Additional Notes

  • On the Case-IH MXM PRO series, the power steering fluid capacity figures listed apply to a combined transaxle, hydraulic system, and power steering reservoir rather than a dedicated steering-only circuit. Large-frame agricultural tractors commonly share a single fluid sump across these three functions, which accounts for the notably high volumes involved.
  • The MXM120 PRO and MXM130 PRO both carry an 80-liter Powershift capacity for the combined system. Sharing an identical figure across two model designations indicates the same transmission and hydraulic hardware is used in both variants despite the difference in rated engine output.
  • The MXM140 PRO and MXM155 PRO step up to a 90-liter capacity, reflecting a larger shared sump compared to the two lower models. The 10-liter increase between the 80-liter and 90-liter groups suggests a physically larger transmission housing or hydraulic reservoir in the mid-range variants.
  • The MXM175 PRO and MXM190 PRO carry the largest capacity in the lineup at 100 liters. A 100-liter combined sump is consistent with the heavier Powershift transmissions typically found in higher-horsepower agricultural tractors, where greater hydraulic flow demands require additional fluid volume.
  • All six model variants across the 2003-2007 production span are specified under normal use conditions. In fluid service contexts, a normal use designation generally refers to standard operating cycles without the accelerated contamination or thermal stress associated with severe-duty classifications.
  • The Powershift designation noted in each capacity entry refers to a fully power-shifted transmission, meaning gear changes occur under load without a manually operated clutch pedal. Powershift transmissions typically share their fluid with the tractor's hydraulic and steering circuits, which directly explains why the capacity values are measured in tens of liters rather than the smaller volumes seen in dedicated steering reservoirs.
  • Capacity steps across the MXM PRO range follow a clear three-tier pattern: 80 liters for the MXM120 and MXM130, 90 liters for the MXM140 and MXM155, and 100 liters for the MXM175 and MXM190. Each tier pairs two consecutive model numbers, suggesting the lineup was built around three distinct driveline platforms rather than six unique configurations.
