The shredding assembly includes a shredder configured to shred received crop material; and a shredder pan carried by the chassis under the shredder that includes a shred assister configured to cooperate with the shredder to shred crop material and at least one track follower in contact with the track that allows the shredder pan to move along the track toward the rear of the chassis.
