________4. Adjustment and Operation
Spread-A-Bale, the terrain, overhead
obstructions and the safety of other
workers and animals.
It is important that the Spread-A-Bale is
moved about the farm best positioned for
the maximum all round vision and stability
with the auxiliary hydraulic control in
neutral.

4.10 Detachment
It is important to clear the floor of the
storage area of debris or projections that
could damage the belt of the Spread-A-
Bale.
Always park with the head lowered.
Position the Spread-A-Bale flat on the
floor of the storage areas.
Depressurise the hydraulic system and
disconnect the two hydraulic lines to the
boom.
Disconnect the head locking mechanism
before detaching and driving away.
4.11 Control Adjustments
Varying the rotational speed of the rotors
and the attack angle of the blades can
influence the factory set approximate 8-
metre arc spread range. Decreasing the
speed of the rotors reduces the range of
throw.
The control valves are nominally set at the
factory and can be adjusted to suit the
characteristics of the individual Loader by
the commissioning engineer.
Before any adjustments are made the unit
should be placed on the ground in a stable
position and the power unit switched off
with the key removed.

Only two valves may need to be adjusted
for different bale characteristics:
Valve 1 – Main Flow Proportioner Valve
Turning this valve
clockwise will reduce the
flow of oil towards the
rotors and simultaneously
increase the flow of oil to
the belt. Turning this fully
clockwise will stop the
rotors and increase the
belt speed.
Turning this valve
anticlockwise will
increase the flow of oil to
the rotors and decrease
the flow to the belt.
Turning this valve fully
anticlockwise will give
you maximum of 640rpm
on the rotors and
minimum belt speed.
