C - Flow Control Valve (Wide Open)

D - Vacuum Motor

E - Control Valve

F - Lift Assist

G - Markers

H - Extend Coupler Line

J - Implement Lift Assist

K - 9-Pin Implement Connector

L - 9-Pin Connector for TouchSet™ Depth Control

NOTE: For Ag high flow, it is recommended that the hydraulic motor is connected to top SCV’s (45cc high flow pump).

Not recommended for high flow scraper hydraulics.

In this application vacuum motor (D) receives pressure oil from the retract port of SCV. Return oil is routed to power beyond return port. If return hose is equipped with special planter return hose tip, it can be connected directly to left-hand side of coupler three. When the motor is shut off, the SCV lever is moved to float position to allow motor to coast to a stop. Moving lever to neutral will cause motor to stop abruptly and may damage seals.

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 at the same time outside air temperature is high.

Implement lift assist (J) controlled by hitch lever when activating hitch valve.

SCV #1 is used to control both the hitch valve and lift assist. The 9-pin implement connector harness (K) contains a loop circuit that disables tractor hitch control unit when it is connected to 9-pin connector for TouchSet™ depth control (L) that is wired into tractor main electrical harness.
