OPERATING SPEEDS

PTO Operating Speed
The correct PTO speeds for operation of machines is as follows:
Engaging Drive
 Ensure the rotor control lever/switch is in the 'stop' position before engaging the PTO.
 Allow the oil to circulate for a minute or so before operating the armhead controls.
 Move the flail head into a safe working position just clear of the material to be cut.
 Increase engine speed to a high idle and start the rotor – after initial 'surging' the rotor will
run at an even speed.
 Carefully lower the flail head into the work area and begin work.
Tractor Forward Speed
The material being cut will determine the tractor
forward speed. Forward speed can be as fast as that
which allows the flail head sufficient time to cut the
vegetation both efficiently and neatly.
If forward speed is too fast this be indicated by over
frequent operation of the breakaway system, a fall-
off in tractor revs and a poor untidy finish to the work
leaving ragged uncut tufts and poorly mulched
cuttings.
'Running In' a New Machine
For the first day's work with a new machine it is
recommended that
restricted to 3 km/hr (2 mph) maximum. This will
allow machine components 'bed in' and allow the
operator to become familiar with the controls and
their response under working conditions whilst
operating at a relatively slow speed. If possible,
select a first day's work that affords mainly light to
average cutting with occasional heavy duty work –
during this period check the tightness of nuts and
bolts every hour, retightening as and when required.
