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.
