Warnings
Never attempt to operate the machine when travelling backwards, the break
back will not function and any damage caused will not be considered warranty.
The break back feature does not excuse the machine operator of their need to
be aware of obstacles and to avoid hazards. It is your responsibility to
maintain a long reliable working life.

A ‘swing link breakback’ system is built into the machine; this offers a degree of protection
to machine components if an obstruction is encountered during normal work.
The break back link will operate if the machine is overloaded i.e. a dense patch of
vegetation, too high a forward speed, and when working up hill.
The tractor must be halted and flail head manoeuvred around the obstacle, the machine
then reset before continuing.
Two parking stand legs are fitted to the machine, which once the machine has been
attached to the tractor should be folded away in the ‘stow’ position.
The machine has ‘angle head flotation’ as standard –this is engaged by moving the head
rotation lever beyond the normal actuation range into a detented ‘float’ position. ‘Lift float’
is available as an option on the machine.
All machines have a relief valve in the primary ram system, this limits the pressure which
can be generated in the drop side of the cylinder – the cutting head cannot therefore be
‘driven’ into the ground in any circumstances.

Tractor Specifications Tractor Specifications Tractor Specifications Tractor Specifications
Tractor size must be a minimum of 45kW (60 HP) – 3000kg
Tractors must be equipped with a power take off (PTO) shaft that must run at 450 rpm
during operation. The PTO shaft should run clockwise when viewed from the rear of the
tractor and ideally be of a 1
⅜ ” S.A.E. – 6 spline shaft type to enable a standard PTO shaft
to be connected.
The tractor should have counterbalance weights (on approved mountings) fitted if
necessary and/or ballasted wheels to ensure stability of the unit at all times.
Stability may be further increased with a wider track setting on the tractors rear wheels –
contact your local dealer or tractor agent for specific advice on this subject.
Four wheel drive tractors have extra weight inbuilt plus larger front wheels, this is an
advantage in keeping the unit stable.
