360 Y-DROP

INTRODUCTION
Before beginning, it’s important to know where each mounting bracket fits relative
to the row spacing involved. The 360 Y-DROP unit should be precisely centered
on the machine, as this is critical to the assembly of the system to the sprayer and
for mounting the system to your sprayer boom. There are, however, many boom
variations among all sprayer models. Your sprayer may not be identical to the model
in the following steps of the guide, and the pictures may not exactly reflect your
model. While these steps will help you install most of your 360 Y-DROP system,
you may need to custom-fit some components with your particular boom.

Ratchet wrench with 1/2” and 9/16” deep well sockets
3/8” 12-point socket
1/2” and 9/16” combination wrenches

ESTABLISH
DROP LOCATIONS
Figures 1 and 2
Step 1
Locate the center of the machine and
identify the location of all the drops. On
the sprayer boom, mark where each riser
mount will be located. This will ensure
that the extension tubes will not interfere
with the riser mounts.

Step 2
Starting at the wing fold pivot pin on
the primary boom, measure and mark
points at 32", 86", 156"; 213" and 277"
(all measurements are ±5"). Repeat for
the other primary boom.
