Additional Notes

  • The Ursus 32/34 series cooling system capacities fall into two groups across the lineup. The 832, 832 4WD, 932, 934, 1032, 1034, 1132, and 1134 models all share a 23-liter capacity, while the 1232, 1234, 1434, and 1634 models require 25 liters.
  • The 2-liter difference between the two capacity groups reflects the larger engine displacement found in the higher-numbered models of the 32/34 series, which typically corresponds to a greater coolant jacket volume around the engine block and cylinder head.
  • All variants across the 32/34 series carry a uniform coolant change interval of 24 months under normal use conditions, regardless of whether the capacity is 23 or 25 liters.
  • A 24-month coolant change interval is a time-based service schedule rather than a mileage or hours-based one, which is common for agricultural tractors where annual operating hours can vary considerably between seasons and farm operations.
  • The 832 and 932 sub-series are each available in both 2WD and 4WD configurations, with the 4WD variants designated by the numeral 4 in the model suffix, yet both drivetrain variants within each sub-series share identical 23-liter cooling system capacities.
  • The 1032/1034 and 1132/1134 pairings similarly show no capacity difference between 2WD and 4WD configurations, confirming that drivetrain type does not influence cooling system volume within the same engine family.
  • The 1434 and 1634 models are listed exclusively as 4WD variants, and both share the 25-liter cooling system capacity seen in the 1232/1234 range, placing them in the same upper capacity tier of the series.
  • All specifications across the 32/34 series are listed under normal use conditions, meaning the 24-month interval and stated capacities apply to standard operating environments rather than severe-duty or high-load applications.
