The Quickhitch red locking-pins are operated hydraulically
and are used to lock an attachment onto the Quickhitch
system.
When the power diverter lever/Quickhitch isolator switch is
operated at the same time as the auxiliary buttons/lever,
hydraulic pressure is diverted to the Quickhitch red
locking-pins.
– When the red locking-pins are fully out, they are
disengaged.
– When the red locking-pins are partially out, they are
part-engaged.
– When the red locking-pins are fully in, they are fully-
engaged.
