FITTING OPERATOR CONTROL UNITS
Fitment of the operator controls in the tractor cab will vary depending on the particular
model or specification of machine – the information below lists the differing methods of
fitment for the various types of controls available.
NOTE: Electric control units work within the range of 12v-16v DC and will require a
minimum power supply of 12v DC.
Cable Controls
Cable control units are provided with, and attached to, a mounting bracket – the bracket
should be securely fixed to the internal mud wing or cab cladding in a suitable convenient
location that offers ease of use without interfering with normal tractor operation.
In deciding the final position of the control unit bear in mind the location of the cable run –
make sure the minimum acceptable cable bend radii of 8” (200mm) is not exceeded.
Ensure during fitting that no structural member of the tractor cab or roll bar is drilled or
damaged.
The cable rotor control valve lever on cable controlled machines will be assembled as a
component part of the main bank of controls and therefore shares the same mounting
bracket.
On electric machines with cable operated rotor control valve the lever will be supplied as a
‘standalone’ unit with its own individual mounting bracket – this should be fitted in the
same manner as above adopting the same precautions pertaining to attachment and cable
runs.
Electric Controls
Depending on the particular type of control, electric units are supplied either with a
mounting bracket or a mounting pillar which should be bolted to the internal mud wing or
cab cladding in a suitable convenient location that offers ease of use without interfering
with normal tractor operation. Mounting pillars can be bent or twisted to achieve a
comfortable working position. Ensure during fitting that no structural member of the tractor
cab or roll bar is drilled or damaged.
The power supply cable should be connected directly to the tractors battery - do not use
cigarette lighter type connections as these prove to be sporadic and unreliable for control
applications. Control units are 12 volt DC operated; the brown lead is positive (+) and the
blue lead is negative (-).
RUNNING UP PROCEDURE
Ensure that the rotor control valve is in "STOP" position, start tractor, engage PTO allow
the oil to circulate through the return line filter for about 5 minutes without operation of the
armhead control lever.
Operate the armhead levers through their complete range ensuring that all movements are
functioning correctly.
Place the flail head at a safe attitude and move the rotor control to "START" position. After
initial fluctuation the rotor should settle to a steady speed. Increase PTO speed to
approximately 360 rpm. and run for a further five minutes before disengaging and stopping
tractor.
Check the hose runs and observe that they are free from any pinching, chaffing, straining
or kinks. Re-check the oil level in the tank-and top up as necessary.
