    Abstract: A roller is connected to a harvesting platform for movement with a combine over a ground surface in a direction of travel. The roller includes a first portion defining a first diameter and including a first material, and a second portion defining a second diameter and including a second material. The second diameter is greater than the first diameter. The second portion substantially surrounds the first portion, the second material has different material properties than the first material. The roller extends in the direction of travel and rotates about a second axis which extends generally parallel to the direction of travel.
