Ursus Bison 200 series

Additional Notes

• The Ursus Bison 200 series power steering specifications cover a combined hydraulic system, meaning the listed capacity serves both the hydraulic system and power steering circuit together rather than power steering alone.
• The Bison 207, 208, 209, and 210 in both 2WD and 4WD configurations share an identical combined hydraulic and power steering capacity of 7 liters, indicating a common system architecture across those variants regardless of drivetrain.
• The Bison 212 4WD and Bison 214 4WD each carry a 10-liter capacity for the combined hydraulic and power steering system, a notable increase of 3 liters over the lower-numbered variants in the same series.
• The 10-liter figure on the 212 and 214 models is consistent with larger or more complex hydraulic circuits, which typically arise from higher-output hydraulic pumps, additional remote valve circuits, or greater system pressure demands in heavier-duty tractor configurations.
• All six variants share the same service interval structure: a fluid level check at every 200 operating hours and a full fluid change at every 400 operating hours, applied under normal use conditions.
• The 200-hour check interval is a standard precautionary measure in agricultural equipment, allowing early detection of fluid loss or contamination before the scheduled change point is reached.
• A 400-hour change interval is typical for tractor hydraulic systems operating under normal conditions, as opposed to severe-duty cycles that would generally call for shorter drain intervals.
• The availability of both 2WD and 4WD configurations on the 207 through 210 models, each with the same 7-liter capacity, suggests the power steering and hydraulic circuit volume was not altered to accommodate the additional front axle drive components on the 4WD variants of those models.
