Exterior rear hydraulic arms controls
Outer hydraulic circuit
Exterior rear hydraulic arms controls are located on the
rear right wing. They make it easier for the operator to
conncet tools by controlling the movements of the lower
drawbars of the three-point hitch from the outside. They
only serve for connceting and disconnecting the tools.
