Tractor Requirements
When using a 3-point boom, the tractor must have a stan-
dard Category II, Category II Quick Hitch, or a Category
III-narrow 3-point.
Before You Start
Read and understand the owners manual for your sprayer
boom. A basic understanding of how the boom works will
aid in the assembly and set up of your sprayer boom.
Before attempting to assemble the boom, use the follow-
ing as a checklist. Having all the needed parts and equip-
ment readily at hand will speed up your assembly task and
will make the job as safe as possible.
1. Check for all sprayer boom components and hard-
ware. The loose components used to fasten the
booms are packaged in a box with a packing list and
are shipped with the crate.
2. If a bolt, pin or other component has been removed, or
if you are unsure about where it is used, refer to the
parts section of this manual to identify it.
3. Have a fork lift or loader present to lift the booms
wings when assembling the sprayer boom.
4. Two people are required to assemble boom.
Sprayer/Boom
Assembly Instructions
Refer to Figure 1
1. Position the sprayer trailer in a clear, level area with
the jack placed in the park position. Adjust the jack so
that the sprayer tank is level and the elevator mast is
straight up and down.
2. Adjust the elevator located on the pull-type sprayer to
the lowest position. Refer to the sprayer Owner’s Man-
ual for elevator adjustment instructions.
3. Install the center section of the boom (16) with the
hardware (17) provided if installed on a 3-Point boom,
a TA500, or a TA520 sprayer. If the boom is installed
on another sprayer, install the hardware with the fol-
lowing modifications:
If the boom is attached to a 3P200/300 3-Point spray-
er, the 501-027S accessory kit must be purchased. In-
stall the spacer tube (4) as illustrated in Figure 2 using
the bolts (5), nuts (7), and flat washers (6).
When attaching the boom to a SA750, SA700, or
SA1000 sprayer, the 506-086V kit must be purchased.
Assemble the spacer tubes (22) as illustrated in Fig-
ure 1 in between the boom center section (16) and the
elevator using the hardware provided.
When mounting the boom on a TS sprayer, refer to
Figure 4. To mount the boom on the TS sprayer, the
506-129V kit must be purchased. Assemble the cen-
ter section of the boom onto the elevator with the
spacer blocks (1) in between.
4. Insert the level-float lock pin (21) into it's lock position,
as shown, if not already done.
5. Before installing a boom wing (14), make sure the out-
er boom frame is folded over and fastened to the inner
boom frame with the transport pin or a cable tie as
shown (13). With the outer boom frame folded, it is
easier to maneuver the boom wing during assembly.
6. To assemble a boom wing, hook the round tubing of
the boom wing (14) into the upper hinge brackets of
the center boom section. Use a forklift or loader to lift
the weight of the boom wing.
7. Assemble the pivot rod (4) and nut (3) through the
hinge components shown. Assemble the washer (8)
so that it’s smaller diameter fits down into the spring
(7). With a 1/2 inch open end wrench, hold the top of
the pivot rod while tightening the top (9) and bottom
(3) nuts to compress the spring. Tighten the nuts
evenly so they have approximately the same thread
depth on the pivot rod, and the dimension from the top
of the round pivot bar to the flat washer above the
spring is 5 3/8 of an inch. Repeat steps 5, 6, and 7 for
the other boom wing.
8. With the boom wings unfolded, assemble the 1/2" x 1
3/4" long bolts, flat washers, and flange nuts (5). Be-
fore tightening, align outer boom sections with the
center section of the boom by rotating plate (6).
Torque the nuts to 85 foot-pounds.
9. Install and center the nozzle bar (18) to the center sec-
tion of the boom with the 5/16" x 3" long bolts and
flange nuts (19). Torque the nuts to 18 foot-pounds.
10. Attach the feed-line hoses (15) from the center frame
nozzle bar to the nozzle(s) on the boom wings (14)
with the hose clamps provided.
11. Remove cap plugs on solenoid hose barbs (located
on the sprayer) and attach boom feed-line hoses (10,
11 and 12) from the three separate boom sections to
the electric solenoids with the hose clamps provided.
Make sure that the left boom feed-line hose is con-
nected to the front hose solenoid {front being toward
the hitch}. The left hose and solenoid are marked with
a red tape. The center boom feed-line hose (11) is
connected to the middle solenoid. The middle hose
and solenoid are marked with a yellow tape. The right
boom feed-line hose (12) is connected to the back so-
lenoid. The right hose and solenoid are marked with a
green tape.
If the boom is going to be mounted on the tandem axle
sprayer that has front folding booms, route the boom
hoses in front of the boom break-away pivot (4)
through the hose supports located on the front of the
boom center section and through the supports under
the sprayer trailer.
