Additional Notes

  • The Deutz-Fahr Series 4 E Keyline hydraulic brake system holds a capacity of 1 liter across the 4046, 4050, 4055, and 4060 variants, which is a figure consistent with a service fill rather than a full system overhaul volume.
  • The 50-hour check interval applies to normal use conditions across all four variants, meaning the brake fluid level is inspected at every 50 hours of operation under standard working demands.
  • A 50-hour interval is relatively short compared to many agricultural machinery service schedules, reflecting the safety-critical nature of hydraulic brake fluid monitoring in tractor applications.
  • The 1-liter capacity figure is uniform across the 4046, 4050, 4055, and 4060 E Keyline models, indicating no variation in brake system reservoir size between the different engine output configurations within the lineup.
  • The check interval is expressed in operating hours rather than calendar time, which is the standard method for agricultural equipment servicing where annual mileage or time in use can vary considerably between seasons.
