A sprocket assembly adapted for rotational cooperation with a flexible, toothed driving belt and used in a crop handling device such as a forage harvester or the like is constructed of a pair of parallel sidewall members or disks which are interconnected by a central hub rotatable about a center axis. The outer surface of the hub is contoured so as to include a middle section of reduced diameter together with additional sections of generally conical configuration extending away from the middle section toward the sidewalls. Sets of drive lugs are provided on the inner surfaces of each of the sidewalls and arranged in a circular pattern so as to cooperate with the teeth of the drive belt. A stationary wiper arm is mounted adjacent to the rotatable hub and includes a portion extending into the space between the sidewalls and between the two sets of drive lugs such that an end portion of the wiper arm is positioned in close proximity to the middle section of the hub. Foreign material carried into the sprocket assembly by the drive belt winds about the hub surface and is channelled by the conical sections thereof toward the middle section whereupon the wiper arm disintegrates the material and ejects it from the assembly.

A row crop harvesting apparatus adapted to sever forage from a field and deliver it to a crop processing mechanism. The apparatus includes two elongated, laterally opposed conveyor belts which define between them a crop receiving passage. The design of the belts on either side of the crop receiving passage preferably comprises a driving member, a forward idler, and longitudinally spaced intermediate idlers. The idlers are spaced so that idlers of one belt are not laterally aligned with idlers of the other belt. The apparatus includes a rotary cutter mounted and driven by an adjustable forward idler. Means are provided for adjusting the adjustable forward idler. The rotary cutter cooperates with a second cutter element mounted on the means for adjusting the adjustable forward idler, thereby allowing the forward idler to be adjusted without affecting the cutting relationship of the rotary cutter and the second cutter element.
