3-Point/Boom
Assembly Instructions
1. Refer to Figure 5 on page 13 to determine the pin and
spacer configuration needed for your tractor.
Mount the 3-point attachment (1) to a tractor with the pins
provided.
Make sure that the 3-point attachment is level so that after
the boom is assembled it will not hit the tractor when the 3-
point is raised.
2. Follow Step 3 through Step 10 under Sprayer/Boom
Assembly Instructions beginning on page 10 to com-
plete the assembly of the boom.
Refer to Figure 6
3. Attach the fold bracket (4) to the 3-point attachment
(1) with the four 1/2" x 4" long bolts (5), 1/2" flange
nuts (7), and flat washers (6). Assemble the coupler
bracket (8) as shown when you assemble the fold
bracket.
4. Fasten the male fluid connectors (2) to the coupler
bracket (8) with the coupler clamps (9). Use the 5/16"
x 3/4" long bolts and 5/16" flange nuts to secure the
coupler clamps.
5. Attach boom line hoses from the three separate boom
sections to the cam-lock male fluid connectors (2) with
the hose clamps provided. Make sure to route the
boom hoses behind the boom break away pivot (Fig-
ure 1 (4)) so that when the boom folds to the back, the
hoses will not stretch. You will need to route the hoses
from your tractor to the cam-lock female fluid connec-
tors (3), which fasten into the stationary male fluid
connectors mounted on the 3-point frame.
6. If the 3-point boom is being mounted on a tractor with
Great Plains side-mount tanks, remove the cap plugs
on the solenoid hose barbs and route the left boom
feed-line hose from the corresponding female fluid
connector to the right solenoid {right being as you sit
in the tractor} marked with red tape. Connect the cen-
ter boom feed-line hose from the corresponding fe-
male fluid connector to the middle solenoid marked
with yellow tape. Now connect the right feed-line hose
from the corresponding female fluid connector to the
left solenoid marked with green tape. Take care when
routing the boom hoses to the tractor to ensure there
will be no kinking, drooping, hanging below the tractor,
or rubbing on the tractor frame when in operation. Use
cable ties to fasten and protect the hose.
7. Fold and unfold the boom wings and check for any
pinch points where the hose may become damaged.
Unfold the boom, remove the boom level float lock pin
(Figure 1 (21)) and rock the boom to check any pinch
points around the swing bars (Figure 1 (20)). Use the
included cable ties to fasten the hoses in such a way to
prevent hose damage.
8. Check to see all nuts are tightened. See Torque Val-
ues Chart for Common Bolt Sizes in Appendix for ad-
ditional torque specifications. Check to see that all
hose clamps are tight.
Fill the sprayer tank 1/4 full of water. Hook up the pump to
a tractor and operate the pump with the control box boom
switches off and the agitation wide open. If unit is
equipped with solenoid throttling valves open throttling
valves full open. With the pump running, turn on all the
boom switches and flush out the boom lines before as-
sembling the nozzles. Allow water to flow out of all nozzles
at least ten seconds to ensure all foreign matter is re-
moved from the plumbing.
