Hydraulic Connections
Black: Fan/Fold
If your tractor has a priority circuit for hydraulic motors,
connect the fan black 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 11
7.
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.
8. 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.
9. 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.
Sump First and Last
Machine Damage Risk:
Seals in the hydraulic fan motor can be damaged if the return
line is pressurized. Always connect the SUMP hose first and
disconnect it last. The sump hose has a larger (1.06 inch)
quick-connect coupling.
Refer to Figure 12
Note: For proper hydraulic flow, use a poppet-style,
Pioneer quick coupler to connect sump hose to
tractor.
Green: Auger/Marker (& Fold on ADI)
Connect green-coded hoses to tractor outlets capable of
continuous flow (although less than required for the fan).
This circuit is used by the cart for the auger, and may
also be directed to rear ports A and B for use by Markers
(not all implements have Markers).
A diverter valve on the cart ( in Figure 11) switches flow
between auger and rear ports.
Blue: Implement Lift
Connect blue-coded lift hoses to tractor outlets. This
3 ⁄
8
inch hose circuit is unused by the air cart, passing
through to rear ports C and D. It is used for Lift by all
implements.
Storage
To lengthen the life of the bin seal, store the cart with the
bin lids closed but unlatched.

Pump Damage Risk:
For CTA implements, some tractors require an auxiliary flow
kit to prevent damage to the hydraulic pump. Contact a service
technician who is factory trained on your tractor before
hooking to cart and CTA implement.
Pump or Motor Damage Risk:
Failure to properly plumb sump hose into tractor hydraulic
reservoir may result in tractor or drill damage.
Note: NOTE: SAE O-ring and JIC 37-degree, flare-type
hose connections do not require sealant for
reconnecting. They do not require high torque for
a good seal.
