Looking for a replacement roller sprocket for a Deutz-Fahr GP 2.30 round baler. The roller in question is the second one up from the pickup and directly below the double sprocket drive. New genuine part is very expensive so looking for a second hand one. If anyone has any spares or knows of anyone breaking one it would be a massive help. Believe the part number is VF16518551 but this may be wrong. Any help would be appreciated.
