Install Section Air Lines
All of the tanks and valve inlets are interconnected,
forming a single shared reservoir system.
On a smaller planter, this topic is a simple connection of
a single tank
and valve . Use a tee at the
inside end of the tubing, for the supply connection.
Refer to Figure 22
137. Locate the left
and right extents of the tank
and valve set now installed.
138. Route tubing between these ends. Stay at the
upper rear edge of the tool bar, except at inboard
wing ends. At wing pivots, follow the existing seed
hose and harness bundles.
139. Make end connections using push-lock fittings or
couplers .
140. Select as many tees as needed to make
connections between ends. Select one additional
tee for use as supply line, inserted and connected in
the next topic.
Install Supply Air Lines
The supply line from the hitch connects to the section
line:
• On a folding planter, the line is routed inside the left
pull bar, and connects to the section line on the left
wing.
• On a 3PYP/A planter, the line is routed from the hitch
and connects to the section line at machine center.
141. Use the final tee to splice into the section line at the
point where the supply line is expected to meet it.
142. Route the remaining tubing from the hitch to the
section connection point.
143. If the compressor is tractor-mounted, cut the supply
line near the hitch and insert a coupler.
144. Connect the end of the supply line to the pump
outlet.
145. Install and secure the compressor cover.

Fish Line Bind
If the wire or tape cannot be fished through the left pull
bar of a folding planter, it is necessary to re-pull the
entire hose/harness bundle, with the tubing added.
a. Connect each hydraulic hose at the hitch to a
hydraulic source that has a Float capability. Set the
circuit to Float to relieve pressure in the hose.
b. Identify each hose inside the left pull bar with tape
and marker. Determine which hose end is easier to
disconnect. Mark the other side of each connection.
c. Carefully crack each JIC connection to relieve any
unexpected residual pressure. Disconnect each
connection and drain it into a bucket.
d. Mark and disconnect any harness routed through
the pull bar.
e. Connect a fish line to the disconnected end of a
hose or harness.
f. Pull the hose and harness bundle out.
g. Add the supply tubing to the bundle.
h. Attach the bundle to the fish line. Pull the bundle
through the pull bar.
i. Re-establish all connections.
j. Perform a bleed before performing any hydraulic
lifts or folds.
