Implement Connection Example 5—Planter with Vacuum Motor and Return Line to Motor Return—With Hitch—With Lift Assist—Standard Hydraulics

RXA0126116-UN-15MAY12

A - Pressure Line

B - Return Line

C - Flow Control Valve (Wide Open)

D - Vacuum Motor

E - Planter Fold

F - Extend Coupler Line

G - Retract Coupler Line

H - Markers

I - Lift Assist Cylinders

J - T-Fitting and Hydraulic Hose

NOTE: For Ag high flow, it is recommended that the hydraulic motor be connected to the 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 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.

Connect lift assist cylinders (I) using T-fitting and hydraulic hose (J) to hitch lowering valve. The hitch lever controls the lift assist cylinders.
