Additional Notes
- The Deutz-Fahr Series 4 E Keyline front differential capacity splits into two distinct values across the model range: the 4046, 4050, and 4055 E Keyline each hold 5 liters, while the 4060 E Keyline holds 5.5 liters.
- The 0.5-liter difference between the 4060 E Keyline and the three lower models reflects a larger front differential housing, which is consistent with the higher-output engine variant requiring a more robust drivetrain assembly.
- All four models share an identical service interval of 1200 hours or 24 months under normal use conditions, whichever comes first, meaning time elapsed and operational hours are both active thresholds for scheduling a fluid change.
- The dual-trigger interval structure, combining an hourly limit with a calendar limit, accounts for tractors that accumulate hours slowly, ensuring fluid degradation from age alone does not go unaddressed even at low annual workloads.
- A 5-liter front differential capacity, as seen on the 4046, 4050, and 4055 E Keyline, is a moderate fill volume for a compact utility tractor front axle, consistent with a service refill rather than a full overhaul drain requiring disassembly.
- All specifications listed apply to normal use conditions, meaning the 1200-hour and 24-month intervals are not adjusted for severe-duty operation within the data provided for the 2019 Series 4 E Keyline range.
