Selecting and using Equipment for All Terrain Vehicles (ATVs)
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
1. The safe ratio between the trailed laden maximum weight and unloaded weight of the ATV
must be assessed for each operation.
2. Always take note of information given in the manufacture′s handbook when making this
assessment.
3. As a guide research shows that on level ground, 4 x unloaded weight of the ATV for braked
trailed equipment and 2 x unloaded weight of the ATV for un-braked trailed equipment are the
appropriate maximum ratios.
Note: For work on slopes or uneven ground the ratio will need to be reduced.
Hitching and Loads
Stability is also improved if:
1. Some weight is transferred from the trailer onto the ATV draw-bar;
2. 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;
3. The load is positioned as near to the center of the trailer as possible.
Tyres and Wheels
1. Check tyre pressures regularly with a pressure gauge capable of reading low pressures
accurately;
2. Check tyres regularly for damage and wear;
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.
Mounted Equipment
ATVs using mounted equipment are safer if the equipment has:

4
a low center of gravity. This improves stability.
a gross weight within the limits approved by ATV manufacturer.
no dangerous projections to injure the operator or bystanders;
no forward projections which stop head protection being worn;
controls which are easy to work and which do not create a hazard to the operator;
Instructions for Mounted and Trailed Equipment
Take note of the manufacturer′s instructions on:
Operating on slopes;
Where to place loads so as to give fore/aft and lateral stability;
The risks of using equipment with negative drawbar nose weight, i.e. loss of traction;
The maximum operating speed;
The effect that equipment carried on front and/or rear racks will take on longitudinal and
lateral stability;
Securing loads;
The use of ballast, if any, to improve stability;
The need to select and use safe routes.
Using an ATV
Read the manufacturer’s instruction book and take note of the safety advice given;
Choose an ATV with enough power for the work you want it to do. four-wheel drive will give
better traction and mobility and may provide a margin of safety;
Choose a safe route;
Be aware that increased speed greatly increases the risk of instability and risk of and
overturn;
Training
Train everyone who has to use an ATV whether with mounted or trailed equipment or as a solo
machine. The training should emphasize the factors affecting stability, the need for care and
concentration, and how to recognize the conditions which may affect the safety of operation, it is
important for trainees to familiarize themselves with the handing and control of the machine on level
open ground before tackling rough hill terrain.
Suitable training courses are run by bodies such as ATB Land base and the forestry Authority.
Helmets
Wear head protection which protects the head and neck. Helmets are suitable. Some users find
open faced helmets more suitable than full face helmets.
1. DO NOT－Operate the mower without all the correct guards fitted.
2. DO NOT－Alter engine settings unless stated by Engine manufacturer.
3. DO NOT－Touch any moving or rotating parts, during working conditions

The ATV FLAIL MOWER is designed to give safe and dependable service if operated according to
instructions and intended use.
Read and understand this manual before operating the mower, as failure to do so could result in
personal injury or equipment damage.
When used with and ATV or compact tractor, ear defenders should be worn. Under normal
working conditions a noise level of 83 decibels would be usual, in the case protection is advised.
1. Make sure that all nuts, bolts and fittings are securely fixed, and that all packaging materials
e.g. wire bands, tape etc. have been removed. (Remove tape from the front stone deflectors
from the underside of the body)
2. Check there is oil in the engine and petrol in the tank.
3. Check Tyre pressures.
The above decals should be located on your ATV –Flail Mower. If any of the above decals are not
located on your ATV or are damaged in damaged in any way contact for some replacement decals before
use.

OPERATING INSTRUCTIONS AND ADJUSTMENTS
5.1 INITIAL CHECK

8
The drawbar attachment height of the towing vehicle can vary. To accommodate adjustment, a screw
link is located beneath the drawbar. This should be lengthened or shortened so that the cutting deck
is horizontal to level ground. (This ensures a better cutting efficiency)
TO ADJUST
1. Unlock the locking nut (A)
2. Lengthen the link to lower the front of the deck or shorten to raise the deck.
3. Once the deck is level, re-tighten locking nut (A).
A
QUICK OFFSET DRAWBAR Unlock the nut and screw slide the drawbar to the desired position
and release the screw into the securing hole then lock the nut, as shown.
Hole Settings
The main cutting height adjustment is achieved by using the screw jack, to raise or lower the cutting
deck as necessary.
5.2 DRAWBAR ADJUSTMENT
5.3 MOWER CUTTING HEIGHT

9
CUTTING HEIGHT ADJUSTMENT:
Turn the handle to raise or lower as necessary.
READ AND UNDERSTAND THE ENGINE OPERATORS
MANUAL BEFORE USE
Observe all safety precautions; keep hands and feet away from rotor and other moving
parts. Keep spectators at a safe distance.
1. Make sure there is a gap between the blades and the ground / crop
2. Select an area clear of loose debris that could be picked up.
3. Set the engine choke, and suitable idling speed with the throttle.
4. Place one foot on top of the deck body to give a firm and balanced position. Pull the starter
cord firmly, allowing the cord to return to return to the housing slowly (one or two strong pulls
should start the engine).
5. After a few seconds warming up at idling speed, move the throttle to the factory pre-set
working position to give a normal/working engine R.P.M of 3600 max.
ELECTRIC START
Push button electric start engine options can be supplied if required. Simply hitch up the mower,
connect the electrical supply plug to the ATV socket and turn the ignition key to start the mover.
Observing all the precautions mentioned above in ‘Starting the mower’.
REMOTE THROTTLE CONTROL
When a remote throttle control option is fitted, normally to the rear carrier frame of an ATV or other
suitable site on the towing vehicle, it gives the operator the facility of controlling the mower engine
5.4 STARTING THE ENGINE
NOTE: If the throttle is altered to increase the engine R.P.M beyond the recommended level, the
guarantee may become invalid. In addition to this, cutting efficiency will be reduced, fuel consumption will
increase and excessive vibration could be caused, resulting in a potential danger to personnel and damage to
components.

10
from the operating position. The facility is most beneficial when moving from one cutting site to
another close to it, by reducing the engine revs to allow the mower flails to come to rest, no harm will
be caused to the mower or ground surface during transport, often over rough or difficult terrain when
stones and loose objects may be encountered.
The amount of grass or weeds to be cut dictates the forward speed; slow forward speeds give better
results in most cases. Ensure you follow the procedure below.
NORMAL FORWARD SPEED (1 kph－very heavy use－10 kph －very light use)
Start off in the slowest speed possible, ensure the mower is working efficiently with the engine set at
maximum RPM and not labouring. (If this is not possible due to very heavy cutting conditions, raise
cutting height of blades and be prepared to go over twice with machine set lower on 2nd pass, leave
at least 24 hours in between 1st and 2nd cut to allow grass to dry out)
Increase forward speed until the RPM of the engine starts to slow down (This is working the engine
too hard for conditions) –slow down, let the engine regain full RPM and go through the same process
but stop short of speed which made engine labour previously. It is important always to listen to note
of engine to ensure engine and mower are working efficiently, slow down or stop once engine starts
to labour.
FAILURE TO DO THIS WILL RESULT IN CLUTCH SLIP AND
ULTIMATELY SEVERE DAMAGE TO THE CLUTCH AND DRIVE BELTS.
When stopping the mower after a period of heavy use. Run the machine at half working speed in a
stationary position, for at least 4 minutes, to allow the drive belts to cool down.
1. Show caution to hot parts e.g. engine exhaust, belts etc. after engine is switched off.
2. Ensure the mower drawbar has been adjusted to allow the mower to run directly behind the
towing vehicle and is not in an offset position
3. When the mower has cooled down (Min 1hr after last used) Ensure all grass has been
removed from engine cooling fins, drive belt area, and rotors before operating again.
When the mower is being moved from one site to another it is advisable to raise the deck to
the highest position (Transport position, See section 5.3 “Mower cutting height”)
The engine must be stopped and the blades at a standstill before adjusting to the transport
position.
Remove any crop debris from the deck before leaving the field.
5.6 STOPPING THE MOWER
When moving from normal working conditions to heavier cutting, it may be evident that
the engine dies down and loses revs. SLOW DOWN IMMEDIATELY to allow the engine revs to
build up again to normal working speed. Follow the procedure detailed above in “Normal Forward
Speed”. Expected forward speed will be much lower in heavy conditions.
FAILURE TO DO THIS WILL RESULT IN CLUTCH SLILP AND
ULTIMATELY
SEVERE DAMAGE TO THE CLUTCH AND DRIVE BELTS.
5.5 FORWARD SPEED
5.7 TRANSPORT POSITION

11
Never move from one site to another with the engine running.
Please note the ATV –Flail Mower is not road legal, and should not be used on public
roadways
The main purpose of the anti-scalping roller is to prevent damage. If a wheel drops into a hole, or
there is uneven ground between the wheels, the roller takes the weight of the mower, avoiding the
flails scalping the ground; combined with the side skids the mower provides good protection to the
rotor.
The anti-scalping roller has the added advantage of-enabling kerb side grass to be cut with no
difficulty, by allowing the wheel to hang over the kerb edge.
The factor pre-set position of the anti-scalping roller and side skids are suitable for most situations.
However, if the mover is used in rough conditions or regularly in heavy crops, the roller and side skids
should be lowered, to increase the clearance between the flail and the ground when the roller comes
into use.
In circumstances where the mower is being used as a “Finishing Mower” and a striped appearance is
desired, the roller can be set down using the various hole positions to give the required cutting height,
then the wheels can be lifted clear of the ground.

6.3 VISUAL CHECK
Make a visual check around the mower, check for missing / loose parts or damaged / worn
components. All-faults must be either repaired or replaced.
6.4 TYRE PRESSURES
6.5 ROTOR BEARING INSPECTION
Rotate rotor shaft by hand and feel for any roughness in the bearings. Also try to pull the shaft from
side to side to see if any movement is found. If symptoms persist strip down the rotor-housing unit
and inspect bearings.
6.6 WHEEL BEARING INSPECTION
Jack one side of the mower body up, so the wheel is just off the ground. Rotate the wheel by hand,
and check the wheel alignment. To check the bearing, try to move the wheel from left to right and feel
for any play in the bearings (A), ensure the wheel-locating bolt is tight before you start and follow any
jacking procedures. If any play is found remove the wheel and inspect bearings. Replace any faulty
bearings.
6.7 OIL 50mm COUPLING/BUSH WEAR
Check coupling for signs of damage or wear, swivel the coupling 36. degrees and check that the
bushes are not too worn. Replace any worn or damaged parts.
6.8 GENERAL INSPECTION
Check the mower to ensure all fasteners are tight and all safety guards / chains are intact and fitted
securely. Check all safety-warning decals, Replace any defective guards or damaged decals.

6.9 ROTOR FLAIL MAINTENANCE
The ATV Mow range has Forged Hammers designed to last a long time. However, when breaking or
losing hammer, it is important to replace it immediately. Failure to do this can cause serious
unbalancing problems. (Always use spare parts)
At the time of replacement, the opposite hammer on the rotor should be checked for wear. If it is
partially or well-worn then if should be changed to maintain an accurate weight balance.
Replacing the hammers follows this simple procedure:
(A) Ensure mower engine has stopped and the knives have stopped rotating. Switch of the fuel
tap and let the machine cool down for 5 minutes. Remove the spark plug to ensure the engine
cannot be started.
(B) Raise the mower to its max cutting height.
(C) Carefully raise the drawbar to an incline position, so that height adjuster bar at the rear of
the mower takes the weight. NB; Do not attempt this with the wheels behind version; raise the
front jack to its max height.
(D) Slacken and take out the shackle bolt.
(E) Replace or turn around blades (Note the direction of rotation)
(F) Replace shackle bolt securely, but still allowing the shackle to swing on the fixing bush.
NOTE:
ATV Mow Flails have a rear gate that can make changing hammers easier.
For repairs beyond the minor adjustments listed above, contact your local dealer or
contact.
