EXTERIOR REAR HYDRAULIC ARMS CONTROLS
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.
Img. (A)
Before using exterior controls, move the power regulation lever (1) to its utmost
position.
Lowering hydraulic arms img. (B):
Move lever (3) in the direction shown by the arrows (moving the lever is restricted
with a link). By repeating this procedure, hydraulic arms are lowered in small steps.
Raising hydraulic arms img. (C):
Move lever (3) in the direction shown by the arrows (moving the lever is restricted
with a link). By repeating this procedure, hydraulic arms are raised in small steps.
If the lifting device controlled by exterior controls is loaded, movement of the
lower drawbars within one step (on the exterior controls) is longer than if
unloaded.
OUTER HYDRAULIC CIRCUIT
It supplies pressure oil for hydraulic
devices on outer drives of hydraulics
ended with couplers. Coupler sockets
with 12.5 mm bore are in accordance
with the international recommendation of
ISO.
