Abstract:
1. In combination with a mowing implement including a rotary disc cutter bar extending transversely to a direction of travel during mowing operation and including transversely spaced, knife-carrying rotary discs, structure aiding in converging cut crop toward a discharge zone located behind the cutter, comprising: at least one converging drum having an upright axis of rotation located behind a line of centers of said cutter bar and being located upstream relative to crop movement toward said discharge zone and adjacent at least one of said rotary discs; and said at least one converging drum having a lower end including an outer peripheral edge located a first distance vertically above a path followed by knife blades carried by said at least one of said rotary discs and including an inner region surrounding said upright axis and located a second distance, which is greater than said first distance, above said path, thereby creating a relief area beneath said at least one converging drum; and said relief area being devoid of any further structure so as to allow crop to move into said relief area.
