recommendations, in order to avoid any
unexpected accidents that may occur
whileoperatingthemachine.
Turn off the tractor and remove the key
from the ignition before performing any
maintenance, adjustment, lubrication,
cleaning jobs, etc. on the machine. Thus
you will avoid any accidental actuation
and avoid dangerous situations that may
causeseriousaccidents.
Do not open over remove covers and
safety shields on the machine while it is
operating.
Keep the hands away from gears and
other moving parts, as their movement
cancatchthemandcauseinjuries.
Lower the unloader nozzle to harvester
transfer. This way you will decrease the
height of the machine and avoid being
injured, for example by the electrical power
supply which can cause an accident from a
shockorevenelectrocution.
Do not get close to the machine before it
is completely motionless. Remember the
rotating parts do not stop moving
immediatelyafterturningoffthemachine.
Some parts move almost unnoticeably
andyoumaynotseethem.
It is prohibited to stay on the machine

The forage Harvesters and Choppers JF C-40, C-60 and C-120 can be driven by any tractor
equipped with double or independent clutch and with at least 40 hp at the PTO, it requires a
tractorofatleast50hp,fulllymeetingtheneedsoftheproducer.
They harvest corn, elephant grass, sugar cane, sorghum, sunflower, millet and any kind of
foragegrass.Theycanbeusedforensilage,asthedailyfoodtotheanimals.
The Harvesters and Choppers JF C-40, C-60 and C-120 are very versatile machines, that,
besides harvesting the already mentioned products, can also gather pre-dried grass and
green grass, just coupling the Platform JF 1300. They can also harvest corn and sorghum
planted with a reduced spacing, just coupling the Platform JF 500-4. The platforms are
optionalitems,soldseparately.
Note:
Do not start the machine suddenly, turn the PTO on with the tractor in low idle and
graduallyspeeditup.
Abruptly starting the machine can cause parts breaking and ejection by the outlet
chuteorotherdamagestothemachine.

Attention!
The washers that hold the outlet chute must
be attached with the rounded corner face
down (facing the outlet chute) and the
straight face upward (toward the nut), thus
avoidingfrictionof thewasher with theoutlet
chute,whichcanleadtothebreakingofit. Face rounded down!
