Additional Notes

  • All nine configurations of the Deutz-Fahr Series 4 EF share an identical transmission/transaxle fluid capacity of 35.5 liters. In agricultural machinery, a capacity at this level reflects a large integrated transmission and transaxle assembly, where the fluid serves both hydraulic and lubrication functions within a single shared sump.
  • Each configuration carries a fluid level check interval of 300 operating hours. On agricultural equipment, hour-based intervals are standard because seasonal and variable-load operation makes calendar time alone an unreliable measure of actual wear and fluid degradation.
  • The fluid change interval is set at 1,200 hours or 12 months, whichever comes first. The dual-trigger structure means that even machines with low annual hours are subject to a time-based change, accounting for fluid oxidation and additive breakdown that occurs independently of operational load.
  • All specifications apply under normal use conditions. In agricultural equipment service documentation, normal use typically refers to standard field operation as opposed to sustained extreme loads, high-dust environments, or other conditions that would otherwise shorten service intervals.
  • The Series 4 EF lineup covered by these specifications spans six distinct model designations: the 4055 EF, 4065 EF, 4075 EF, 4090 EF, and 4100 EF. Despite differences in power output implied by the model numbering, the transmission fluid capacity and service intervals are uniform across all of them.
  • Several model designations appear with two separate serial number prefixes, specifically the 4065 EF, 4075 EF, 4090 EF, and 4100 EF. The differing prefixes indicate distinct production variants or manufacturing lines, yet both variants within each model share the same 35.5-liter capacity and identical check and change intervals.
  • All configurations listed are Stage 5 emissions-compliant variants, with serial number ranges beginning from 2021. Stage 5 refers to the European Union's non-road mobile machinery emissions standard, which sets strict limits on particulate matter and other exhaust outputs for off-highway engines.
