Tractor Hydraulic System Pressure
The hydraulic system on the Redball
®
Model 565 Trailer
Sprayer requires from the tractor's hydraulic system a
pressure of at least 2200 PSI. A system pressure 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 pressure. Recommended pres-
sure is 2500 PSI.
Hydraulically Driven Centrifugal Pump
Refer to the manufacturer's recommendations to set the
hydraulic oil flow from the tractor to the hydraulic motor
driving the centrifugal pump. Make sure the hydraulic
flow from your tractor does not exceed these specifica-
tions causing the pump to "over speed". Over speeding
will decrease the motor seal life.
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
case you need to operate a boom function while operat-
ing the pump. If you do not have a priority hydraulic cir-
cuit, the pump output will decrease when you operate
both the pump and a boom function.

Section C
Turn off a hydraulically driven centrifugal pump using the “float”
position of the tractor’s hydraulic valve. This allows the motor
to stop slowly helping to protect the motor and motor seals.
