This hydraulic cleaning element removes crop residue and debris from the baler chamber during the baling cycle. It is mounted in the housing that directs airflow across the pickup and rotor area, preventing material buildup that can reduce bale density and throughput. A clogged or worn cleaning element allows residue to accumulate, leading to uneven bale formation and increased load on the drive system. As an original component, it matches the housing's internal profile and sealing surface, ensuring the air stream is directed correctly without leakage.
