Secondary seed hose is 1 inch (2.5cm) in diameter and
is provisioned in 100-foot (30.5m) rolls. The raw hose is
cut-to-length to connect each distribution tower outlet
(port) to a row unit seed tube.
Port Numbering Convention
Tower ports are numbered:
1-8
on 3N-4010HDA-4810 or
1-11 on 3N-4010HDA-6675
Ports are numbered in ascending order, clockwise
around tower. Port one (1) is the port closest to the cen-
ter of the tower-mounting plate
. This corresponds to:
on wing towers (1, 2, 5, 6): rear-most port
on center towers (3, 4): port closest to drill center.
Note: If blockage detectors are to be installed, it is bene-
ficial to record the opener row number at each tow-
er port opening, using a permanent marker, on the
tower top cap.
Start with Tower 1 (left wing, left tower).
Refer to Figure 27 on page (shown exploded for clarity)
77. Loosen, but do not remove, four (4) nuts
