Lift System
Hydraulic Hose Connections
Uncoil the hoses from the first and the sixth frame sec-
tions and route them on the frame as shown in Figure 1-6.
The hoses from the rod end of the outer-most wing cylin-
ders will connect to the elbows on the flow divider on the
center frame. The hoses from the base end of the wing
rear lift assist cylinders will attach to the rod end of the
master cylinders on the center section. Secure the hoses
to the frame with the 22” long cable ties provided. Avoid
routing the hoses where they could get pinched or worn
from folding, unfolding, raising, or lowering the implement.
Do not let the hose rub on sharp edges and make sure
there is enough slack for down flex of the wing sections.
NOTE: The SAE O-Ring and JIC 37˚ flare type hose
connections do not require sealant for reconnecting.
They do not require high torque for a good seal.
Do not try to raise or lower implement until circuit is bled of
air. Refer to the Bleeding the Hydraulic Lifting System, this
section starting on page 16.
Fold Cylinders
!
DANGER!
The folding cylinders must be bled free of air and implement
should be hooked to cart and tractor before attempting to fold
implement, otherwise severe property damage and bodily dam-
age or death could result.
Position the main and outer fold cylinders with base ends
toward the center of the drill. Pin the base ends to the fold
cylinder lugs. Secure the pin with the provided clip, refer to
Figure 1-7. Leave rod end unhooked and block up in the
air so that the rod will not come into contact with any ob-
ject when extended. Do not connect rod end until after air
is bled from fold circuit.
