Vehicle / Tractor Preparation
We recommend vehicles are fitted with cabs
using ‘safety glass’ windows and protective
guarding when used with our machines.
Fit Operator Guard (See drawing) using
the hooks provided. Shape the mesh to cover
all vulnerable areas. The driver must be
looking through mesh and/or polycarbonate
glazing when viewing the working tool in any
working position - unless the vehicle/ cab
manufacturer can demonstrate that the penetration resistance is equivalent to, or higher than,
that provided by mesh/polycarbonate glazing. If the tractor has a roll bar only, a frame must
be made to carry both mesh and polycarbonate glazing. The operator should also use
personal protective equipment to reduce the risk of serious injury such as; eye protection
(mesh visor to EN1731 or safety glasses to EN166), hearing protection to EN352, safety
helmet to EN297, gloves and high visibility clothing.
Vehicle Ballast
It is imperative when attaching ‘third-party’ equipment to a vehicle that the
maximum possible stability of the machine and vehicle combination is achieved – this can be
accomplished by the utilisation of ‘ballast’ in order to counter-balance the additional
equipment added.
Front weights
May be required for rear mounted machines to place 15% of total outfit
weight on the front axle for stable transport on the road and to reduce ‘crabbing’ due to the
drag of the cutting unit when working on the ground.
Rear weights
May be required to maintain a reasonable amount of rear axle load on the
opposite wheel from the arms when in work; for normal off-ground work i.e. hedge cutting this
should be 20% of rear axle weight or more for adequate control, and for ground work i.e.
verge mowing with experienced operators, this can be reduced to 10%.
All factors must be addressed in order to match the type and nature of the equipment added
to the circumstances under which it will be used – in the instance of Power Arm hedgecutters
it must be remembered that the machines centre of gravity during work will be constantly
moving and will differ from that during transport mode, therefore balance becomes critical.

HXF 2800 / 2802 AHS

Factors that affect stability
Centre of gravity of the tractor/machine combination.
Geometric conditions, e.g. position of the cutting head and ballast.
Weight, track width and wheelbase of the tractor.
Acceleration, braking, turning and the relative position of the cutting head during
these operations.
Ground conditions, e.g. slope, grip, load capability of the soil/surface.
Rigidity of implement mounting.
Suggestions to increase stability
Increasing rear wheel track; a vehicle with a wider wheel track is more stable.
Ballasting the wheel; it is preferable to use external weights but liquid can be
added to around 75% of the tyre volume – water with anti-freeze or the heavier
Calcium Chloride alternative can be used.
Addition of weights – care should be taken in selecting the location of the
weights to ensure they are added to a position that offers the greatest
advantage.
Front axle locking (check with tractor manufacturer).
NOTE: The advice above is offered as a guide for stability only and is not a guide to vehicle strength. It
is recommended that you consult your vehicle manufacturer or local dealer to obtain specific advice on
this subject, additionally advice should be sought from a tyre specialist with regard to tyre pressures
and ratings suitable for the type and nature of the machine you intend to fit.
Attachment of the machine must be performed in a safe location on a firm
level site.
Care should be adopted at all times when handling or manoeuvring the machine during the
attachment procedure; ensure all persons remain clear of the cutting blades which possess
the potential to cause injury even when stationary. For reasons of safety the blade guard
should be fitted to machine at all times and only removed for machine operation.

attempting to use it in any public place. We advise therefore that the prospective operator make use of relevant
training courses available such as those run by the Agricultural Training Board, Agricultural Colleges, Dealers
and GreenTec.
Working in Public Places
When working in public places such as roadsides, consideration should be paid to others in the vicinity. Stop the
machine immediately when pedestrians, cyclists and horse riders etc. pass. Restart only when they are at a
distance that causes no risk to their safety.
Warning Signs
It is advisable that any working area be covered by suitable warning signs and statutory in public places. Signs
should be highly visible and well placed in order to give clear advanced warning of the hazard. Contact the
Department of Transport or your Local Highways Authority to obtain detailed information on this subject. The
latter should be contacted prior to working on the public highway advising them of the time and location of the
intended work asking what is required by way of signs and procedure. – ‘Non-authorised placement of road
signs may create offences under the Highways Act’.
Suggested Warning Signs Required
‘Road works ahead’ warning sign with a supplementary ‘Hedge cutting’ plate. ‘For 1 km’ or appropriate
shorter distance may be added to the plate.‘Road narrows’ warning signs with supplementary ‘Single file
traffic’ plate. White on blue ‘Keep left’ (*) arrow sign on rear of machine.
* Note – this applies to EU Market machines where traffic passes to the left of a machine working in the
same direction as the traffic flow. The direction, use and colour of the arrow sign will depend on the
country of use and the Local Highway Authorities regulations in the locality.
Use of Warning Signs
▲ On two-way roads one set of signs is needed facing traffic in each direction.
▲ Work should be within 1 km of the signs.
▲ Work only when visibility is good and at times of low risk e.g.: NOT during ‘rush-hour’.
▲ Vehicles should have an amber-flashing beacon.
▲ Ideally, vehicles should be conspicuously coloured.
▲ Debris should be removed from the road and path as soon as practicable, and at regular inter-
vals, wearing high visibility clothing and before removing the hazard warning signs.
▲ Collect all road signs promptly when the job is completed.
