Starter roller and blocking bar for a conveying system of an agricultural harvester
A conveying system for an agricultural harvester includes a first belt and a second belt. The first belt and the second belt are configured to transport agricultural product along a downstream direction toward a cavity. The conveying system also includes a starter roller spaced apart from the first belt by a gap along a vertical axis. The starter roller is configured to initiate formation of a bale of the agricultural product within the cavity. Furthermore, the conveying system includes a blocking bar positioned proximate to the first belt and to the starter roller. A vertical extent of the blocking bar at least partially overlaps the gap with respect to the vertical axis, and the blocking bar is configured to block the agricultural product within the cavity from passing through the gap along an upstream direction.
