HC Boom Hydraulic Hose and Electrical Connections
Your sprayer has been shipped from the factory set-up for use with a tractor that has “Open Center”
Hydraulics. Determine if your tractor has this type of hydraulics.
Connect sprayer hydraulic hoses to the tractor hydraulic system. When the HC boom is in use ,
the hydraulic valve on the tractor MUST be locked open to assure a constant supply of oil to the
cylinder valve control bank located at the back of the sprayer.
HC Boom Electrical Connections
There are two wires that are to be connected to the tractor.
1.
Connect the RED wire to the positive (+) 12 volt power source of the tractor. The RED wire
can be connected directly to the battery or to an auxiliary connection such as the fuse block.
2.
Connect the WHITE wire to the negative (-) ground source of the tractor. The WHITE wire can
be connected directly to the negative battery or to an auxiliary connection as long as a good
ground is maintained.
If your tractor has “Closed Center” Hydraulics, turn the flow rate on your tractor hydraulic system
down to 5 to 6 GPM and try the sprayer boom functions. If the sprayer functions are not satisfac-
tory, the valve block located at the rear of the boom can be altered to operate with “Closed Center”
Hydraulic systems.
To change from “Open Center” Hydraulic system set-up to “Closed Center” Hydraulics:
1.
Locate the valve block at the rear of your sprayer on the rear tower.
2.
Locate the lower left solenoid cartridge on the face of the valve block.
3.
Remove the wire coil and open center bypass valve from the valve block. Insert the hex plug,
shipped with your sprayer into the valve block and tighten.
4.
Your sprayer is now set-up to be used with “Closed Center” Hydraulics.
Note:
If sprayer is being hitched to the tractor for the first time, charge the sprayer hydraulic system
with oil.
IMPORTANT: The storage slots for the hydraulic hoses should ONLY be used when sprayer
is disconnected from the tractor and being stored. Hydraulic hoses MUST always be con-
nected to tractor during transport of sprayer.
