A drive roller for a crop conveying belt has a cylindrical roller body having an outer surface surrounding an axis of rotation of the roller for engaging an inner drive surface of a canvas wrapped therearound. The roller has a plurality of raised spaced elements such as ribs formed of a hard wear resistant material such as carbide clad onto the outer surface metal of the roller body. The ribs extend along a part only of the body at the two ends in an axial direction and angularly spaced around the outer surface. The ribs have a height less than 6 mm and a width less than 6 mm arranged such that the ribs do not engage into any recesses in the drive surface of the belt.
