Notes:
(1) Spearhead Machineryconstantly reviews and improves product designs and reserve the right to change
this information. As a consequence actual machines may vary from specification. Contact your Spearhead
Sales representative if you have any queries.
(2) This specified geometric maximum is stated for information purposes only. It does not imply that it is safe or
appropriate to cut material in this position. The actual safe maximum side cut height will depend on the
width of the tractor that the implement is mounted to.
(3) The transport width quoted is a half width and is measured to the PTO centre which is notionally assumed
to be on the tractor centreline. As a consequence the full on road width is the quoted transport width plus
half the tractor width plus (or minus) any mounting offset from the tractor centreline.
(4) The transport depth is indicative and will vary with the specified tractor. This figure assumes a reference
dimension of 766mm between axle centre and lower link pin centre.
(5) All dimensions are determined from computer models. As a result actual measurements mayvary as a
result of deflections due to weight. Tractor tyres will naturally compress on the working side of the tractor as
the centre of gravityshifts. The amount is affected bytyre construction, age, inflation pressures and the
use of local ballast weight. For example a 20mm compression of the cutting side rear tyre will be magnified
by the offset reach which will have an effect on the actual cut height.

2 Safety
2.1 Safe operation
This user manual should be considered as part of the machine. The operator should read the following pages carefully
and become familiar with the contents before starting work. Familiarity with the instruction manual is an essential part of
training for a competent user. Operators must be competent and fully capable of operating this machine safely and
effectively before attempting to use it in a public place.
Every employee should receive regular training on how to use this machine (at least once a year), in accordance with
the guidelines published bythe employer's insurance. Untrained or unauthorized personnel must not use this machine.
In the interest of safety, please make sure that the instructions mentioned above are made known to all your
employees who must use the equipment. We recommend that the use of this equipment be limited to qualified
operators. Persons under the age of sixteen must not use the machine and must stay away from the place where they
are used.
2.2 Safety warnings
The operator must read, understand and follow all of the Safety instructions. Serious injury or death mayoccur unless
care is taken to follow the warnings and instructions provided. The level of safetyis indicated in three levels and the
following notation is used throughout this operator instruction book;
DANGER! Level 1; alerts for imminent death or critical injury.
WARNING! Level 2; warns of serious injury or possible death.
CAUTION! Level 3; indicates possible injury.
Never operate the tractor or machinery until you have read and completely understand this manual and the tractor
operator’s manual and each of the safety messages found in the manuals and those displayed on the tractor and
implement.
DANGER! DO NOT attempt anymaintenance of or adjustment to the machine while it is running. Before
carrying out any work on the machine follow the three safety instructions below:
PUT THE PTO OUT OF GEAR
STOP THE TRACTOR ENGINE
LOWER THE CUTTING UNIT ON TO THE GROUND
DANGER! At all times ensure that the PTO shaft guard is in position, securelyfitted and in good condition and
that the tractor PTO shaft shield is fitted. Always replace any damaged guards and shields.
DANGER! Do not enter the working zone of the PTO shaft. It is dangerous to approach the rotating parts of
the machine.
DANGER! Before maintaining and working on the machine always stop the tractor, switch off the tractor
engine, remove the ignition keyand remove the PTO shaft. Do not work under anymachine raised on
hydraulics unless it is supported bya solid safety support.
DANGER! Never clean or adjust PTO driven equipment with the tractor engine running. Kill the engine and
pocket the keybefore attempting any maintenance on the machine.
DANGER! All guards, bands, deflectors, driveline shields and gearbox shields should be used and maintained
in good working condition at all times. Theyshould be carefullyinspected daily for missing or broken
cable, chain links, shields or guards. Missing, broken or worn items must be replaced before
attempting to use the machine to reduce the possibility of injury from thrown objects or entanglement.
DANGER! Keep a careful watch for passers-by who may inadvertently get in the way of cut material being
thrown from the machine. These machines are capable under adverse conditions of throwing objects
great distances at high velocity. Stop the blades until all people are well clear.

8999129: v1 11/09/2018
Page 2.2 of 2.9 pages Original instructions (ENGLISH)
Website: www.spearheadmachinery.com
DANGER! AVOID WIRE. It can be extremelydangerous if wire catches in the blades of the machine, and
every care must be taken to ensure this will not happen. Inspect the working area before
commencing. Remove all loose wire and obstructions and clearly mark those that are fixed so that
you can avoid them. Any unusual noise from the cutting unit area indicates that the blades may have
been fouled by an obstruction. A visual indication that wire has become entangled may be a sudden
movement of the vegetation ahead of the machine. In any such event STOP the tractor engine
INSTANTLY. On no account move the machine until blades have completelystopped. NEVER
UNDER ANY CIRCUMSTANCES run the machine in reverse to 'clear itself'. When the machine has
stopped, inspect it and remove any obstruction that may be present. If working under a raised
machine, ensure that it is safelysupported. Before working on the machine always stop the tractor
engine and remove the ignition key.
DANGER! These machines are capable under adverse conditions of throwing objects great distances at high
velocity. CHECK the blades for wear and the attachment bolts for tightness every day during work. A
few moments whenever the machine is stopped (e.g. whenever removing obstructions) will help
reduce blade wear or loss.
DANGER! ANY UNUSUAL NOISE from the cutting unit area indicates that the blades mayhave been fouled
by an obstruction. A visual indication that wire has become entangled may be a sudden movement of
the vegetation ahead of the machine. In any such event STOP the tractor engine INSTANTLY. On no
account move the machine until blades have completely stopped. NEVER UNDER ANY
CIRCUMSTANCES run the machine in reverse to 'clear itself'. When the machine has stopped,
inspect it and remove any obstruction that maybe present. If working under a raisedmachine, ensure
that it is safely supported. Before working on the machine always stop the tractor engine and remove
the ignition key.
DANGER! Do not operate with wings raised off the ground. Operating with the wings raised exposes the
blades and can cause objects to be thrown and there is also danger of entanglement in or being hit by
rotating blades.
DANGER! Never transport the machine or attempt maintenance with the blades running. Serious injury or
even death can result from contact with rotating blades.
DANGER! Keep your forward speed to a level appropriate to the operating conditions. High-speed
manoeuvres are verydangerous, particularly on uneven ground where there is risk of overturning.
DANGER! When the wings are folded for transport, the centre of gravity is raised, and the possibility of overturn
is increased. Turn slowly and with extra care on hillsides. Overturning the mower could cause the
mower to overturn the tractor and vice versa. Never fold wings on a hillside, the mower may overturn
DANGER! Be particularly careful in transport. Turn curves or go up hills only at a low speed and at a gradual
steering angle. Ensure that at least 20% of the tractor’s weight is on the front wheels to maintain safe
steering. Slow down on rough or uneven surfaces.
DANGER! DO NOT carry passengers on either the tractor or the mower - falling off can kill.
DANGER! Do not mount or dismount the tractor or machine while it is moving. Mount or dismount only when
stopped –falling off can kill.
DANGER! Do not operate this Equipment with hydraulic oil leaking. Oil is expensive, and its presence could
present a hazard. Do not check for leaks with your hand! Use a piece of heavy paper or
cardboard. High-pressure oil streams from breaks in the line could penetrate the skin and cause
tissue damage including gangrene. If oil does penetrate the skin, have the injury treated immediately
by a physician knowledgeable and skilled in this procedure.
DANGER! Never leave the machine in the raised transport position –the machine could fall inadvertently and
cause injury or death to anyone who might be under the machine.
DANGER! Never run a tractor engine in a closed building without adequate ventilation. The exhaust fumes can
be hazardous to your health.
DANGER! Never work under the mower deck, framework or any raised component unless the mower has
been securely supported and blocked using suitable substantial items to prevent sudden or inadvertent
falling which could cause serious injury or even death.

8999129: v1 11/09/2018
Page 2.3 of 2.9 pages Original instructions (ENGLISH)
Website: www.spearheadmachinery.com
DANGER! Operate the mower only with a tractor equipped with an approved ‘roll over protection system
(ROPS). Always wear your seat belt. Serious injuryor even death could result from falling off the
tractor –particularly during a turnover when the operator could be pinned under the ROPS or the
tractor.
DANGER! The rotating parts of this machine have been designed and tested for rugged use. However, they
could fail upon impact with heavy solid objects such as steel guardrails and concrete abutments. Such
impact could cause the broken objects to be thrown outward at very high velocities. To reduce the
possibility of property damage, serious injuries, or even death, never allow the cutting blades to
contact such objects.
WARNING! Before starting, checks on tractor and machine must be carried out as regards: functionality, road
safety, accident prevention rules.
WARNING! Before leaving the tractor stopped with the machine attached, proceed as follows: Disconnect the
power take off, lower the machine steadilyto the ground (with the hydraulic lift) Apply the hand brake
and, if the ground is steeply sloping, wedge the tractor. Take out the starting key. Immediatelyreplace
any safetysign, or any missing or damaged decal.
WARNING! CHECK the blades for wear and the attachment bolts for tightness every day during work (see
Maintenance section). A few moments whenever the machine is stopped (e.g. whenever removing
obstructions) will help reduce blade wear or loss.
WARNING! Do not transport unless wings are well secured in the transport position.Wings that are not well
secured can fall during transport, causing serious damage to the tractor and mower and possibly
causing the operator or passers-by to be injured or killed.
WARNING! During checks or repairs, make sure nobodycould start the machine by mistake.
WARNING! Ensure only one person operates the machine at any one time.
WARNING! Missing or damaged guards must be replaced immediately.
WARNING! Blades will continue to rotate for some time after the tractor PTO has stopped.
WARNING! Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and
other debris. Inspect the area before mowing. Foreign objects should be removed from the site to
prevent machine damage and/or bodily injury or even death. Any objects that cannot be removed
must be clearly marked and carefullyavoided by the operator. Stop mowing immediately if flails strike
a foreign object. Repair all damage and make certain the rotor shaft is still balanced before resuming
cutting operations. NOTE: Where grass and weeds are high enough to obscure debris that could be
struck by the blades, the area should be inspected, and debris removed, mowed at an intermediate
height, and re-inspected closely to remove anyremaining debris and mowed again at the desired final
height. In addition to the safety aspect of this procedure it will also reduce wear and tear on the mower
drive-train, spread cut materials better, eliminate ‘streaking’ and make the final cut more uniform.
WARNING! Never attempt to lubricate, adjust, or remove material from the machine while it is in motion or
while tractor engine is running. Make sure the tractor engine is off before working on the Implement.
WARNING! Never connect the power take off unless the tractor engine is stopped.
WARNING! When unhitching the mower select a firm level site on which to park it - lower machine to the
ground fully (fit and adjust the hitch support prop on high hitch machines) and ‘chock’ the wheels.
Remember to disconnect hydraulics, lighting plug and PTO shaft (use the PTO support) before driving
the tractor away. Stow hoses and electrical cable neatly off the ground to avoid moisture or dirt
contamination.

8999129: v1 11/09/2018
Page 2.4 of 2.9 pages Original instructions (ENGLISH)
Website: www.spearheadmachinery.com
WARNING! For machines fitted with hitch adjustment mechanisms, never un-couple the machine without using
the hitch support jack. The hitch is veryheavy. Attempting to lift the hitch without using the jack could
cause strains. Allowing the hitch to fall suddenly and unexpectedly could result in crushing injury. Use
the support jack for lifting the mower only. Overloading the jack can cause failure with possible serious
bodily injury or even death.
WARNING! Periodically inspect all moving parts for wear and replace when necessary with authorised service
parts. Look for loose fasteners, worn or broken parts, and leaky or loose fittings. Make sure all pins
have cotter pins and washers. Serious injury may occur from not maintaining this machine in good
working order.
WARNING! Where hydraulic rams are fitted, release hydraulic pressure from the rams before attempting
maintenance. Lower the machine to the ground and lower any wings or securely block them up,
disengage the PTO and turn off the engine.

2.3 Stopping in an emergency
In an emergency bringing the blades to a stop requires familiaritywith the controls fitted to the tractor.
To stop the blades in an emergency, use the tractor ‘ENGINE STOP’ control. NOTE: The use of the tractor ‘ENGINE
STOP’ control must only be done in an emergency. Its use to stop the machine can cause damage. After an
emergencystop of the machine; ensure that the PTO is disengaged before restarting the tractor.
2.4 Dangers due to overhead power lines
There are significant dangers involved when working in the vicinity of Overhead Power Lines (OHPL’s);
DANGER: All operators must read the following information and be aware of the risks and dangers involved
when working in the vicinity of Overhead Power Lines (OHPL’s).
WARNING! Fatal electrocution can occur without contacting a power line. Due to the high electrical potential
between the conductors and the ground a flash over can occur from the power line to anyconducting
medium within range. Steel mowers are ideal conductors.
Wherever possible the safest option is always to avoid working in areas close to OHPL’s. Where unavoidable, all
operators must perform a risk assessment and implement a safe procedure and system of work, see section 2.4.1
below.
All operators should perform a risk assessment before operating any arm mower within 10m horizontal distance of
any OHPL’s. If you are unsure do not work in the area. Never put yourself or others at risk.
2.4.1 Risk assessment
Before starting to work near OHPL’s you should always assess the risks. The following points should be
observed;
Know the risks of contacting OHPLs and the risk of flashover.
Always find out the maximum reach height for your machine mounted on its tractor, see ‘Machine general
specification in chapter 1 for guidance.
Always find out the location and route of all Power Lines within the work area.
Always find out the operating voltage of all Power Lines within the work area.
Always contact the local Distribution Network Operator (DNO) who will be able to advise you on the
operating voltage, exclusion zones, the minimum safe working distance and any additional precautions
required.
Never attempt to operate the machine within an exclusion zone.
Always work with extreme caution and plan your work ahead to avoid high risk areas.
If doubt exists do not work in the area –never risk the safety of yourself or others
Further information and leaflets on this and other agricultural safety subjects are available on the ‘Health &
Safety Executive’ website at the following address: www.hse.gov.uk/pubns/agindex.htm
2.4.2 Emergency Action for Accidents Involving Electricity
Never touch an overhead line - even if it has been brought down bymachineryor has fallen. Never assume
lines are dead.
When a machine is in contact with an overhead line, electrocution is possible if anyone touches both the
machine and the ground. Stay in the machine and lower anyraised parts in contact or drive the machine out
of the lines if you can.
If you need to get out to summon help or because of fire, jump out as far as you can without touching any
wires or the machine keep upright and away.
Get the electricitycompany to disconnect the supply. Even if the line appears dead, do not touch it -
automatic switching may reconnect.

2.5 Noise
The equivalent daily personal noise exposure from this machine, measured at the operator's ear, is within the range of
80-85dB when used in conditions where the load fluctuates between zero and maximum. This applies when the
machine is attached to a tractor fitted with a quiet cab and used in accordance with the operating instructions in a
generallyopen environment. At equivalent daily noise exposure levels of between 85 and 90dB, suitable ear protectors
are recommended.

2.6 Personal Protective Equipment
When working in an unsealed cab or where windows and apertures are open to the environment, operators are
advised to wear suitable ear protectors.
When handling cutting surfaces or hydraulic equipment, operators are advised to wear suitable gloves.
When clearing blockages, clearing wire, or working with pressurised hydraulic components, operators are advised to
wear suitable eye protection.
When working at the work site, but off the tractor unit, operators are advised to wear a ‘high-viz’ garment.
2.7 Guards
DANGER! For safe operation it is essential that that all guards must be kept in position on the machine
whenever the machine is running. Spearhead Machinery disclaim all responsibility for any damage or
injury arising as a result of guards being removed, or of guards other than of Spearhead manufacture
having been fitted, or of operation of the machine other than in accordance with these instructions.
WARNING! Inspect guards twice daily or immediately damage is suspected. Always replace guards that have
damage or wear which could impair their performance
WARNING! Ensure that chains/blades and all fixings are genuine components supplied bythe manufacturer
specificallyfor the machine and are securelyattached with no parts missing or damaged.
WARNING! Ensure chain wear does not exceed the following limits;
For 10mm chains all links must have a minimum thickness of 8mm.
For 13mm chains all links must have a minimum thickness of 10mm.
Ensure all chains are the same length to maintain balance of the cutting unit.
2.8 Tractor stability
Due to the design of mowers and the work theyundertake, it is essential to ensure that the tractor is stable during work
and transport in order to eliminate anyrisk of loss of directional control, imbalance or overturning.
Before driving in transport, check that the front wheels of the tractor are both on the ground. It is advisable to have a
helper to check this. Check that the tyre shows evidence of bearing load. This is especially important to ensure
forward directional control at speed on an undulating terrain.
If the front tyres lift, add ballast weights to the front of the tractor. If ballast weights have been added to the tractor,
check that the plated tractor axle loads have not been exceeded.
DANGER! Keep your forward speed to a level appropriate to the operating conditions. High-speed
manoeuvres are verydangerous, particularly on uneven ground where there is risk of overturning.
DANGER! When the wings (if fitted) are folded for transport, the centre of gravity is raised, and the possibility of
overturn is increased. Turn slowly and with extra care on hillsides. Overturning the mower could
cause the mower to overturn the tractor and vice versa. Never fold wings on a hillside, the mower may
overturn.
DANGER! Be particularly careful in transport. Turn curves or go up hills only at a low speed and at a gradual
steering angle. Ensure that at least 20% of the tractor’s weight is on the front wheels to maintain safe
steering. Slow down on rough or uneven surfaces.
DANGER! Operate the mower only with a tractor equipped with an approved ‘roll over protection system
(ROPS). Always wear your seat belt. Serious injuryor even death could result from falling off the
tractor –particularly during a turnover when the operator could be pinned under the ROPS or the
tractor.
