Abstract: A mower with a hitch system allows large lateral offsets in both directions of the mower relative to a towing vehicle. The mower hitch system includes first and second swing arms spaced apart across the mower. First and second pivot shafts mount the respective first and second swing arms on the mower for pivotal movement of the arms about respective upright axes spaced apart across the mower. The swing arms extend towards a front end of the mower for connecting to lift arms of a three point hitch on the towing vehicle. A lug extends from the first pivot shaft such that the first swing arm and the lug form a bell crank. A hydraulic cylinder mounted on the front end of the mower connects to the lug such that extension and contraction of the cylinder pivots the first swing arm laterally over the cylinder and across the mower. The towing vehicle also includes a power take off for connecting to a telescoping drive shaft assembly with universal joints on the mower.

Abstract: A foliage harvester is provided, as is a mechanical drive arrangement which includes a pivotally mounted main gearbox. An extension assembly extends forwardly with respect to the main gearbox for a relatively short length, and a connection assembly operatively joins the rotating portion near the rear end of the mechanical drive assembly in a manner which prevents substantially any side-to-side or generally horizontal movement between that portion of the mechanical drive assembly and the rotatable main gearbox. At the same time, this operative joining incorporating use of the connection assembly permits limited up-and-down or generally vertical movement of the mechanical drive assembly with respect to the pivotable main gearbox. In an especially preferred arrangement, the implement is a center pivot mower conditioner, and the mechanical drive operates the cutting and conditioning assemblies during operation of the mower conditioner on either side behind the towing vehicle or tractor.

Abstract: A header includes a substantially rigid header frame having a main longitudinal rear tube and a plurality of beams extending downwardly and forwardly from the main tube to a cutter bar which is maintained substantially straight and parallel to the main tube. Adjustment of the longitudinal shape of the cutter bar is effected after the header is assembled by operating screwjacks on two inner beams which cause plastic bending of the beams to raise or lower a center portion of the cutter bar so that when assembled the cutter bar is longitudinally straight or slightly upwardly concave. This adjustment after the assembly is complete allows the cutter bar to be adjusted to the required longitudinal shape for optimum cooperation with the reel.

The driveline incorporates a clutch assembly mounted on the input shaft of a bevel gearbox. The forward end of the input shaft is formed with a conical surface that mates with a corresponding conical hub bore formed within the clutch assembly. The end of the input shaft is formed as a truncated cone to provide a gap between the end of the shaft and the bottom of the bore and assure a proper seating of the two members.
