Part of the John Deere Repair Manuals.
Fits the John Deere 2254, 2256, 2258, 2264 and 2266 combines from serial number 067766, European version, both standard and Hillmaster machines. The 2254 runs the John Deere 6068 engine and the other four run the 6081. Technical manual TM4594 puts both halves in one file: repair sections 05 to 140 and operation and tests sections 210 to 340.
The electrical system is covered twice, split at serial number 068568/068569, so check your type plate before you chase a wire. You get functional schematics, harness diagrams, hydraulic circuit diagrams, Infotrak and ContourMaster error codes, and hydrostatic pressure tests.
