  • Support structure for an agricultural machine with a floating work tool
    Patent number: 8250840
    Abstract: A support structure for agricultural implements having at least one floating head with a work tool. The support structure permits the work tool to be folded. The work tool of the agricultural implement is supported near its outer end by the support structure in a cantilevered fashion.

  • DRIVE SYSTEM FOR AN AGRICULTURAL MACHINE WITH A FLOATING WORK TOOL
    Publication number: 20110232255
    Abstract: A drive system for agricultural implements having at least one floating head and a tongue that may be disposed at various angles relative to a longitudinal angle of the implement. Two swivel gearbox assemblies are used, each comprising a first 90° gearbox rigidly attached to the implement and a second 90° gearbox that is permitted to rotate about an axis passing through one of its shafts and one of the first 90° gearbox's shaft. Because the tongue angle is variable, the drive shafts for driving the implement must take on a plurality of angles. The swiveling gearbox assemblies allow variable angles at the tongue and at the header.
