Additional Notes

  • The McCormick X4 Series front differential fluid capacity is 7.5 liters across all listed variants, from the X4.20 through the X4.70. In a front axle differential housing that also contains integrated brakes, a 7.5-liter fill volume reflects the additional fluid demand of wet-brake components sharing the same oil bath as the differential gears.
  • The front differential on all listed X4 Series configurations is specific to 4x4 drivetrains. The notation "with brakes" indicates a wet-brake axle design, where the braking elements are immersed in the differential fluid rather than operating as dry external components.
  • The service interval for all listed configurations is 1,000 hours or 12 months, whichever comes first. The dual-trigger structure, combining an operating-hour threshold with a calendar limit, accounts for tractors that accumulate hours slowly and would otherwise go extended calendar periods between fluid changes.
  • All front differential fluid intervals in the specifications are classified under normal use conditions. A normal-use classification in agricultural equipment typically reflects standard field and road operation, as opposed to severe-duty classifications that would apply to sustained heavy draft loads or extreme environmental exposure.
  • The X4 Series spans multiple engine families across the 2017-2022 model range. Deutz engines appear in Tier 4 Final (T4f) and Tier 4 Interim (T4i) emissions configurations, while the X4.35 uses a Perkins 1104D-44 engine rated to Tier 3. Despite the variation in engine supplier and emissions tier, the front differential fluid capacity and change interval remain identical across all configurations.
  • The X4.50 is the only model in the listed specifications paired with two distinct engine options: the Deutz C4DT58 in T4f configuration and the Deutz C4DT62 in T4i configuration. Both share the same 7.5-liter front differential capacity and 1,000-hour/12-month service interval, indicating the front axle assembly is common between the two engine variants on that model.
