摘要： Device for mowing crops, comprising a series of mowing units arranged side by side at predetermined distances, each mowing unit comprising a knife holder with at least one knife carrying portion for carrying a mowing knife, and a drive mechanism for each knife holder. The drive mechanism for each knife holder comprises a first drive element comprising a hub portion for carrying the respective knife holder, and a second drive element drivingly engaged with the first drive element to rotatingly drive the knife holder about a vertical axis. In normal operation, the knife holder and the hub portion form a unitary rotatable assembly which, at a position between the knife carrying portion and the hub portion, is provided with a break connection which is effective in a radial direction.

摘要： A suspension system for agricultural implements having at least one floating head using a four-bar linkage and permitting the floating head to accommodate variations in ground surface elevation in a lateral or transverse direction. By permitting the floating head to float, a more consistent cutting height is realized when ground surface elevation varies in a transverse direction. A main frame is provided to which the ground engaging wheels are attached. A sub-frame is connected to the main frame via the four-bar linkage. The sub-frame is pivotally attached to the arms of the four-bar linkage by spherical bearings.

摘要： 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.

摘要： A swing cylinder such as those used to offset an agricultural implement may experience larges forces as it reaches the ends of its travel. A cushioning system to mitigate these forces comprises a piston with wear rings engaged thereto. The wear rings block off a usual passageway for the hydraulic fluid to flow, and provide their own, much smaller passageway. The flow of hydraulic fluid is thereby restricted in the neighborhood of the extremes of piston travel. An additional aspect of the invention is that the wear rings are pushed out of their position blocking the passageway when hydraulic fluid pressure is applied to move the piston away from the extreme position, thereby completely removing the restriction to flow in that direction.
