Installing Fertilizer Arms
The fertilizer arm kit (GP part no. 164-140A) contains all
parts needed to convert one coulter into a fertilizer injec-
tion coulter.
To assemble one fertilizer arm:
Refer to Figure 2-7.
1. Assemble the fertilizer arm (1) to the coulter swing
arm (2) with two 1/2” x 1 3/4” bolts (3), 1/2” flat wash-
ers (4), 1/2” lock washers (5) and 1/2” nuts (6).
2. Slide the fertilizer arm (1) up or down to the desired
position and tighten hardware.
3. Install the solid stream nozzle (7) in the lower end of
the fertilizer arm (1) and tighten. Install the hose-barb
fitting (8) in the upper end of the fertilizer arm (1) and
tighten. Use pipe sealant on the pipe-thread connec-
tios. Repeat above steps for remaing arms.
4. Use roll of 3/8” hose from manifold kit to connect each
nozzle body to a fertilizer arm (1). For each nozzle
body, insert hose onto nozzle barb at manifold. Route
hose down to fertilizer arm (1), pulling hose straight but
not taut. When satisfied with hose length, cut hose.
Connect hose to hose-barb fitting (8).
IMPORTANT: Do not cut hoses longer than 3 feet. You
will not have enough hose for all nozzles if hoses are
longer than 3 feet.
