Intake fingers and finger assemblies for use with intake portions of harvesting assemblies, on harvesting machines such as combines, haybines, bailers, corn pickers, and the like. The fingers and finger assemblies cooperate with crop-gathering augers, and crankshafts inside the augers, in feeding cut crop material toward discharge portions of such harvesting assemblies. The fingers extend and retract through apertures in the auger cylinder according to an eccentric mounting of the finger crankshaft inside the auger cylinder. A respective finger comprises a reinforced polyester or polyurethane shaft, and a polyurethane sleeve overlying a crop-engaging end portion of the finger, such as along 50% to 80% of the length of the shaft. In preferred embodiments, the shaft is reinforced with fiberglass or other fiber, the composition of the sleeve comprises polyester-based thermoplastic polyurethane, and the sleeve has a hardness of about Shore D-45 to about Shore D- 70.
