PICTOGRAMS

3. SAFETY
In addition to the standard safety guidelines listed at the
beginning of this handbook, the following special safety
items apply to the Tomahawk.
3.1 The machine shall be operated by one person
only.
3.2 NEVER put your hands inside the delivery
chutes. In the event of a blockage clear it
using the tool provided (stored at the front of the
machine). First, stop the engine, remove the key,
disengage the PTO and wait for the rotor to come to
rest.
3.3 NEVER enter the bale chamber unless the
engine has been stopped the key removed,
the PTO disengaged and the rotor come to
rest.
3.4 NEVER insert anything inside the chute or bale
chamber while the machine is running.
3.5 DANGER. When entering or leaving the bale
chamber take care, the tailgate surface may
be slippery.
3.6 Beware of overhead power lines when the
swivel chute deflectors are fully raised, contact
with power lines could result in the operator
receiving an electric shock.
3.7 Do not climb onto the top edges of the bale chamber
whilst the machine is use.
3.8 Do not allow anyone to ride on the machine or
tractor linkage or drawbar.
3.9 Do not allow persons or animals to stand in front of
the outlet chutes whilst the machine is running.
3.10 Do not operate the tailgate if any person or animal
is standing in the loading area behind the machine
and always ensure good rearward visibility when
lowering the tailgate.
3.11 Never put your hand over a hydraulic leak. Oil
under pressure may enter the blood stream.
3.12 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.
3.13 When rotating the chute always check the
clearance between the chute and the rear of the
cab, particularly the window if it is open.
3.14 Before disconnecting the hydraulic hoses always
lower the tailgate onto the ground for safety and to
avoid residual pressure in the hoses.
3.15 Always fit the correct size tyre onto the rims when
fitting replacements.
3.16 Care must be taken when handling large
bales since they have sufficient weight and
density to cause serious injury or death. For this
reason never attempt to manually load bales from
the stack above the machine. Large bales should
be handled with appropriate machinery either
directly into the Tomahawk or into a position where
they can be self loaded.
4. 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.
5. USE OF THE TOMAHAWK 1005/1010
Each machine can be used to shred the materials as
recommended in table 1 below.
Table 1. Recommended Materials
Its use for shredding other materials is not
recommended without first seeking further advice from
Teagle Machinery Ltd.
The machine must never be run with any of the chute
components removed or modified. The machine may
then become in breach of safety standards which are
there for your safety.
6. USE ON THE PUBLIC HIGHWAY
6.1 United Kingdom
It is necessary to fit a road lighting kit to comply with
highways regulations.
Suitable lighting kits are available from Teagle
Machinery Ltd through your local Teagle dealer/
distributor
The Tomahawk is classed as a trailed implement and
requires brakes when used on the public highway, the
maximum speed limit of 20mph for tractors and trailed
appliances must be observed.
6.2 Export Countries
Please contact the relevant government department to
ensure local regulations are complied with.
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.
7. PREPARATION OF THE MACHINE
Remove the PTO shaft and any other loose items from
the body of the machine.

Material 1005 1010
Baled Silage Yes No
Baled Hay Yes Yes
Baled Straw Yes Yes
Clamp Silage Yes Yes

8. 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 (80HP) for the 1005 and 67.5 KW
(90HP) for the 1010. 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, and c) whether the machine is to be used to
transport bales along the road.
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.
The control box mounting bracket should be fitted inside
the cab so that the controls are conveniently situated for
the operator. It should be remembered that structural
members of the cab must not be drilled or welded.
The electric control supply cable should be connected
the tractor’s auxiliary 3 pin socket. Should a socket not
be available then the control box must be wired directly
to the battery. Remove the connector plug to reveal the
brown and blue wires, brown is positive, blue is
negative. Wire directly to the battery with a suitable lead
and insulated connectors.
If the supply cable is connected to the battery with
the wrong polarity the control desk will not power
up.
If the fuse should blow this will be indicated by the red
LED illuminating.
Under no circumstances remove the fuse holder or
use fuses with a higher rating than 7.5amps.
Warranty will be invalidated
9. FITTING THE MACHINE ONTO THE TRACTOR
Check that the lower links are at a height such that
they do not foul the PTO shaft when the tractor is
turning. If they are not used regularly, it is
recommended that they be removed. Hitch the machine
to the tractor via the drawbar without the PTO shaft
fitted. Release the parking brake on the left hand side of
the machine by pulling forwards and then allow to swing
rearwards. Park the tractor and machine securely on
level ground and remove the key.
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.
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. A
shaft of this type can be obtained from the manufacturer.
The PTO shaft will require cutting to length to suit the
tractor to remove the risk of bottoming resulting in
catastrophic failure of the machine gearbox.
Proceed as follows:
1.) Measure the distance between the annular groove
on the tractor output shaft to the annular groove on the
machine input shaft.
2.) Measure approximately the distance between the
retaining balls of each sliding yoke at either end of the
PTO shaft with it fully collapsed.
3.) Subtract the second measurement from the first and
now subtract this value from 150mm (6”). The answer is
the amount to be removed from each half of the PTO
shaft.
4.) Separate the 2 halves of the PTO shaft and remove
the necessary amount from each half guard and each
half tube. Remove the guards to facilitate cutting if
required.
5.) Fit the slip clutch side of the PTO shaft to the
machine and the other end to the tractor, the PTO shaft
should now have the required 150mm (6”) travel before
bottoming. This should be indicated by the length of
black PTO guard showing.
6.) 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.
7.) Drive the tractor and machine over any significant
undulating ground conditions checking that the PTO
shaft does not come to within 100 mm (4 inches) of
bottoming.
Connect the hydraulic hoses into the spool valve 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 red tape around the hose. Attach the
brake hose to the tractor brake coupling
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 box
and lock by the clamp provided.
Ensure the functions of the control box are
completely understood before proceeding to use
the machine. In particular the bed chain is actuated in
the forward direction by pushing the forward direction
button and stopped by pressing the button again.
Reverse of the bed chain can only be actuated by
holding the reverse button.
10. OPERATING INSTRUCTIONS - LOADING
10.1 General
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 crossbeaters. Putting twine or
netwrap through the machine is not recommended as it
will be eventually spread on the land and polluting
subsequent crops.
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 and the
machine come to rest.
5

Bales can be loaded into the machine in two ways, using
a loader or by self-loading using the machine tailgate. If
a loader is used, simply load the bale into the bale
chamber such that it is fully inserted, but do not ram it
against the crossbeaters.
When loading the machine, it will be necessary to
run the bed chain to help self load the bale into the
chamber. However, excessive use of the bed chain for
this purpose may cause material to enter the rotor
housing resulting in a blockage during machine start up.
The tailgate is designed to load bales into the chamber
of the machine. Where a telescopic tailgate is fitted, it is
important to only self load with it in the retracted
position.
To retract the tailgate:
1.) Lower the tailgate.
2.) Switch off the tractor and remove the key.
3.) Remove the extension retaining bolts.
4.) Slide the rear tailgate section towards the machine,
replace the retaining bolts in the retracted position.
Figure 1. Telescopic Tailgate Setting
10.2 Self Loading
Make sure the drawbar is securely attached to the
tractor as self loading may cause it to lift.
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. In the
case of quadrant bales, place the bale with the knots on
the top. Reverse the machine with the tailgate lowered
until the bale slides up the tailgate into the bale
chamber. Raise the tailgate until it is horizontal and
engage the bed chain to move the bale fully onto the
tailgate.
Make sure that the bale is not forced against the
crossbeaters as this may cause problems when
starting the machine.
Before removing the strings, place the posts in the
sockets on the tailgate and put the chain around the rear
of the bale to avoid the risk of crushing from unsecured
material.
To load round bales, reverse the machine under the
bale so that the bale rests against the tailgate. Lift the
tailgate slightly and drive forward a short distance before
raising the tailgate further. With the bale on the tailgate
cut the strings or netwrap on the machine side of the
bale as low as possible and remove around the top of
the bale. Rope hooks are positioned on the underside of
the tailgate to tie partially removed twine and netwrap to.
Raise the tailgate, the bale will roll into the machine
leaving the twine or netwrap tied to the tailgate allowing
easy removal.
10.3 Multiple Bale Loads
The Tomahawk 1005/1010 are large machines designed
to carry several bales in a load. To maximise the
carrying capacity of the machine it is recommended that
the telescopic tailgate be extended as per Figure 1. A
suitable mechanical loader should now be used for
loading. The machine is now capable of handling two
large rectangular bales 1.2x1.3x2.7m or three 2m round
bales as shown in figure 2 below.
Figure 2. Tomahawk T1005/T1010 Loaded
10.4 Bale Lift
In certain territories (not UK) the machines are available
with a bale lift in the body of the machine to permit a
portion of the load to be lifted from the bed chain. This
can be advantageous in reducing the amount of
material presented to the crossbeaters ensuring smooth
discharge. Operation of the bale lift is by means of the
chute selection buttons on the bottom left of the control
box. When fitted, the feature should be used as shown
in figure 3 below.
Figure 3. Bale Lift Use
6

10.5 Clamp Silage
When loading clamp silage, lower the tailgate slightly to
give a larger body capacity. The hydraulic oil pressure
required to rotate the bed chain will be determined by
the quantity of silage loaded. The machine requires
operating pressures of 120 bar (1750 psi.) when the
body is filled with clamp silage.
11. OPERATING INSTRUCTIONS - DISCHARGE
11.1 Gearbox Speed Selection
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
discharged as per table 2 below. The gearbox has a
neutral position, so make sure the required gear has
been properly selected so as not to block the rotor
housing.
Table 2. Recommended Rotor Speed
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 between PTO and discharge
rotor speed.
For shredding silage and other wet materials it is
recommended that the slow rotor speed be used since
long throw distances are not usually required 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. The machine may be used at reduced PTO
speeds and still deliver material to the desired position.
Very low PTO speeds should be avoided as a blockage
in the rotor housing may result.
11.2 Right Hand Chute
Adjust the position of the chute to deliver the material
being spread in 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 300 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 Engaging PTO
Engage the PTO with the tractor engine on low idle and
increase the speed rapidly to working speed when the
clutch has engaged fully.
11.5 Before Commencing Discharge
If the machine is loaded to capacity, i.e. material other
than clamp silage is supported by the tailgate, the
tailgate must remain horizontal until the material in the
body has been discharged. This is necessary to allow
the material within the body of the machine to rotate
freely once it comes into contact with the crossbeaters.
No attempt should ever be made to force material
towards the crossbeaters using the tailgate. With the
bed chain speed control on the control box on zero,
engage the tractor spool valve and 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.
11.6 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 4 below.
Figure 4. Rotation Of Square Bales
Where a bale lift is fitted, release the portion of the bale
retained only when the first portion has been discharged
which is usually indicated by a large fall in discharge
rate.
Once the material in the bale chamber has been
discharged the tailgate can be lifted to allow the second
bale (or a portion of) to be loaded into the chamber. 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 in the first
instance.
11.7 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 5 overleaf.
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
7

be indicated by a build up of material above the bale
restraint.
Figure 5. Rotation Of Round Bales
11.8 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.
11.9 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
crossbeaters before commencing 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
crossbeaters. This allows the material in the area
around the crossbeaters and rotor to be blown clear of
the machine. Failure to do this may result in a blockage
occurring when the machine is re-started.
The length of chop will vary with the condition of the
bale. The evenness of feed and power consumption will
also vary with the material being shredded. In general,
baled silage and damp or caked straw materials will
require a higher power input than dry brittle materials.
Should the rotor or crossbeaters become blocked
indicated by either slipping of the PTO clutch or failure of
the crossbeaters 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.
12. MACHINE PROTECTION DEVICES
IMPORTANT: The machine is fitted with a shear bolt on
the cross beater drive line. After a blockage, the bolt
may need replacing. If the bolt has failed grease must
be applied to the slipping surfaces via the grease nipple
before the shear bolt is replaced.
IMPORTANT: The machine is fitted with a slip clutch on
the PTO shaft. If this slips repeatedly, it should not be
tightened until the machine has been examined to check
that there is no fault or blockage. Refer to 'Maintenance'
for the correct clutch setting.
The slip clutch may be hot. Care should be taken
when removing it from either the machine or tractor.
13. MAINTENANCE
13.1 Safety
Never climb into the bale chamber or onto the
tailgate unless the PTO has been disengaged. The
engine has been stopped, the key has been removed
and the machine has come to a rest.
Care must be taken when carrying out any
maintenance on / around the chopping blades as
they are extremely sharp. Leather gloves will give some
protection against minor cuts.
13.2 Blades
When carrying out maintenance work on the blades
enter the bale chamber via the tailgate. Wedge the rotor
and crossbeaters to prevent them from turning reducing
the risk of trapping hands between the knives and bale
restraint fingers. When replacing knives use spanners
with long handles which will allow the bolts to be
removed whilst avoiding contact with the sharp edges of
the knives.
Always keep your hands away from the edges of
blades - particularly new ones, as they are
extremely sharp. The blades have a sharp trailing edge,
which remains sharp even when the leading edge is
blunt.
13.3 Bed Chain
To tension the bed chain, release the front lock nut on
the tensioner and jack the tensioner 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 lock nuts after tensioning.
The chain tension must be checked and adjusted
after initial use as bedding in shall occur.
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 condition of the Scrapers needs to be
checked.
If the area beneath the Bed Chain becomes blocked or
requires attention, remove the bolted Inspection Panels
underneath the machine and clear the blockage.
Check the Front Scrapers for excessive wear, these
may require replacing over time.
Figure 6. Sprocket Scraper Position
13.4 Crossbeater shear bolt
To replace the shear bolt, open the hinged LH drive
chain guard. The shear bolt is on the lower crossbeater
shaft. Grease the hub before replacing the shear bolt
with a Grade 10.9 M8 x 50 bolt.

13.5 Gearbox
After 50 hours of use the gear box oil should be drained
and replaced with new oil. To drain the oil, remove the
PTO shaft and guard cone 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 to the level plug with SAE90.EP
gearbox oil. The oil capacity of the gearbox is 4.7ltrs
13.6 Drive Chains
Apply chain lubricant or oil weekly. The chains should be
tensioned so that there is 12-13mm (1/2”) deflection at
the mid span point as indicated in figure 7 below.
Figure 7. Chain Deflection
To tension the crossbeaters drive chains, open the
hinged chain guard on the left hand side of the
machine. For the lower beater drive, slacken the
layshaft bearing bolts and tensioner locknut. Increase
tension by jacking the bearing as required until the
correct tension condition is met. Retighten all nuts. For
the upper crossbeater slacken the tensioner roller
mounting bolt in the centre of the roller and turn the
tension screw on the adjuster clockwise until the
correct tension condition is met. Retighten the roller
mounting bolt.
13.7 Swivel Chute
The chute is rotated by means of a gear and ring gear.
It is important that this is well greased. To apply grease
to the ring gears there are 4 grease nipples on the
mounting flange.
The deflector ram has 2 grease nipples, one on each
pivot bush.
13.8 Hydraulics
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.
The hydraulic system is protected from contamination by
an inline pressure filter. Periodically the element should
be checked for contamination and it is recommended
that the element be replaced at least once 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 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.
13.9 PTO 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.
Also 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 lb.ft.) - equal to a force of 1000N. at 1.2 metre
(225 lb. at 4 feet) from the centre of the yoke. Adjust
the clutch as necessary using the eight spring loaded
clamp bolts.
13.10 Lubrication
Good quality semi-solid grease should be applied to the
following grease points:
The above lubrication frequencies are based on typical
daily use for bedding & feeding purposes. Continuous
use for special applications may require more frequent
lubrication.

13.11 Wheel Nuts
Before using a new machine and daily during use, check
the wheel nuts are tight. They should be torqued to a
value of 400Nm (320 lb ft).
Once the nuts are allowed to work loose, it may be
found impossible to keep them tight and new nuts and
studs will be required to overcome the problem. In
extreme cases, damage to the wheel rims and hubs
may result.
13.12 Tyre Pressure
Check the tyre pressures regularly inflating them to the
pressures in table 3 overleaf as required.
Table 3. Tyre Pressures
13.13 Replacing Wheels
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.
13.14 Electric Controls.
The electric controls require no maintenance and it is
imperative that no part of the system is ever sprayed
with a moisture repelling agent such as WD40.
If a malfunction of the system occurs, please contact
Teagle Machinery Ltd or an authorised dealer/distributor
for advice.
13.15 Handbrake Adjustment
With reference to figure 8 below, the handbrake can be
adjusted by releasing the locknut (item 1) and increasing
tension by means of the tension nut (item 2). If
maximum travel is reached then the clamp (item 3) can
be released and the rope adjusted accordingly.
Figure 8. Handbrake Adjustment
13.16 Service Brake Adjustment
It is imperative that the brakes are adjusted
correctly to meet the requirements of the current
braking regulations. As the brake shoes wear, it may be
necessary to realign the actuating rods on their splines
so that the arms are perpendicular to the ram body.
13.17 Removal Of Main Rotor
The rotor can only be released from the main gearbox
with the application of service tool SC3776 available
from the manufacturer.
14. OPTIONAL EXTRAS
14.1 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.
15. MACHINE STORAGE
When the machine is not being used it is
recommended that the control box be stored safely
away from the machine in a dry location. The electrical
connections together with hydraulic hoses should be
stored in the positions provided on the layshaft guard
on the front right of the machine. If the machine is to
be laid up for any great length of time it should be
thoroughly cleaned down and any bright surfaces
treated with paint as opposed to a rust preventative
since the machine is used for dispensing foodstuffs. All
lubrication points should be attended to ready for
subsequent reuse.
16. 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.
