OrderECM's All John Deere Products collection covers PowerTech Engine Control Modules (ECM), turbochargers, and high-pressure common rail (HPCR) fuel injectors for John Deere diesel engines used across agriculture, construction, and forestry equipment. The PowerTech range spans the 2.4L, 3.0L, 4.5L, 6.8L, 9.0L, and 13.5L displacements found in tractors, combines, excavators, wheel loaders, and motor graders.

John Deere ECM part numbers use the RE-prefix, and revision levels (Level 12, Level 14, Level 14 VI) indicate the software and hardware generation of the controller — the correct level must match your engine's calibration before programming via John Deere Service Advisor. Turbocharger and injector replacements (RE535246, RE535676, RE508022, RE546784) are matched by engine serial number rather than ECM level.
