Make sure that the bale is not forced against the
Crossbeater as this may cause problems when
starting the machine. Before removing the strings, place
the two posts in the sockets on the Tailgate and put the
chain around the rear of the bale.
To load round bales reverse the machine forcing the
Tailgate under the bale. Lift the Tailgate slightly and
drive forward a short distance before raising it further
into a horizontal position. Cut the strings / netwrap on
the bale as low as possible and on the machine side of
the bale. Raise the Tailgate forcing the bale into the
Bale Chamber and before removing the strings /
netwrap completely. A second bale can be loaded and
carried on the Tailgate.
SHREDDING AND SPREADING MATERIAL
Adjust the Deflector to give the desired spread
direction.
Switch the control box on. Engage the spool valve on
the tractor, engage the PTO with the tractor engine on
idle, once the clutch has fully engaged increase the
speed rapidly. When the Rotor is rotating at working
speed start the Bed Chain by operating the forward
switch to begin the shredding and spreading of material.
It is important to ensure that the Rotor is turning at
full working speed before engaging the Bed Chain.
Failure to do so is likely to result in a blockage.
With two round bales in the machine, the Tailgate must
be lowered so that the second bale is not in contact with
the first. This allows the first bale to rotate freely within
the Bale Chamber, see Figure 2 for details.
Figure 2. Shredding round bales.
Do not force bales against the Crossbeater using
the tailgate as this will reduce the desired rotation
of the bale in the Bale Chamber. This may cause a
blockage and could also damage the machine.
When shredding rectangular bales, keep the tailgate in a
position so that the rear section of the bale is falling
away from the front section. Thus no pressure is
applied to the front half of the bale allowing it to rotate in
the Bale Chamber in the same way that a round bale
would rotate, see Figure 3.
Allow the front half of the bale to be almost fully
discharged before raising the Tailgate to shred the rear
half of the bale. Once the rear half of the bale is moving
on the Bed Chain, lower the Tailgate slightly to create
room for the bale to rotate within the Bale Chamber.
Figure 3. Shredding rectangular bales.
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
Crossbeater and Rotors. This allows the material in the
area around the Crossbeater 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 will vary with the condition of
the bale. Fresh clean straw will tend to result in a
longer chop length, where as old, slightly damp,
weathered or matted bales will tend to have a shorter
chop length. The power consumption will also vary with
the material being shredded. In general, baled silage
and damp or matted straw materials will require a
relatively high power input.
Should the Rotor or Crossbeater become blocked and
material become jammed it may be necessary to turn
the Rotor backwards. This can be achieved by pushing
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
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.
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 replacing. Grease must
be applied to the slipping surfaces via the grease nipple
before the Shear Bolt is replaced.
Shear Bolt Grades: Silage Machine - 10.9 M8 x 50
Dual Chop Machine - 8.8 M8 x 50
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
'Maintenance' 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.
