VEHICLE/TRACTOR PREPARATION
We recommend vehicles are fitted with cabs
using ‘safety glass’ windows and protective
guarding when used with our machines. Fit an
Operator Guard
such as Spearheads’ available
guard kit (part number OPT0603) and using the
hooks provided fit it to the vehicle. Shape the
mesh to cover all vulnerable areas. The driver
must be looking through mesh and/or
polycarbonate glazing when viewing the
complete working machine 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 protection equipment
(PPE) 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
EN297, gloves and high visibility clothing.
Vehicle Ballast
It is imperative when attaching ‘third-party’ equipment to a vehicle that the maximum
possible stability can be accomplished by the utilisation of ‘ballast’ in order to counter-
balance the additional equipment added. RC Rotary Hedge Cutters have been tested
on the following reach arm systems: Spearhead Twiga MID, PRO & FLEX with tractors
from 4400kg, wheelbase of 250 cm and a track width of 200 cm measured from/to the
outer edge of the tyre till tractors of 5500kg, wheelbase of 280cm and a track width of
250cm measured from/to the outer edge of the tyre. 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 tyres 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 reach 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.
