County All models

Coolant capacity & service interval

County All models use coolant with a capacity range of 12,8 to 23,2 liters. Service intervals include checks every 10 hours and changes every 1200 hours or 12 months. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The County 1484 carries the largest cooling system capacity across the listed models at 23.2 liters, while the 1474 sits just below at 22.2 liters and the 1184 TW at 21 liters, reflecting the stepped displacement differences between these three larger-engined variants.
  • The County 762H holds a cooling system capacity of 12.8 liters, the smallest figure in the group, consistent with a smaller engine requiring less coolant volume to maintain operating temperature.
  • The 774 and 974 share an identical cooling system capacity of 18.8 liters despite being distinct models, indicating that both use engine configurations with equivalent thermal management requirements.
  • A 10-hour check interval applies uniformly across all six models under normal use conditions. In agricultural equipment, such a short inspection cycle reflects the high thermal and mechanical loads placed on cooling systems during continuous field operation.
  • The coolant change interval of 1200 hours or 12 months, whichever comes first, applies to all listed models under normal use. The dual threshold accounts for both high-use machines that accumulate hours quickly and lower-use machines where calendar-based fluid degradation becomes the limiting factor.
  • All six models share the same 1200-hour or 12-month change interval regardless of their differing capacities, meaning the service schedule is consistent across the range from the 12.8-liter 762H to the 23.2-liter 1484.
