Additional Notes

  • The Ursus Bison 200 series cooling systems carry notably large capacities, reflecting the scale of agricultural tractor engines designed for sustained heavy-duty field operation rather than light vehicle use.
  • The Bison 207, 208, 209, and 210 — available in both 2WD and 4WD configurations — share a uniform cooling system capacity of 23 liters, indicating a common engine block architecture across those four variants.
  • The Bison 212 4WD and Bison 214 4WD each carry a 25-liter cooling system capacity, 2 liters more than the lower-numbered variants, which points to a larger or more thermally demanding engine in those models.
  • All six variants in the Bison 200 series specify a 24-month coolant change interval under normal use conditions, meaning the interval applies to standard operating environments rather than extended high-stress or dusty field conditions.
  • The 212 and 214 are listed exclusively as 4WD configurations, whereas the 207, 208, 209, and 210 are each specified for both 2WD and 4WD, reflecting a broader drivetrain range in the lower-numbered models.
  • A 23-liter cooling system capacity is a substantial service fill volume, consistent with multi-cylinder diesel engines common in tractors of this class, where large coolant volumes help stabilize operating temperatures during prolonged load cycles.
  • All six models share a starting year of 1987, placing the entire Bison 200 series within the same production generation for cooling system specification purposes.
