Operating Speed - McConnel PA 35 Series Operation Manual

OPERATING SPEED

WARNING: Damage to the machine may occur if the maximum PTO speed is exceeded.
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 – Flail Head Fitted
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 days 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 days 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.
First day use - check tightness of nuts & bolts hourly ►
tractor forward speed is
24
NOTE: For cutterbars 500 rpm
is a guide speed only – it
should be run only as fast as
necessary to perform
required job. Never exceed
540 rpm PTO speed.
