Fendt Farmer 300 C
Differential fluid capacity & service interval
Fendt Farmer 300 C differential fluid capacity ranges from 6 to 7,5 liters. Service intervals include checks at 250 hours, 500 hours, or 12 months, and fluid changes at 1000 hours or 12 to 24 months. The data covers 9 configurations.

Additional Notes
- The Fendt Farmer 300 C front differential holds 6 liters across all 307 C, 308 C, and 309 C variants, regardless of serial number range or model year within the 1998-2001 production period.
- The 307 Ci, 308 Ci, and 309 Ci limited slip front differentials introduce a second capacity value tied to axle flange width. A 1660 mm flange corresponds to 6 liters, while a 1760 mm flange requires 7.5 liters, a 25 percent increase that reflects a physically larger differential housing.
- Within the 307 C, 308 C, and 309 C lines, serial numbers from 0001 to 5000 carry a fluid check interval of 250 hours under normal use conditions, paired with a change interval of 1000 hours or 24 months.
- From serial number 5001 onward on the same 307 C, 308 C, and 309 C models, the check interval doubles to 500 hours, while the change interval shortens to 1000 hours or 12 months. The more frequent time-based change threshold on later serial numbers means the fluid is replaced on a tighter calendar schedule despite the less frequent checks.
- The Ci variants from 2004-2008 align with the later serial number check interval of 500 hours but revert to the 24-month time-based change threshold seen on the earliest serial number range, combining the less frequent check schedule with the longer calendar-based drain interval.
- A 1000-hour operating threshold appears as the consistent hour-based change interval across all 307 C, 308 C, and 309 C variants and serial number ranges, indicating a uniform maximum service life for the differential fluid regardless of other interval differences.
- The limited slip designation on the Ci models is a mechanical distinction relevant to fluid selection, as limited slip differentials typically require lubricants with friction modifier additives that differ from standard gear oils used in open differentials.
