A harvesting header has an outer impeller fixed to an outermost outboard cutter for rotation therewith to convey cut crop material laterally inwardly toward the center of the header. The outer impeller has a lower disc member forming the bottom of an impeller cage and an upper stationary grass ring. An intermediate impeller is located between the axes of rotation of the two outboard cutters, wherein the intermediate cage-like impeller is suspended on the harvesting header above the cutting plane and not fixed to any of the cutters and rotates in the same direction as the outboard impeller. The outboard and intermediate impellers have a plurality of crop conveying discs, wherein the crop conveying discs on the outboard impeller are offset vertically and overlap horizontally with the crop conveying discs on the intermediate impeller to form an intermeshing region between the two impellers.

A working vehicle has a castor wheel assembly selectively providing steering assist. A pivoting caster spindle coupled with a caster wheel and an engagement plate connected to the caster spindle in a fixed manner such that the engagement plate pivots with the caster spindle. A pivoting steering arm is rotatably connected to the caster spindle and a steering cylinder is connected to an outward end of the steering arm with a tie rod configured to pivot the steering arm. A keyed connecting mechanism selectively couples the steering arm with the engagement plate. In an engaged position, the keyed connecting mechanism couples the steering arm with the engagement plate such that the steering cylinder pivots the caster spindle and caster wheel. In a disengaged position, the steering arm is uncoupled with the engagement plate such that the caster spindle and caster wheel are free to pivot independent of the steering cylinder.

A crop harvesting header has a cutter bed to cut crop material as the harvester advances through a field. The cutter bed includes a plurality of rotatable cutters having knives extending from opposing ends of the cutters. Each cutter is ninety degrees out of phase with respect to its adjacent cutters such that the circular paths of travel of the knives of adjacent cutters overlap one another, and adjacent cutters rotate in opposite directions. Each cutter has a generally elliptical knife carrier, and a pair of knives at opposites ends of the carrier, wherein a portion of each knife extends beyond the end of the carrier to expose a cutting surface to sever the standing crop. The cutter also includes an attachment device connecting each knife to the knife carrier, and a fixed stop restricting rotational movement of the knife with respect to the carrier about the attachment device.

A modular rotary cutter bed is formed by a series of essentially identical cutter modules mounted end-to-end along the length of a common support beam. Guards for the cutters of the modules are arranged such that each guard overlaps and bridges the seam between an adjacent pair of modules so as to increase the structural rigidity of the cutter bed. Each guard is attached at its front end to the noses of a pair of adjacent modules and at its rear end to the support beam to increase structural integrity in all directions. A second embodiment does not utilize a common support beam for the modules but instead relies upon the interconnections between adjacent modules and bridging overlap of the guards to rigidify the cutter bed.
