IMPORTANT SAFETY WARNINGS
Wessex machines are guarded for your protection, but you must always observe certain
elementary precautions. Machines are potentially dangerous and should be used with the greatest
respect and ALL OPERATORS MUST read this manual and be are aware of all safety
precautions.
1. NEVER attempt any adjustment whatsoever, unless the machine is COMPLETELYat a
standstill and the P.T.O. drive and blades have stopped turning. Stop Engine and remove
Tractor Key.
2. NEVER attempt to clear any obstructions around the mower unless the machine is
COMPLETELYat a standstill and the P.T.O. drive and blades have been stopped. Stop
Engine and remove Tractor Key.

Engine and remove Tractor Key.
4. NEVER remove safety guards which are provided for your protection.
5. NEVER operate the mower with people around, keep everybody (especially children and
animals) at a safe distance, minimum 20 metres.
6. Stand well back from the machine when cutters are spinning.
7. Regularly inspect the BLADES AND FIXING BOLTS to ensure that they are in excellent
condition. Replace blades IMMEDIATELYif any signs of fracture or excess wear becomes
apparent. Serious damage, which is excluded from our warranty conditions, may result from
using your mower with an unbalanced rotor. When replacing blades, always fit new
mounting bolts and nuts to ensure that the rotor is balanced and running smoothly.

LINKING UP TO THE TRACTOR
1. Always hitch and unhitch on level ground for safety reasons.
2. When hitching up, never allow anyone to stand between the tractor and the implement.
3. Reverse the tractor up to the RMX Tri-deck and hitch up to the towing hitch. When using a
drawbar pin ensure that it is secured with a lynch pin.
.When in work the drawbar of the RMX Tri-deck should be level with the ground, to adjust simply
remove drawbar holding bolts and pivot up or down, or turn the drawbar over for extra
adjustment.
5. Stop the tractor’s engine and couple the P.T.O. Shaft to the tractor putting the wide angle joint
onto the tractor. Always hook the P.T.O. chains onto the lugs provided and shorten the chains to
suit. The P.T.O. chains must not encircle the P.T.O. guard, as this will cause premature P.T.O.
guard damage and wear. Ensure that the P.T.O. Shaft is correctly located and locked in place.
(See P.T.O. Shaft Instructions at the back of the book).
6. Connect the lighting plug into the tractor.
7. Connect the hydraulic hoses to the tractor.
8. IMPORTANT:Ensure that the bottom link arms of the tractor do not come into contact the the
P.T.O. Shaft when turning. We recommend that you remove or raise up the tractor link arms by
adjustment of the arms.
USING THE RMX TRI-DECK
1. Having hitched up to the tractor you are now ready to lower the mowing decks to the ground.
2. Operate the hydraulic functions to take the weight off the safety catches of the side and rear
deck carriers.
3. Release the safety catches by activating the catch lever beside the drawbar at the front of the
machine, then slowly activate the hydraulics to lower the decks to the ground.
4. Important Ensure that all bystanders are at a safe distance from the machine before lowering
the decks.
5. It is important that the hydraulic spools on the tractor are in the float detent position so that the
machine will float and follow the ground contours. If the tractor has no float detent the spool
can be locked in the down (dump position) by means of an elastic cord restraint fixed to the
spool lever. If you are unsure of the float operation for the tractor’s hydraulics consult your
Wessex Dealer for advice.
6. NEVER USE THE MOWER IN P.T.O. SPEEDS IN EXCESS OF 540 RPM.
