Even though the pressure is locked in the circuit, this system does remain active in
that the legs can be raised up out of work. The tractor hydraulics should be
returned to float to relieve any back pressure before commencing work at the new
pressure
Note: It is advised that on a machine fitted with auto reset legs the double acting
feature is used in road transport to retract the legs and reduce the overall width
of the machine on the road and move the sharp points to well within the

Discs
Disc are usual set in one of three ways: a tilt mechanism, hinge racks operated
by hydraulic cylinders, and by setting packer depth which automatically sets the
disc depth.
Tilt mechanisms are most commonly used on our Leading
Disc. Simply remove the pin/bolt, tilt to desired angle and
reinsert pin/bolt.
Hinged disc arrangements operate
simply from a sequence of hydraulic
cylinders. To lower or raise, simply
adjust the hydraulic pressure.
