Engine control unit for tractors and farm machines
Tractor, combine, forage harvester or irrigation pump stopped by its engine control unit in the middle of the season? We supply a genuine unit, matched to your engine serial number and shipped ready to fit.
On a farm, breakdowns always come at the worst moment: harvest, silage, irrigation. Farm machine diesel engines are often John Deere, Perkins or Cummins. We supply the engine control unit; transmission or cab controllers are not covered.
Heavy-duty diesel only — no passenger cars.
Signs of a failed engine control unit
- The engine no longer starts, or starts and then stops.
- Engine fault message on the cab terminal, engine speed locked.
- No communication with the diagnostic tool.
- Unit damaged by water, rodents (harness) or over-voltage.
These symptoms can also come from the wiring harness, the power supply or a sensor. Have the wiring checked before replacing the unit: we remind you of this in the quote.
What to send us
- The engine make and model, and its serial number (engine plate).
- The part number on the old unit's label, if readable.
- The machine: make, model, year, and whether it is down right now.
- The delivery country. Photos help but are optional.

Frequently asked questions
Is the engine unit the same as the transmission controller?
No. We supply the engine control unit only. Its part number is on its label, on the housing mounted near the engine.
Is any adjustment needed after fitting?
In most cases, no. On some tractors, additional setup with the dealer's or workshop's diagnostic tool may be needed: we tell you in the quote.
Do you supply irrigation pump engines?
Yes, when the engine is an industrial diesel (John Deere, Perkins, Cummins…). Give us the engine brand and serial number.
