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 specifications caus-
ing the pump to "over speed". Over speeding will
decreasing the motor seal life.
Hydraulically Driven Diaphragm Pump: This pump
assembly has a pressure compensated flow control pre-
set at the factory allowing 10 Gallons per Minute to the
pump's motor. The excess is returned to the tractor
through the return line. No further set up is required.
Refer to the pump manufacturer's recommendations for
installation instructions.
Directional Stack Hydraulic Boom Function
Controller
The Redball
®
Front Fold Boom Directional Stack
hydraulic controller utilizes "live" hydraulics. This elimi-
nates the need to move the tractor's hydraulic controls in
the direction desired to operate a boom function. Once
the setup is complete, the operator will engage the trac-
tor hydraulic controls connected to the Directional Stack
in one direction and leave the circuit engaged.
Movement of the toggle switch for a boom function will
signal a valve in the Directional Stack to direct the
hydraulic oil in the correct direction and operate the
boom function selected.
Verify with your tractor manufacturer if you have an open
or closed hydraulic system in your tractor. The
Directional Stack comes configured for the majority of
closed hydraulic systems. In this configuration, the man-
ifold does not allow the hydraulic oil a path back to the
return side of the manifold. This configuration counts on
the tractor's hydraulic system to turn off the flow of
hydraulic oil to the manifold when no boom functions are
needed.
