Vehicle / Tractor Preparation - McConnel MAGNUM MULCHA 225 Operator's Manual

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 (Part No. 7313324)
using the hooks provided. Shape the
mesh to cover all vulnerable areas.
Remember the driver must be looking
through mesh and/or
glazing when viewing the machine in all positions - 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, filter mask 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.
Where a machine works to the side of the tractor rear weights may be required to maintain
a reasonable amount of rear axle load on the opposing wheel.
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 - factors that effect stability are:
 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 unit 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.
The advice above is offered as a guide for stability only and is not a guide to vehicle strength. It is
therefore 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.
