handle moved towards the position marked by the hare to
give a 1:1 ratio between PTO and discharge rotor speeds.
For shredding silage and other wet materials it is
recommended that low rotor speed be used since long
throw distances are not usually required. To select low
rotor speed, the gearbox handle should be moved to the
position marked by the tortoise to give a 1.85:1 ratio. The
machine may be used at reduced PTO speeds and still
deliver material to the desired position. Low PTO speeds
should be used with caution as a blockage in the rotor
housing may result. Do not operate with a PTO speed less
than 300 rpm.
11.2 Right Hand Chute
Adjust the position of the chute to deliver material to the
desired location, typically this will be down beside the
machine for feeding and elevated for bedding.
11.3 Sloping Swivel Chute
The swivel chute rotates through 280 degrees and can be
operated to either side of, and behind the machine.
To deliver silage close to the machine, position the chute
so that material is delivered onto the feed passage slide.
The position of the slide can be adjusted to deliver the
material accurately. Alternatively the position of the
material can be controlled by the chute, it may be
necessary to rotate the chute fully delivering material
alongside the drawbar.
The discharge of baled silage along the left hand
side of the machine is not recommended.
In transport, rotate the chute to the right hand side of the
machine aligning the indicators on the chute and top
housing. Fully lower the deflector to keep the width and
height of the machine to a minimum.
11.4 Twin Chute
The twin chute machine can discharge through either the
standard right hand chute or the swivel giraffe chute,
depending on operating requirements.
To select the desired chute move the chute selection
segment via the buttons on the control desk.
11.5 Dual Chop Operation
Dual Chop machines cannot chop silage or materials
with a high moisture content.
The sliding blade carrier is controlled through the hydraulic
spool valve. An indicator attached to the blade beam
shows the engaged / disengaged positions of the sliding
blade carrier.
When a long chop length is desired, raise the blade carrier
thus disengaging the blades.
When a fine chop length is desired, lower the blade carrier
fully
to engage the blades against the crossbeater and put
the gearbox in low discharge speed. Before lowering the
blade carrier, stop the bed chain and wait for the material
to stop flowing into the rotor.
Do not use intermediate positions as damage may occur.
11.6 Starting The Machine
Switch the control desk on. Engage the hydraulic spool
valve on the tractor making sure the bed chain has not
been started.
Position the selected chute and deflector to give the
desired spread direction.
Engage the PTO with the tractor engine at idle speed and
increase the speed rapidly to working speed (540rpm)
when the tractor clutch has engaged fully.
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.
11.7 Before Commencing Discharge
If the machine is loaded to capacity with bales, the tailgate
must remain horizontal until the material in the body has
been discharged. This is necessary to allow material within
the body of the machine to rotate freely once it comes into
contact with the crossbeater(s). No attempt should ever
be made to force material towards the crossbeater(s) using
the tailgate.
With the bed chain speed dial on the control desk set to
zero, switch the bed chain on in the forward direction by
pressing the bed chain forward button once. General
discharging instructions follow after the specific round/
square bale and clamp silage instructions below.
11.9 Discharging Square Bales
Gradually increase bed chain speed by means of the
speed control until shredding commences. It is then
advisable to increase bed chain speed to a point at which
the slices of the bale being shredded are forced up and
over the material coming forward. This rotational motion is
represented in Figure 6.
Figure 6. Rotation of square bales
Where a bale lift is fitted to a Tomahawk 1010, release the
portion of the bale retained by the bale lift only when the
first portion has been discharged which is usually indicated
by a large fall in discharge rate.
