COMMISSIONING THE MOWER
Commissioning the Mower continued
Operate the Lift/Lower control switches in turn to
lift the left hand wing cutterhead, the centre three
cutterheads and the right hand wing cutterhead.
Carry out this exercise with care and observe the
movement of the cutterheads to ensure that they
are not impeded by poor routing of the hydraulic
hoses.
WARNING: PREVENT ACCIDENTS - The
centre cutterhead will stop rotating when the
transport height is reached. All other cutting
cylinders should stop rotating when the outer
part of the outer part of the cutter head reaches
a height of 300-400mm above the ground. If the
cutting cylinders continue to rotate above this
height limit, it is essential to adjust the position
of each diverter valve to achieve this require-
ment.
Check and repair any hydraulic leaks.
WARNING: PREVENT ACCIDENTS - Lower
all cutterheads to the ground, disengage the
P.T.O. drive, stop the tractor engine, apply the
tractor parking brake and remove the ignition
key before making any adjustments.
After making final adjustments, operate each cir-
cuit in turn to eliminate any air from the hydraulic
system and closely observe the movement of the
hydraulic hoses. Ensure that the motor hoses move
freely without impeding the movement of the cut-
terheads through the full range of travel. Observe
the hoses at each cutterhead to ensure that their
ability to follow ground contours is not impeded.
Ensure that hoses do not braid adjacent hoses or
other parts of the machine.
With all cutterheads on the ground and the three
individual Lift/Lower switches in the 'Down/Cut'
position, operate the override control switch to the
'Neutral' position. All the cutting cylinders should
stop rotating instantly. Operate the override control
switch to the 'Raise' position until they are fully
lifted.
Operate the override control switch to the 'Down/
Cut' position to lower all cutterheads simultaneous-
ly. The cutting cylinders will start to rotate when
they are 300 - 400mm above the ground.
