ADC 2220/1150 Older Style Hoses with Color Ties
Refer to Figure 14
To distinguish hoses on the same hydraulic circuit, refer
to plastic hose label. The hose under an
extended-cylinder symbol feeds a cylinder base end. The
hose under a retracted-cylinder symbol feeds a cylinder
rod end.
Hose connections are also passed through to a rear
panel when the implement leads the drill. Hoses that go
to the same remote valve are marked with the same
color tie.
Make sure all tractor levers are in neutral or float, or
tractor hydraulics are off, before making connections.
Y1078+ Hydraulic Connections
Black (hose grips) or Yellow (ties): Fan/Fold
If your tractor has a priority circuit for hydraulic motors,
connect the fan (yellow) to this circuit.
Note: Fan hoses are not the same size. A
1 ⁄
2
inch and a
3 ⁄
8
inch hose are paired together.
Refer to Figure 15
2.
Connect the hose with the Extended-Cylinder
symbol
to the side of the circuit you choose to be
the pressure side. This hose supplies the fan (at fan
shutoff valve
) and rear port F.
3. Hook fan hose under Retracted-Cylinder symbol to
the other tractor outlet. This hose is not used by the
fan, and passes directly to rear port E.
4. Connect hose with SUMP decal to the tractor
hydraulic reservoir. Refer to your tractor operator’s
manual for instructions. The sump hose
is also
routed to rear port G.
Note: Rear ports E and F are Fold on ADI and NTA
implements.
