Control Units and Modules

Control units and modules are the electronic brains on a modern tractor: engine and transmission control units, hitch controllers, steering control units, electronic support units, cab switch modules and the modules behind lighting, PTO and hydraulic functions. The range is supplied by John Deere part number with fitment, and each page lists superseded numbers so an older unit can be matched to its current replacement.

Ordering a control unit

Order by part number and check the serial number range on the product page, because a control unit is often specific to a production break within a model. Some units need dealer programming after fitting; the product page states this where John Deere lists it. Call 01522 440522 with the tractor serial number to confirm before ordering a high-value unit. The sensors and switches that feed these units are under sensors and senders and switches.
