A metering wheel includes a shaft having a longitudinal axis, a plurality of first wheel sections, and a plurality of second wheel sections. Each first wheel section has a fluted exterior surface and is rotatably coupled to the shaft. Each second wheel section has a cylindrical exterior surface and is co-axial with the shaft and rotatable independently of the shaft. In another aspect, at least one of the plurality of first wheel sections has a plurality of protrusions on the exterior surface defining a plurality of valleys therebetween, wherein at least one protrusion does not extend an axial length of the first section. In yet another aspect, a metering assembly comprises a metering wheel and a chute divider. The chute divider comprises a wall positioned proximate a longitudinal mid-point of one of the plurality of first sections or one of the plurality of second sections. |
