Connecting a hydraulic implement to SCVs is recommended for most of following applications. Power beyond may be required in some applications
1
.
Hydraulic Cylinders:
-
Connect to SCV couplers
-
Adjust flow rate and detent time
Hydraulic Motors:
IMPORTANT:
Some motors are not equipped with over-speed protection. Extended operation above recommended speed could cause failure.
Using Selective Control Valves:
-
Connect to SCV
-
Connect motor seal drain line to motor seal drain coupler
-
Connect motor inlet hose to retract SCV coupler
-
Adjust flow rate and set detent time to continuous "C"
-
Connect motor return hose to power beyond return coupler
OR
connect motor return hose to SCV extend coupler using check valve
-
Operate motor between "retract" and "float"
Using Power Beyond:
-
Power beyond may be used for motor applications which have pressure compensated flow controls

Implement Auxiliary Control Valves
See Implement Connection Example 1-Implement Control Valves in this section.
|
Open or Closed-Center Valves with Unloading Valve:
-
Connect pressure and return line to SCV coupler
-
Adjust flow rate and set detent time to continuous "C"
-
Connect return line to power-beyond return coupler
Closed-Center Valve with Load-Sense Port:
-
Connection to power beyond is recommended.
Closed-Center Valve without Load Sensing:
-
Connect to power beyond
1
-
Connect to SCV
NOTE:
Tractor hydraulic system will operate at high pressure. Increased hydraulic oil temperatures may result, if other functions are operating at continuous flow.
Power beyond may be required in some applications
1
:
-
Tractor SCV control is not needed-implement equipped with independent control valve
-
Implement control valve requires external load sense signal to prevent pump operation at high pressure
-
No other SCV outlets are available
