Additional Notes

  • The Hürlimann XL.K 115, XL.K 125, and XL.K 135 all share an identical cooling system capacity of 15.5 liters, indicating a common engine cooling architecture across the three Stage 5 variants starting from serial numbers ZKDGW10200TH50001, ZKDGW20200TH50001, and ZKDGW30200TH50001 respectively.
  • A 15.5-liter coolant capacity is consistent with a mid-to-large agricultural tractor cooling circuit, where higher volumes help sustain thermal stability during extended field operations.
  • The coolant check interval is set at every 10 hours of operation under normal use conditions, which reflects a high-frequency monitoring requirement typical of heavy-duty machinery during early service or continuous-use periods.
  • The coolant change interval across all three variants is specified at 2400 hours or 24 months under normal use conditions, whichever comes first, meaning both an operational hour threshold and a calendar-based limit apply simultaneously.
  • A 2400-hour change interval is relatively extended for agricultural equipment, suggesting the specified coolant formulation is designed for long-life service rather than conventional short-cycle replacement.
  • The dual-condition change interval of 2400 hours or 24 months means a machine used in lower-intensity seasonal applications could reach the calendar limit well before accumulating sufficient operating hours, making the 24-month threshold the governing factor in such cases.
