Redball 680 - Hydraulics

Hydraulics
Hydraulic quick couplers should be coupled to the trac-
tor. Make certain to correctly connect the pressure and
return line hoses to the tractor, the hydraulically driven
centrifugal pump and the fold cylinders. See the Pump
Manufacturer’s recommendations for settings on
Hydraulically Driven Pumps. As with all the steps of
installation, this should be completed with the tractor
engine turned off to assure no high pressure exists.
Tractor Hydraulic System Pressure
The hydraulic system on the Redball
®
Model 680 High
Clearance Sprayer requires from the tractor's hydraulic
system a pressure of at least 2200 PSI. A system pres-
sure less than this may not provide the force necessary
for boom functions or pump output. If you have difficulty
running the pump and/or boom functions at the same
time, check your tractor’s hydraulic. Recommended
pressure is 2500 PSI.
Hydraulically Driven Pumps
Connect the hydraulically driven pump to a tractor
hydraulic circuit with a "float" position. Use the float
position to turn off the hydraulic pump to protect the
hydraulic seals.
For tractors with an open hydraulic system, connect the
hydraulically driven pump to the priority circuit in the
hydraulic system. The priority circuit prioritizes the oil to
that circuit first and then to the others. The priority circuit
allows the pump to maintain a more consistent output in
the case you need to operate a boom function while
operating the pump. If you do not have a priority
hydraulic circuit, the pump output will decrease when you
operate both the pump and a boom function.
