Teagle Tomahawk 7100, Operator'S Manual

Page: 24 / 40

DANGER: Never begin to unblock a machine until
the PTO has been disengaged, the engine stopped
with the key removed from the ignition, and the machine
has come to rest.
CAUTION: Care must be taken when removing
blocked material, crossbeater blades are extremely
sharp. Leather gloves will give some protection against
minor cuts.
11.11 Monitoring the tractor and machine during
chopping.
During the process of chopping straw and other materials
a significant volume of dust is produced as part of the
process.
Depending on the situation that the machine is working in
the tractor will be exposed to the dust generated by the
machine, if working outside the wind may drive the dust
towards the tractor. Where the tractor is stationary whilst
the machine is being used to chop material for an
extended period this dust will result in the clogging of air
intake filters for the engine and cooling radiators.
IMPORTANT. It will be necessary to monitor
carefully the operating temperature of the tractor,
stopping regularly to clean air filters and radiators in
accordance with the operator’s manual for the tractor.
Where the operator also loads the machine using another
vehicle it is advisable to fit a warning device that will
indicate to the operator remotely when the tractor oil and
water systems are getting too hot.
WARNING. Failure to monitor and maintain the
tractor during chopping may result in it overheating
and causing a significant fire which could result in the
destruction of the tractor, Tomahawk and surrounding
buildings.
WARNING. Do not attempt to fight a fire unless you
have received training. If unsure evacuate the area,
alert others working in the vicinity of the machine and call
the fire fighting service.
11.12 Fire risk during chopping process
During chopping there are likely to be foreign objects in
the bales, in chopping this material there is a risk that a
spark could ignite the straw being chopped. Burning or
smouldering straw could then result in a fire in the
material already chopped.
WARNING. Do not attempt to fight a fire unless you
have received training. If unsure evacuate the area,
alert others working in the vicinity of the machine and call
the fire fighting service.
12.0 MACHINE PROTECTION DEVICES
NOTE: The machine is fitted with a shear bolt on the
crossbeater drive line. After a blockage, the shear bolt
may have failed and require replacement. See paragraph
13.6 in the maintenance section.
Shear bolt grades:
Silage / straw machine 10.9 M8 x 50 mm
Dual Chop machine 8.8 M8 x 50 mm
NOTE: The machine is fitted with a slip clutch on the rotor
shaft. If this slips repeatedly, the machine must be fully
examined to check that there is no fault or blockage
before tightening the slip clutch. Refer to PTO shaft parts
list for the correct slip clutch setting.
CAUTION: The slip clutch can get very hot. Care
should be taken when removing it from either the
machine or tractor.
13.0 MAINTENANCE
13.1 Safety
DANGER: Never enter the bale chamber unless the
PTO has been disengaged, the engine has been
stopped, the key removed and the machine come to rest.
CAUTION: Always keep your hands away from the
edges of blades
-
particularly new ones, as they are
extremely sharp. Be aware that even when the leading
edges of the blades appear to be blunt the trailing edges
will remain sharp. Leather gloves will provide some
protection against minor cuts.
13.2 Blades
When carrying out maintenance work on the blades enter
the bale chamber via the tailgate. Wedge the rotor and
crossbeater(s) to prevent them from turning reducing the
risk of trapping hands between the knives and bale
restraint fingers.
CAUTION: Extreme care must be taken when
carrying out maintenance work on or around the
blades as they are incredibly sharp. When replacing
blades use 13mm ring spanners with long handles to
allow the bolts to be removed whilst avoiding contact with
the sharp edges of the blades. Always wear leather
gloves, and work slowly and methodically.
13.2.1 Silage Crossbeater Blades
Cover areas of the crossbeater(s) not being worked on
with old carpet or hessian sacking.
Blades can simply be rotated and repositioned to achieve
a new sharp cutting edge. When both edges are blunt the
blades will require replacement.
To achieve greater cutting aggression, a selection of
blades can be positioned using the outer holes on the
crossbeater(s) rings.
13.2.2 Dual Chop Blades
Disengage the blades by raising the blade carrier. Enter
the bale chamber and lock the blade carrier in the raised
position by placing two bars through the 19mm (¾”)
diameter holes in the slides.
Loosen the M12 bolt (1) from the cover plate located on
the left hand mid body panel, as indicated in Figure 8.
Rotate the cover plate and position as shown in Figure 9.
