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. RC 162 has been tested on the following Arm systems:
Spearhead Twiga MID, PRO & Flex with tractors from 4400 kg, wheelbase of 250 cm
and a track width of 200 cm measured from / to the outer edge of the tire till tractors of
5500 kg , wheelbase of 280 cm and a track width of 250 cm measured from / to the
outer edge of the tire. Because there are different types of tractor structures and
differences in weight distribution you must view this as a "guideline". Is it possible, then
choose wide tires as possible to increase the stability of the vehicle.
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
hedge cutters 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.

12 Hedge Cutter RC 162
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.

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.

BEFORE STARTING WORK:
Description of the RC 162 Hedge Cutter:
Hydraulic driven hedge cutter.
The tool is used for hedges and smaller branches and bushes, that have a maximum
diameter of 40 mm without fraying the branches. The machine consists of a self-
supporting shield with 3 shafts for mounting rotors with 6 tempered knives. Each shaft
is driven by ridged belts and the overall working is through the hydraulic driven vehicle.
The branch raiser is situated beneath the lower rotor. The hedge cutter is supplied with
an adapter for mounting on various vehicles. The belt drive is fully covered by a safety
steel cover. Gaining access to the belt drive for maintenance purposes requires
loosening 2 bolts.
Setting up for work:
•Wear safety glasses and work gloves.
•Remove transport safeguard if fitted and turn the armsystem into workposition.
•Start the tool at low oil flow (low rpm). Let the tool warm up for a few minutes.
•Adjust the RC 162 horizontal or vertical for hedge cutting and raise into work
position.
•Adjust the rotor rotations to the recommended speed and drive with a safe speed
that is adjusted to the terrain and other possible obstacles.
Tool start:
•Choose low engine rpm.
•Make sure that the surrounding is secured.
•Warm start –Start the tool.
•Cold start –never start the tool at maximum rpm. Let the tool run without too
much strain for approx.. 15 minutes to heat up the oil.
•Slowly increase rpm until the correct oil amount is reached.
•Never attempt to restart a strained/wedged in tool. Stop the tool and the vehicle
engine. Remove the ignition key and engage the handbreak. Only then it is safe
to remove the wedged in material. Always wear safety glasses and work gloves.
Tool stop:
•Reduce engine rpm to fast idling and stop the tool.
•Never increase or reduce the oil amount too fast. This will damage the hydraulic
system on a long-term basis.
•When you are finished working, stop the engine, remove the ignition key and
engage the handbreak. Always wear safety glasses and work gloves. Refit
safeguard. Beware of sharp cutting parts!
•Always show consideration for other road users during transportation.
Power lines:
Always pay close attention to overhead lines. Between
power poles there is always a risk of hitting overhead
lines. When in doubt please contact your local power
station for advice concerning safety distance.
