Once the material in the bale chamber has been
discharged the tailgate can be lifted to allow a portion of
rear half of the bale to be loaded into the chamber thus
allowing room for the material in the bale chamber to
rotate.
With a Tomahawk 1010 it will be found advantageous to
only allow half of the second bale to enter the chamber at
a time thus allowing room for each half to rotate.
Typically the rate of discharge may be controlled by bed
chain speed but only once rotation of the material within
the body of the machine has been achieved.
11.10 Discharging Round Bales
Gradually increase bed chain speed by means of the
speed control until discharge commences. Good
performance will only be achieved by getting the bale to
rotate within the chamber as shown in Figure 7.
Increasing the speed of the bed chain will increase the
rate of discharge until a maximum rate is achieved. If the
bed chain speed is too great, material will unroll from the
bale at a rate greater than can be discharged. This will be
indicated by a build up of material above the crossbeater
bale restraint.

11.11 Discharging Clamp Silage
Increase bed chain speed until the desired discharge rate
is achieved. Once the forward portion of the load has
been discharged, the tailgate can be lifted to ensure a
continuous feed rate.
11.12 General Discharging Instructions
If a large amount of loose material builds up above the
bale restraint it may be necessary to reverse the bed
chain until the loose material falls down behind the
crossbeater(s) before recommencing discharge.
When it is necessary to stop shredding part way through a
bale, always stop the bed chain rotation and put it in
reverse for a few seconds before stopping the rotor and
crossbeater(s). This allows the material in the area
around the crossbeater(s) and rotor to be blown clear of
the machine. Failure to do this may result in a blockage
when the machine is re-started.
The length of chop, evenness of feed and power
consumption will vary with the condition of the bale. In
general, baled silage and damp or caked straw materials
will require a higher power input than dry brittle materials.
Should the rotor or crossbeater(s) become blocked,
indicated by either slipping of the PTO clutch or failure of
the crossbeater(s) shear bolt, it may be necessary to turn
the rotor backwards. This may be achieved by levering
the rotor paddles with a post through the outlet chute.
Further access may be gained by removing the blockage
panels from the front of the upper and lower rotor
housing.
DUAL CHOP: Always fully raise the blade carrier
and lock it in position with pins before attempting to
remove blocked material from the crossbeater.
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.
Care must be taken when removing blocked material,
crossbeater blades are extremely sharp. Leather gloves
will give some protection against minor cuts.
12.0 MACHINE PROTECTION DEVICES
IMPORTANT:
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 13.7 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
IMPORTANT:
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.
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
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.
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.
