SAFETY FIRST!
1. READ THE INSTRUCTION BOOK THOROUGHLY
before attempting to operate or carry out any
maintenance on the machine. If you do not
understand any part of this manual, ask your dealer
for assistance.
2. ALWAYS CARRY OUT SAFE
MAINTENANCE. Never clean, adjust or maintain
the machine until the engine has been stopped, the
machine come to rest, the PTO disengaged and the
key removed.
3. NEVER WORK UNDER A MACHINE RAISED
ON THE 3-POINT LINKAGE unless it is securely
supported.
4. NEVER OPERATE THE MACHINE WITH ANY
PARTS OR GUARDS MISSING. Check that all
guards including the PTO shaft guards are in good
condition and in place before operating the machine.
5OPERATE SAFELY. Before starting work, check
that there are no persons or animals in the
immediate vicinity of the machine or tractor. Always
maintain full control of the tractor and machine.
Ensure that you know how to stop the tractor and
machine quickly in case of emergency.
6. SECURE THE PTO GUARD BY MEANS OF
CHECK CHAINS to suitable points on the tractor
and machine to prevent the outer plastic shield from
rotating.
7. NEVER STAND BETWEEN THE MACHINE AND
THE TRACTOR WHEELS.
8. DO NOT WEAR LOOSE OR RAGGED CLOTHING
9. BEWARE OF DUST. Under dusty conditions, keep
the cab windows and doors closed. The use of a
dust mask conforming to EN149 is strongly
recommended.
10. BEWARE OF HIGH NOISE LEVELS. Some
tractor/implement combinations give noise
levels in excess of 90dB at the operator's ear.
Under such circumstances, ear defenders should be
worn. Keep cab windows and doors closed to
reduce noise level.
Throughout this handbook, the term `tractor' is used to
refer to the power source used to drive the machine. It
does not necessarily refer to a conventional agricultural
tractor.

SAFETY
In addition to the standard safety guidelines listed at the
beginning of this handbook, the following special safety
items apply to the Tomahawk.
1 The machine shall be operated by one person
only.
2 NEVER put your hands inside the delivery
chutes. In the event of a blockage clear it
using the Blockage Removal Tool provided, located
on the front of the lower housing. First, disengage
the PTO, stop the engine, remove the key, and wait
for the rotor to come to rest.
3NEVER enter the bale chamber unless the
PTO has been disengaged, the engine has
been stopped with key removed from the
ignition, and the machine has come to rest.
4 NEVER insert anything inside the chute or bale
chamber while the machine is running.
5DANGER. When entering or leaving the bale
chamber take care, the tailgate surface may
be slippery.
6 Beware of overhead power lines when the
swivel chute deflectors are fully raised. Contact
with power lines could result in the operator receiving
a severe electric shock.
7 Do not climb onto the top edges of the bale chamber
whilst the machine is use.
8 Do not allow anyone to ride on the machine or tractor
linkage or drawbar.
9 Do not allow persons or animals to stand in front of
the outlet chutes whilst the machine is running.
10 Do not operate the tailgate if any person or animal is
standing in the loading area behind the machine,
always ensure good rearward visibility when lowering
the tailgate.
11 Never put your hand over a hydraulic leak. Oil under
pressure may enter the blood stream.
12 The shredding of dusty or mouldy material can
create dust which may have adverse health effects.
Operator exposure to such conditions should be
avoided where possible. When circumstances
prevent this, either use a tractor with a suitable
forced air cab filtration system or an adequate
respirator. Respirators must comply with the relevant
Standard and be approved by the Safety
Inspectorate. Disposable filtering face piece
respirators to EN149 or half mask respirators to
EN140 fitted with filters to EN 143 are likely to be
adequate.
13 Before disconnecting the hydraulic hoses always
lower the tailgate onto the ground for safety reasons
and to avoid residual pressure in the hoses.
14 Always fit the correct size tyre onto the rims when
fitting replacements.
15 Care must be taken when handling large bales, as
they have sufficient weight and density to cause
serious injury. Large bales should be handled with
appropriate machinery either directly into the Tomahawk
or into a position where they can be self loaded. Do not
manually load bales from the stack above the machine,
so as to prevent the risks of falling into the machine and
collapse of the stack of bales.
LEFT AND RIGHT HAND
In this Handbook and Parts List, the terms Left and
Right Hand apply to the machine when viewed looking
towards the rear of the tractor.
USE OF THE TOMAHAWK
The materials shown in table 1 below can be processed
depending on the crossbeater fitted to the machine.
Table 1. Recommended Material
Its use for shredding other materials is not
recommended without first seeking advice from the
manufacturers.
The machine must never be run with the chute
components removed. Unapproved chute modifications
should not be carried out as Safety Regulations may be
infringed.
USE ON THE PUBLIC HIGHWAY
If the machine is to be transported along the public
highway (any road where the public have access)
behind the tractor, it may be necessary to fit lights to
comply with local road traffic legislation, as the machine
is likely to obscure the tractor rear light units.
Suitable lighting kits are available from your local
supplier or may be obtained by contacting Teagle
Machinery Ltd.
The Tomahawk is classed as a trailed implement and as
such does not require brakes when used in the United
Kingdom so long as a maximum speed limit of 20 mph is
observed. For all other countries local regulations must
be observed.
Failure to comply with road traffic legislation may lead to
prosecution by local law enforcement agencies and
could also result in a road traffic accident.

PREPARATION OF THE TRACTOR
For good visibility down both sides of the machine when
working and reversing, the tractor should be fitted with
mirrors.
The PTO power required to drive the Tomahawk is
typically about 60KW (80 HP). However, the suitability
of any particular tractor will depend upon,
a) the distance over which the straw is to be spread
b) the type of bale to be spread.
The machine is designed to use the standard 540 rpm
PTO shaft.
The hydraulic valve block requires a double acting spool
valve or a single acting valve with an unrestricted return.
Whichever is used, the hydraulic supply must be
independent of the 3-point linkage.
FITTING THE MACHINE ONTO THE TRACTOR
Ensure that the clutch end of the PTO Shaft is
fitted to the machine and is supported by the
Drawbar Bracket. Hitch the machine up by the Drawbar.
Switch off the engine and attach the PTO Shaft to the
tractor.
Make sure the Drawbar is securely attached to the
tractor, when loading bales or silage the weight of the
material on the Tailgate may cause the Drawbar to lift.
Check that the lower links are at a height such that they
will not foul the PTO shaft when the tractor is turning. If
they are not used regularly, it is recommended that they
be removed.
Gradually turn the tractor until maximum turning lock is
achieved checking that the PTO shaft does not come to
within 100 mm (4 inches) of bottoming. With the shaft in
its most extended position, there should not be less than
half of the original overlap between the sliding members.
If necessary, cut the PTO shaft to the correct length.
Connect the hydraulic hoses into the spool valve
connections of the tractor. It is important that the supply
hose to the valve is connected to the pressure port of
the tractor, this hose is marked with a red band. Place
the control box / cable control unit in the cab and attach
it to the auxiliary socket.
It is essential to get the relationship between the tractor
PTO shaft and the gearbox input shaft correct to give a
satisfactory PTO shaft life. The correct geometry exists
when the machine is horizontal, see Figure 1.
If the machine is shredding whilst turning on a regular
basis it is recommended that a PTO shaft with a wide
angle, constant velocity joint be fitted.
Figure 1. Correct PTO Geometry.
FITTING THE CONTROL BOX ONTO THE TRACTOR
CONTROL BOX
Supplied with the machine is a control box mounting
plate. This should be fitted in the cab in a suitable
position that is convenient to the operator ensuring the
cab structure is not drilled, welded or damaged.
To reverse the bracket, remove the mounting bolts
beneath the Control Box lid and re-position the control
box. Make sure the seal is in correct position when
reassembling.
A 7.5 amp blade type fuse is fitted in the supply cable
of the Control Box. If the connector provided on the
supply lead is not to be used, it is essential that the 7.5
amp fuse is retained to prevent damage resulting from
current overload.
If the supply cable is connected with the incorrect
polarity the Control Box will not turn on.
MACHINE CABLE
Once the Control Box has been positioned, route the
Machine Cable into the cab making sure it is kept away
from the rear wheel and any pinch points between the
PTO shaft and link arms. Where possible, route into the
cab through cable entry points on the tractor, allowing
the rear window to be kept closed during use. Plug the
cable connector into the socket on the Control Box and
secure using a retaining clip.

6
OPERATION
The machine is fitted with a 2-speed Gearbox. For
blockage free operation it is important that the
correct gearbox speed is selected for the material
being shredded.
The gearbox has a neutral position, make sure the
required gear has been properly selected. If operated in
neutral, material will enter the Rotor Housing possibly
resulting in a blockage. Make sure all material is
removed before restarting the rotor.
For shredding straw and other dry materials either rotor
speed may be used. For maximum throw distance the
handle should be moved towards the position marked by
the Hare to give a 1:1 ratio.
For shredding silage and other wet materials it is
recommended that the slow rotor speed is used as long
throw distances are not usually required and wastage is
reduced. To set the slow rotor speed the gearbox handle
should be moved to the position marked by the Tortoise
to give a 1.85:1 ratio.
To achieve maximum throw distance, operate the
tractor engine at PTO speed. For reduced throw
distances operate the tractor at reduced engine
speeds, as per Table 1. Very slow rotor speeds may
cause blockages.
Table 1. Gearbox & PTO settings - right hand chute.
The valve block includes a flow control valve to vary the
rotational speed of the bed chain. A rotational speed of
the Bed Chain speed indicator of approximately 15 rpm
is required for the shredding of rectangular bales and
dispensing clamp silage. For round bales, indicator
speeds of up to 30 rpm may be used to improve the
feed rate.
DUAL CHOP OPERATION
Dual Chop machines can not chop Silage.
The Sliding Blade Carrier is controlled through the
hydraulic spool valve. Slots located on the front of the
machine indicate the engaged / disengaged positions of
the Sliding Blade Carrier, yellow for disengaged.
When a long chop length is desired raise the Blade
Carrier disengaging the blades.
When a fine chop length is desired lower the Blade
Carrier to engage the blades against the Crossbeater.
Before lowering the Blade Carrier, stop the Bed Chain
and wait for the material to stop flowing into the Rotor.
BALE RESTRAINT BEAM
The Bale Restraint Beam is factory set in the most
desirable position. If problems occur with excessive
breaking of Shear Bolts, it may be advisable to adjust
the Bale Restraint Beam backwards by one hole.
SWIVEL CHUTE
The Swivel Chute rotates through 270 degrees and can
be operated in any position.
To deliver silage close to the machine position the
Chute so that material is passed onto the Feed
Passage Slide. The position of the Slide can be
adjusted as desired.
Alternatively the material feed direction can be
controlled by the Chute. It may be necessary to rotate
the Chute fully to deliver material alongside the
drawbar.
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.
BED CHAIN OPERATION
The Bed Chain is operated by pressing forward button to
move forwards, pressing forward button to stop, and
pressing and holding reverse button to reverse. It is not
necessary to stop the Bed Chain before pressing the
reverse button as this will automatically cancel the
forward direction before engaging reverse.
COMMENCING OPERATION
LOADING THE MACHINE
The strings or net should be removed from the bale as it
is being loaded into the machine. The Tomahawk will
shred some string but some will tend to wrap around the
Crossbeater. Putting twine or netwrap through the
machine is not recommended as it will eventually be
spread on the land, polluting future crops.
Bales can be loaded into the machine in two ways, by
using a loader or by self-loading using the machine
Tailgate. If a loader is used, simply load the bale into
the Bale Chamber so that it is fully inserted. Ensure the
bale is not rammed against the crossbeater. With
square bales it is recommended that the bales are laid
on their side to aid string removal.
When loading the machine, avoid running the Bed
Chain without the rotors turning. If there is a large
amount of material still in the Bale Chamber it will be
placed into the Rotor Housing causing the Rotor to jam
at start up.
Do not stand above the machine on a stack of bales
or in a barn to load the machine manually.
When removing string or netwrap from bales never
climb into the bale chamber or onto the tailgate
behind a bale unless, the PTO has been disengaged,
the engine has been stopped, the key removed from the
ignition and the machine has come to rest.
The Tailgate is designed to load bales into the Bale
Chamber of the machine. For large rectangular bales
place the bale on the ground with one end against a
solid object. For easy removal of the strings place the
bale on its side so that the strings are not in contact with
the ground. Reverse the machine with the Tailgate
lowered until the bale slides up the Tailgate and into the
Bale Chamber. Raise the Tailgate until it is in a
horizontal position and engage the Bed Chain to move
the bale fully onto the Tailgate.

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.

MAINTENANCE
Never enter the bale chamber unless the PTO has
been disengaged, the engine has been stopped,
the key removed and the machine come to a 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.
BLADES
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 heavy duty leather gloves, and
work slowly and methodically.
SILAGE CROSSBEATER BLADES
Enter the Bale Chamber via the Tailgate. Wedge the
Crossbeater and the Rotor to prevent them from turning
and pinching hands and fingers between the Bale
Restraints Fingers and the Crossbeater.
Cover areas of the Crossbeater 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 themselves will require replacing
altogether.
To achieve further cutting aggression, a selection of
Blades can be positioned using the outer holes on the
Crossbeater rings.
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 ¾”
diameter holes in the Slides.
Remove the M12 bolt (1) from the Cover Plate located
on the LH Mid Body Panel, as indicated in Figure 4.
Figure 4. Cover Plate closed position, bolt removal.
Rotate the Cover Plate and position as shown in Figure
5.
Figure 5. Cover Plate open, bolt and boss removal.
Remove the Blade Bar Boss (2) by undoing the M12 bolt
(3), illustrated in Figure 6. Using the Blockage Removal
Tool, which is stored on the front of the machine, slide
out Blade Beam by hooking the Boss hole.
To obtain fresh cutting edges on the Blades, the Blade
Beam can be fully removed from the machine and
replaced in the opposite direction.
After the Blade Beam has been inserted back into the
machine, replace the Blade Bar Boss but do not tighten
the M12 bolt, this allows the blade position to be
adjusted. Check the Blade clearances on the
Crossbeater by lowering the Sliding Blade Carrier. Align
the Blades centrally between the Crossbeater Rings by
adjusting the Blade Beam Tension Bar on the Sliding
Blade Carrier. Finally tighten the M12 bolt securing the
Blade Bar Boss.
Once both edges of the Blades have become blunt the
individual knives themselves will require replacing. Do
this using a 13mm ring spanner and an allen key, both
with long handles, this will allow the bolts to be removed
whilst avoiding contact with the sharp edges of the
Blades.

BED CHAIN
To tension the Bed Chain, release the front lock nut on
the Bed Chain Tensioner and jack the mounting bush
using the other nut. The Bed Chain should be tensioned
such that the chain can be lifted 50mm above the bed
midway between the drive sprockets. Retighten the lock
nuts.
After tensioning the Bed Chain the position of Rear
Sprocket Scrapers must be altered. To adjust slacken
the nut on the outside of the body. Slide the Scraper
towards the Chain Wheel so that it runs tightly against
the bottom of the groove in the centre of the Chain
Wheel, retighten the nut, see Figure 6. Repeat
procedure on the opposite side of the machine.
If the Bed Chain becomes tight in use, check that the
grooves in the Chain Wheels have not become tightly
packed with straw or silage. If they have they need
clearing and the Scrapers will require repositioning.
Figure 6. Sprocket Scraper position.
If the area beneath the Bed Chain becomes blocked or
requires attention, remove the bolted Inspection Panel
underneath the machine and clear the blockage.
Check the Front Scrapers for excessive wear, these
may require replacing over time.
BALE RESTRAINT BEAM ADJUSTMENT AND
REMOVAL
To adjust the Bale Restraint Beam remove the two M12
bolts located in the holes on both sides of the Restraint
Beam, and loosen the third bolt in the slot. Reposition
the Bale Restraint Beam by aligning the necessary
holes, replace and tighten bolts.
To remove take the weight of the Bale Restraint Beam
using a suitable lifting device. Remove the 3 bolts from
each end before extracting the Bale Restraint Beam
itself.
Refitting is the reverse of above.
DUAL CHOP SIEVE REMOVAL
Raise the Blade Beam and lock it in the upper position
by entering the Bale Chamber and sliding two bars
through the ¾” diameter holes in the Slides.
Remove the Bale Restraint Beam as detailed
above.Remove the six M10 bolts that hold the sieve to
the Mid Body Panels. Remove the six cup squares
retaining the screen to the support beam. The Sieve
can then be removed by rolling it over the Crossbeater.
Refitting is the reverse of the above.
CROSSBEATER SHEAR BOLTS
To replace the shear bolt, open the left hand Hinged
Drive Chain Guard to gain access to the Shear
Sprocket. Grease the Sprocket Hub before replacing
the Shear Bolt with a Shear Bolt of the correct grade.
Shear Bolt Grades: Silage Machine - 10.9 M8 x 50
Dual Chop Machine - 8.8 M8 x 50
GEAR BOX
Check the oil level in the Gearbox daily.
After 50 hours of use the Gearbox oil should be drained
and replaced with new oil. To drain the oil, remove the
Valve Guard, remove the drain and filler plugs and allow
it to empty. Waste oil should be collected and disposed
of at an oil recycling facility.
Refill the Gearbox with SAE90.EP Gearbox oil. The oil
capacity of the Gearbox is 4.7ltrs (1.25 Gallons).
DRIVE CHAINS
Apply chain lubricant or oil weekly to these chains.
To tension the Bed Chain Drive, remove the Chain
Guard on the right hand side of the machine, release the
4 clamp bolts on the Motor Mounting Plate. Using the
tensioning bolt provided jack the motor mounting plate
until the chain has 12mm movement midway between
the Sprockets, see Figure 7.
To tension the Crossbeater Chain Drive open the
Hinged Drive Chain Guard and loosed the four bolts
retaining the Layshaft. Slacken the clamp bolt on the
Layshaft universal joint. Slacken the M16 locking nut
on the tension bolt and tighten the tension bolt until
there is 15mm deflection midway between the
Sprockets, see Figure 7. Tighten the tension Bolt
locking nut and the four Layshaft bearing retaining
nuts. Tighten the Layshaft universal joints clamping
nut and bolt before finally closing the Chain Guard.

HYDRAULIC VALVE
Before attempting to dismantle any of the hydraulic
system, the Tailgate and Deflectors must be fully
lowered to prevent injury from the unexpected
lowering of these components.
If Contamination of the oil occurs then this can result in
failure of the hydraulic circuit. An inline pressure filter is
available if oil contamination is regularly happening.
Where a inline pressure filter is fitted, the element
should be replaced annually. To replace the element,
remove the guard covering the hydraulic valve on the
front right of the machine and unscrew the filter canister.
Replace element, retighten canister, pressurise the
system, inspect for any leaks from canister and fit valve
guard.
If problems are experienced with either the hydraulic
system or electric controls, please contact Teagle
Machinery Ltd. for advice as a separate manual is
available to cover troubleshooting and repair
SLIP CLUTCH
If the clutch slips repeatedly for no apparent reason
there are a number of things to be checked:
Firstly check that the clutch linings do not show signs of
damage or excessive wear. If so, they should be
replaced. When new they are 3mm, (1/8") thick.
Make sure that the compressed spring length is set to
give the correct torque setting – see PTO shaft parts list.
If the clutch continues to slip it should be adjusted as
follows.
1. Remove the guard fitted to the Rotor Gearbox.
2. Fit the PTO shaft with the Slip Clutch at the machine
end.
3. Insert a piece of wood through the Discharge Chute
and position it such that it prevents the Rotor from
turning.
4. Insert a steel bar through the rear PTO yoke and use
a spring balance to obtain the correct torque setting.
The clutch should just slip at a torque of 1200 Nm
(900 lbft) - equal to a force of 1000N at 1.2m (225 lb
at 4ft) from the centre of the yoke. Adjust the Clutch
as necessary using the eight spring loaded clamp
bolts. (Slip clutch is set to minimum torque setting
when manufactured)
WHEEL REPLACEMENT
If it is necessary to remove a Wheel, place a jack
underneath the Axle Beam, loosen the wheel nuts and
raise the machine until the Wheel can be removed.
Place an axle stand underneath the machine before
removing the Wheel. Refit the Wheel and tighten the
wheel nuts.
WHEEL NUTS
Before using a new machine and daily during use, check
the wheel nuts are tight. The recommended torque for
the 6 Stud Wheel is 400Nm (320lb.ft).
Once the nuts are allowed to work loose, it may be
impossible to keep them tight and new nuts and studs
will be required. In extreme cases, damage to the wheel
rims and hubs may result.
TYRE PRESSURES
Check tyre pressures regularly, inflating to the pressures
shown in the following table. Over inflation can be
dangerous.
Table 2. Tyre Pressures.
LUBRICATION
Good quality semi-solid grease should be applied to the
following grease points:
Table 3. Lubrication Schedule
The above frequencies are based on typical daily use for
bedding & feeding purposes. Continuous use for special
applications may necessitate more frequent lubrication.
To gain access to PTO shaft joints, use two flat ended
screwdrivers to release the clips in the plastic guard.
The guard cone can then be pulled back to allow
access, this is shown in Figure 8. To reassemble, align
the clips with the two tabs on the inner ring, push the
cone back towards the PTO shaft joint, the guard cone
will snap back into position.

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.
