Patent CA-2109290-A1 (CA)
Title: Partial Width Seeding Attachment
Inventor: LONG JOHN D
IPC: A01C7/08
Filed: 1993-10-26
Abstract: A partial width seeding attachment includes electronically controlled solenoids which activate hydraulic flow control valves connected to the hydraulic cylinders on respective implement sections.  Switches in the tractor cab control the rockshaft of one or more selected sections independently of the other sections to raise the openers on the selected section or sections from contact with the soil. An electronically activated flow reversing valve is connected between the source of hydraulic fluid under pressure and the lift cylinder for each of the sections.  Activation of a selected valve after the selective control valve on the tractor is moved to the normal field working position pressurizes the side of the cylinder that raises the openers on the section.  The remaining cylinders operate normally to maintain preselected down pressure on the other openers.  A master raise switch provides implement lift independent of the position of the individual rockshaft control switches.  A latching relay connected to a momentary on switch prevents valve operation without manual switch movement after a power interruption.
