Regularly oil the PTO shaft spring plungers at both ends
of the shaft.

The frequencies stated are based on typical daily use for
bedding & feeding purposes. Continuous use for special
applications may necessitate more frequent lubrication.
ELECTRIC CONTROLS
Before maintaining any part of the electronic controls
and wires, disconnect the 12v supply. Failure to do so
may result in damage to the electronic circuit
controlling the bed chain speed.
It is recommended that the controls are repaired by a
competent person. Please contact Teagle Machinery
when repairs are required. Copies of the circuit
diagram are available from the manufacturer on
request.
When the machine is not being used it is
recommended that the Control Box is stored safely
away from the machine in a dry position. The plug on
the end of the machine cable should be kept stored in
the bracket provided to keep it clean and safe from
damage.
ELECTRIC CONTROLS - BED SPEED ADJUSTMENT
Each tractor has different flow rates from it’s hydraulic
system. The control desk is programmable to optimise
the performance of the machine depending on the oil
flow that the tractor can deliver.
The following instructions will allow you to programme
the stop position and high speed position of the bed
speed dial. This process will allow maximum bed
speed, and control without compromising the other
services the valve block can provide.
To perform this operation the following steps must be
followed exactly.
1. Turn on the tractor and engage the hydraulic
systems.
2. Set the tractor engine to normal working speed.
3. Turn Off the control box.
4. Turn the bed speed dial down to 0.5.
5. The following buttons must be pressed & held
down in this order;
I) Bed Chain Forward.
II) Giraffe Chute/Raise Knives/Long Chop.
III) Power On.
6. Hold the sequence of buttons for 8 seconds until
both the bed forward, and on LED’s illuminate.
Release buttons and the LED’s should flash
alternately.
7. Using the Giraffe Chute/Raise Knives/Long
Chop to slow down, and the Lower Knives/Short
Chop to speed up. Slow the bed down to the
point where it just stops.
8. Press the Off button to save the slow speed.
You have now programed the control desk for it’s
minimum bed speed. To programme the control desk
for its maximum speed repeat the same process
again, BUT Step 4 should have the speed dial set to
10 and in Step 7 you should increase the bed speed to
almost it’s maximum speed.
OPTIONAL EXTRAS
OVERSIZE WHEELS
Larger wheels may be fitted to the Tomahawk.
DRAWBAR JACK
Where the machine is fitted with a Drawbar Jack,
adjust the height of the Drawbar to match the height of
the hitch point on the tractor. Reverse the tractor and
attach the drawbar. Lower the machine until the weight
is fully transferred to the tractor. Remove the pin
retaining the Jack to the Drawbar and transfer it onto
the transport position across the front of the Chassis.
DISPOSAL
At the end of the machine’s working life, the method of
disposal must be within the legislation laid down by the
local authority or the National Environment Agency.
The machine is composed of ferrous materials,
synthetic paints and rubber compounds.
