Deutz-Fahr Series 6 C

Additional Notes

• All six configurations of the Deutz-Fahr Series 6 C covered here share a uniform hydraulic brake system capacity of 1 liter, applying to the 6115C, 6125C, and 6135C variants under Stage 5 emissions compliance from 2022 onward.
• A 1-liter capacity for a hydraulic brake system is consistent with a sealed, relatively compact circuit typical of agricultural tractor brake assemblies, where fluid volume requirements are lower than in larger open hydraulic systems.
• The change interval across all six configurations is specified at 24 hours of operation under normal use conditions. In agricultural equipment, hour-based service intervals reflect the variable and often intensive nature of field work, where calendar-based intervals would be less meaningful.
• Each configuration is identified by a unique serial number threshold, distinguishing between two production lines per model variant. The 6115C, 6125C, and 6135C each carry one ZKDGV-prefixed and one ZKDLW-prefixed serial range, yet both lines within each model share identical brake fluid capacity and change interval specifications.
• The ZKDGV and ZKDLW serial prefixes likely denote different assembly or regional variants within the same power class, a common practice in tractor manufacturing where the same mechanical specification applies across multiple production identifiers.
• Stage 5 refers to the European Union's Stage V non-road mobile machinery emissions standard, which sets strict limits on particulate and nitrogen oxide output. The designation appears consistently across all six rows, indicating all covered units fall under this regulatory tier from the 2022 starting serial numbers onward.
