Hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper

training involved in the operation, transport, storage and maintenance of the Rotary Cutter. Therefore, it is

absolutely essential that no one operates the Rotary Cutter without first having read, fully understood and

SAFETYINFORMATION

DANGER

TOPREVENTINJURIES:

Do not operate a broken or bent driveline. Such

drivelines can break apart while rotating at high

speeds causing serious injury or death. Always

remove Rotary Cutter from service until damaged

drivelinesarerepairedorreplaced.

DANGER

TOPREVENTINJURIES:

Always disconnect main driveline from tractor PTO

before servicing underside of cutter. PTO can be

engaged if tractor is started causing damage to

cutter,seriousinjuryordeath

DANGER

TOPREVENTINJURIES:

Tractor PTO shield, gearbox shaft shield, and

driveline shields must be secured in place when

operating cutter to avoid injury or death from

entanglementindriveline.

DANGER

TOPREVENTINJURIES:

Allguardsandshieldsmustbeinstalledandingood

workingconditionatalltimesduringcutteroperation.

DANGER

TOPREVENTINJURIES:

Do not engage tractor PTO while hooking-up and

unhooking driveline or while someone is standing

near the driveline. A person’s body and/or clothing

can become entangled in the driveline resulting in

seriousinjuryordeath.

DANGER

TOPREVENTINJURIES:

Keep others away while cutter is operating. It can

discharge objects at high speeds. Therefor, the use

of front and rear safety guards is strongly

recommended when cutting along highways and in

areas where people may be present. Stop blade

rotationifabystanderiswithinatleast300feet.

DANGER

TOPREVENTINJURIES:

Neverplacehandsorfeetunderthedeckorattempt

tomakeadjustmentstothecutterwithPTOengaged.

Cutterbladesrotatingathighspeedscannotbeseen

and are located close to the deck housing. Body

extremitiescanbecutoffinstantly.

DANGER

TOPREVENTINJURIES:

Do not operate and/or travel across steep inclines

whereatractorcanrolloverresultinginseriousinjury

ordeath.

Consult yourtractor’s manual for acceptable inclines

thetractoriscapableoftravelingacross.

DANGER

TOPREVENTINJURIES:

Do not use cutter as a fan. Cutting blades are not
