Additional Notes
- The McCormick X6 Series hydraulic brake system holds a capacity of 1 liter across the X6.420, X6.430, and X6.440 variants for the 2014-2021 model years.
- A 1-liter capacity in a hydraulic brake system is consistent with a sealed, closed-loop circuit typical of agricultural machinery, where fluid volume requirements are relatively modest compared to open hydraulic systems.
- All three variants, the X6.420, X6.430, and X6.440, share an identical 1-liter brake fluid capacity, indicating no variation in brake system volume across the power output range within the T4i / IIIB engine tier.
- The specifications apply under normal use conditions, meaning the 1-liter capacity figure is associated with standard operating environments rather than severe-duty or first-fill scenarios.
