Introduction
This information sheet gives advice to users on how
to use All Terrain Vehicles (ATVs) safely with towed
and mounted equipment.
Plan the use of an ATV carefully and take particular
note of ground conditions and slopes, as these may
vary considerably, depending on the terrain, weather
conditions, ground surface and the crop under the
wheels.
Towed equipment
Choose equipment which matches your ATV.
Stability of towed equipment is affected by:
Weight ratios
The safe ratio between the trailed laden maximum
weight and unladen weight of the ATV must be
assessed for each operation.
Always take note of information given in the
manufacturer’s handbook when making this
assessment.
As a guide research shows that on level ground, 4 x
unladen weight of the ATV for braked trailed
equipment and 2 x unladen weight of the ATV for
unbraked trailed equipment are the appropriate
maximum ratios.
Note: For work on slopes or uneven ground the ratio
will need to be reduced.
Braking
Fit:
Brakes to trailed equipment. This helps prevent jack-
knifing when braking or travelling downhill;
Over-run brakes which come into action whenever
the ATV brakes are applied;

Centre of gravity
Stability of the ATV is improved if there is:
A low centre of gravity which is within the wheel
base;
A wide wheel base;
A long draw-bar;
Means for holding detachable equipment in position.
Hitching and loads
Stability is also improved if:
Some weight is transferred from the trailer onto the
ATV draw-bar;
The draw-bar has a swivel hitch and the ATV a ball
hitch having a large head to neck ratio. This makes it
easier for the draw-bar hitch to swivel and cope with
undulating ground;
The load is positioned as near to the centre of the
trailer as possible.
Tyres and wheels
Check tyre pressures regularly with a pressure
gauge capable of reading low pressures accurately;
Check tyre pressures regularly for damage and
wear;
Select equipment which has tyres and wheels that
can cope with speeds over 20 mph and occasional
higher speeds;
Use wheels with bead locks on the rims if the main
use is going to be on sloping ground. This prevents
tyre run-off on side slopes.
Maximum towed weight
Follow the advice given by manufacturers on the
maximum trailed weight. This will be found on the
equipment or in the instruction handbook.
Note: Universal road going trailers will normally have
the maximum gross weight stated on a separate
notice.
