Implement Connection Example 6—Integral Planter with Hitch Auxiliary Raise, Hitch Cylinders Controlled by SCV in Parallel with Hitch Auxiliary Raise

RXA0113671-UN-31MAR11

Implement Connection Example 6 (SCV Controlled)

A - Pressure Line

B - Return Line

C - Flow Control Valve (Wide Open)

D - Vacuum Motor

E - Control Valve

F - Hitch Auxiliary Raise

G - Marker

H - Extend Coupler Line

I - Retract Coupler Line

J - 9-Pin Connector with Harness

K - Hitch Auxiliary Raise

In this application, vacuum motor (D) receives pressure oil from retract port of SCV. Return oil is routed to power beyond return port. When motor is shut off, SCV lever is moved to float position.

Control valve (C) is wide open and flow is controlled by tractor control panel. If valve is used to control oil flow, pump will operate at maximum pressure which may cause overheating of hydraulic oil if operating when outside air temperature is high.

In this configuration, SCV I is used to control both hitch valve and hitch auxiliary raise. The special 9-pin connector with harness (J) contains a loop circuit that disables tractor hitch control unit when it is connected to 9-pin connector that is wired into tractor main electrical harness.
