Rate Controller parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Controller Board 2 parts 1× Rate-control board that closes the loop on metering speed.
2 Cab Display 2 parts 1× In-cab terminal showing rate, area and alarms.
3 GPS Receiver 1× Receiver feeding position for variable-rate maps and section control.
4 Section Sensor 6× Row-clutch sensor that confirms seed flow and shuts off overlapped sections.
5 Wire Bundle 1× Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
6 Connector 18× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
