A harvester for root crops such as beets is provided which preferably provides continuous flow of root crops from a header, along a transfer assembly, through a processing run, and to an elevator assembly. A data stream comprising a plurality of data segments is received. A guide with which the holding structure may be guided to an unbalance compensation site of the attachment surface and pressed thereto. Knurling on the opposite side provides more static friction against the wheel surface. Further, a smaller and more reliable die package is achieved and circuit parasitics are reduced due to the reduced signal path lengths.
