Adjusting the Transport Levelling Control Arm
With the disc attached to the tractor, the hydraulics
connected and with the transport stay removed from
the hydraulic cylinder; the disc can be adjusted to
transport level as in illustration A. The adjustment is
carried out by turning the nuts indicated in the
illustration. When the disc is raised out of the ground
in the transport position, there is pressure against
these nuts. Therefore, to make adjustment easier,
lower the disc to the ground to take pressure off the
nut. The nut can then be turned easily by hand or
wrench. To lower the front of the disc as in illustration B, turn the nuts in the direction indicated as B.
To raise the front of the disc as in illustration C, turn the nuts in the direction indicated as C. It may be
necessary to raise and lower the disk a number of times to attain the desired result. Once the disc is
level, lock the nuts together on the eyebolt shaft. This adjustment remains unchanged as long as there
is no change in the tractor hitch height.
WARNING: To avoid serious injury to self or others, do not allow anybody on or near the disc
when it is being raised or lowered. In particular, if someone other than the tractor operator is
making adjustments to the disc, the tractor should be switched off while adjustments are
being made and only restarted when that person is well clear of the disc.
Transporting the Disc
Raise the disc to its maximum height by completely extending the
hydraulic cylinder. Install the transport stay over the hydraulic
cylinder rod with the plated end against the head gland of the
cylinder. Install the retaining pin. On tractors with open centered
hydraulics, switch the tractor off and relieve the hydraulic pressure
by moving the hydraulic spool lever back and forth. With closed
center systems, carefully use the hydraulics to take the pressure
off the hydraulics and allow the weight of the disc to be taken up by
the transport stay.
To prevent the wing sections from being accidentally
unfolded during transport, turn the shut-off handle fully
clockwise after folding the wings.
