Additional Notes

  • The Fendt 300 Vario S4 brake fluid system is classified as a pneumatic brake system across all listed variants, spanning the 309 through 313 model designations in both Power and Profi trim levels for 2015-2021.
  • A uniform brake fluid capacity of 0.5 liter applies to every variant in the specifications, covering all model numbers and both trim levels without exception.
  • Under normal use conditions, a fluid level check is required at every 10-hour interval. This short inspection cycle reflects the safety-critical nature of brake system integrity in heavy agricultural machinery.
  • The normal use change interval is set at 500 hours or 12 months, whichever comes first. The dual threshold means calendar time can trigger a change even when hour accumulation has not reached the 500-hour mark.
  • A separate first-change-only interval of 50 hours is specified for every variant. An early first change at 50 hours is a common practice in machinery to flush any residual contaminants or moisture introduced during assembly and initial operation.
  • The Power trim level carries the designation code suffix /23/ in the serial number structure, while the Profi trim level carries /21/. Both trims share identical capacity and interval values across all model numbers from 309 to 313.
  • The 309, 310, 311, 312, and 313 model numbers each represent distinct tractor variants within the S4 generation, yet the brake fluid specifications remain consistent across all five, with no variation in capacity, check frequency, or change intervals between them.
