Boom & Attachment
Plumbing Instructions
Refer to Figure 8 on page 18
1. 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 center boom feed-line hose from the corre-
sponding female fluid connector to the middle sole-
noid marked with yellow tape. Now aconite 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 bellow the tractor, or rubbing on the tractor
frame when in operation. Route boom hoses
through the remaining hose guard material along
the front side of the left-hand tank.
2. If the Great Plains side-mount tanks are being
mounted with another implement, route and connect
the hoses to the solenoid valve as described in (1)
above.
Tractor / PTO Pump Hook-Up
1. With the tractor not running, position the PTO pump
on the tractor’s PTO shaft with the coupler bolt loose
on the splined end.
2. Push the coupler of the pump on to align with notch
in the tractor PTO shaft and install bolt.
3. Make sure there is adequate hose length to reach
the pump.
4. If you have a 540 RPM pump or a 1000 RPM 1 3/8
inch spline pump, torque the 1/2 inch Grade 8 cou-
pler bolts to 105 ft-lbs. If you have a 1000 RPM
1 3/4 inch spline PTO pump, torque the 5/8 inch
Grade 8 coupler bolt to 210 ft-lbs and the other 1/2
inch Grade 8 coupler bolt to 105 ft-lbs.
5. Rotate the PTO shaft by hand to make sure the bolts
clear the PTO shielding.
6. Attach the torque bar chain to the drawbar securely.
7. Hook the tarp strap in such a way that the slack in
the chain is taken up slowly when the PTO is en-
gaged so the torque bar does not bang.
8. Tie up any loose hoses with cable ties to prevent
hose damage.
Tractor / Hydraulic Pump Hook-Up
1. Your tractor should be equipped with at least two re-
mote outlets (one pair).
2. If your tractor has an open-center hydraulic system,
remove the orifice restrictor in the pressure line. If
your open-center hydraulic system produces more
than 15 GPM, it is not recommended to hook this hy-
draulic pump up to your tractor. Without a flow divid-
er of adequate capacity the pump will spin too fast. If
your open-center hydraulic system is 15 GPM or
less, it is recommended to install a hydraulic flow di-
vider so that you can adjust the speed of the pump.
A Gresen model number CFDA or similar flow divid-
er will work. The maximum flow for the hydraulic mo-
tor is 6 GPM.
3. For the hydraulic motor to turn in the right direction,
the pressure hose must be connected to the "A" port
of the motor and the return line connected to the "B"
port. Install hydraulic hose clamp label provided {re-
fer to hydraulic pump section in parts manual}
approximately18 inches from tractor quick couplers
so that the hydraulic cylinder retract symbol and ar-
row aligns with the pressure hose going to motor
port "A". If your tractor is a John Deere, leave the
restrictor in the pressure side of the hydraulic pump.
If your tractor has a closed center hydraulic system
and is not a John Deere, remove the restrictor.
4. If your tractor has a closed-center system, or a flow
divider has been installed in your tractor’s open-cen-
ter system, set the hydraulic flow control valve at a
minimum flow for the pair of outlets that operates the
pump.
5. With water in the sprayer tank, and water in the
pump, place the hydraulic lever in the float position
and start the tractor.
6. Place a stop in the neutral position of your tractor hy-
draulics so that the lever can only be moved to the
float and down positions. Refer to your tractor oper-
ator’s manual or tractor dealer on information for the
neutral stop.
IMPORTANT: DO NOT move the hydraulic lever into
the neutral position while the hydraulic pump is run-
ning. To do so may cause damage to the hydraulic
pump.
7. To set the hydraulic flow control on the tractor, first
engage the pump by placing the hydraulic lever in
the down position. Once the system builds pressure,
close the agitation valve, shut off the boom section
switches and close throttling valves {if applicable}.
