SECTION 3 – OPERATION
6. (Continued) WING LIFT CYLINDERS AT REST IN TRANSPORT POSITION.
7. Lower wings with caution. Do not raise or lower the wings when moving. Operate tractor hydrau-
lics from operator station only. Do not allow any one near Coulter-Chisel when wings are
raised or lowered.
IMPORTANT
A one-way restrictor is installed in wing lowering hydraulic circuit. This has been done to
reduce chance of wing free fall. Do not remove this restrictor.
