Lift height may also be limited by installing

stops on rockshaft control lever bracket.

NOTE:

8. Lengthen tractor lift links, if necessary, to

provide clearance.

9. For cutter equipped with

iMatch Hitch, adjust tractor

center link until bushing is

centered in slot.

The rotary cutter should be operated at the highest

position which will give optimal cutting results. This

will help prevent the blades from striking the ground,

reducing blade wear and undue strain on the cutter.

For best results under heavier cutting conditions,

always tilt the rotary cutter approximately 2 inches

RNINGS M

ESULT IN

PERSONAL INJURY OR DEATH.

To help prevent severe injury or

death to you or someone else:

Never operate cutter when other people are in

the vicinity. Debris can be thrown hundreds of

feet. Keep all deflectors in place. Including those

on discharge opening at front and rear of deck.

Before starting machine, lower to the ground.

Engage tractor PTO and gradually increase

the speed.

6. Set tractor throttle for appropriate PTO

speed (540RPM).

Operate tractor at rated PTO speed. If engine

speed is too slow or too fast, machine may not

perform properly.

Where conditions make it necessary to slow

ground speed, shift to a lower gear rather than

reducing engine speed. The engine will maintain

rated speed and keep cutter running at

optimum cutting speed.

Operate machine from tractor seat only.

Never adjust machine while in motion.

Slow down when turning or traveling over

rough ground.

Avoid holes when operating on hillsides. Tractor

roll-over could result.

DANGER

ROTATING CUTTER BLADES.

STAND CLEAR UNTIL ALL MOTION HAS

STOPPED. TO

OID AN ACCIDENTAL

FALL FROM TRACTOR AND POSSIBLE

INJURY BY MOWER, IT IS RECOMMENDED

THAT TRACTOR BE EQUIPPED WITH

ROLLOVER PROTECTIVE SYSTEM (ROPS)

AND A SEAT BELT BE USED BY THE

OPERATOR FORALLMOWING OPERATIONS.

7. Place tractor in gear and proceed forward.

Note:

Tractor forward speed should be controlled by

gear selection, not engine speed. For maximum

cutting efficiency, forward speed should allow

cutter to maintain a constant, maximum blade

speed. If cutter stalls or tractor engine bogs,

disengage PTO. Before re-engaging PTO,

position cutter in a cut area and reduce tractor

throttle to idle. If rotary cutter continuously

stalls, select lower gear and/or increase

cutting height.

Shut off tractor engine and engage tractor

parking brake and/or place transmission in

“Park” when leaving tractor. Remove key

when leaving tractor unattended.

Components behind shields may rotate several

minutes after power is shut off. Look and listen

for evidence of rotation before removing shielding.

altitude so that rotary cutter rear &

front are with 1/2” of same height.

Material discharges from

cutter unevenly, or discharges

clumps of grass.

1. Grass or brush may be too high or thick.

Reduce ground speed but maintain

540 rpm at tractor PTO, or make

two passes over material. Raise rotary

cutter for the ﬁrst pass and lower for

the second pass, preferably cutting 90⁰

to the ﬁrst pass. Raise rear of rotary

cutter high enough to permit

material to discharge.

2. Grass wet.

Allow grass to dry before mowing.

Slow ground speed of tractor but

keep engine running at full PTO rpm.

Cutting lower will help.
