Publication number: 20090101373Abstract: A transport lock joint is provided for an implement with a center section and wing sections adapted for stack folding to transport positions over the center section. The lock joint includes an insert element mounted on one of the wing sections and a retainer element mounted on the other wing section. With the implement in its stack-folded transport position, the insert element is received within the retainer element and the wing sections are mutually restrained against relative movement, particularly relative movement associated with the over-the-road travel. Unfolding the implement to a field working position disengages the lock joint by extracting the insert element from the retainer element.Type: ApplicationFiled: December 23, 2008Publication date: April 23, 2009Applicant: Bigham Brothers, Inc.Inventor: Von D.

Patent number: 7478683Abstract: A lift system includes parallel connected cylinder circuits with cylinders mechanically tied together on a first lift wheel arm. The base end of a third cylinder connected to a second lift wheel arm is connected in parallel with the pair of cylinders. The rod end of the third cylinder is constrained for movement with the rod end of a fourth cylinder also connected to the second wheel arm. The rod end of one of the pair of cylinders is connected in series with the base end of the fourth cylinder to thereby constrain the third and fourth cylinders on the second lift wheel arm to move in unison with the pair of cylinders on the first lift wheel arm. Series cylinder circuits move the wing cylinders in unison with the main frame cylinders to keep the implement level. The hydraulic circuit is also plumbed to retract outer wing wheels during wing fold operations to eliminate outer wing wheel interference.Type: GrantFiled: July 29, 2005Date of Patent: January 20, 2009Assignee: Deere & CompanyInventors: Donald Ray Peck, David Carl Winter, James T.
