Additional Notes

  • The Zetor Crystal cooling system capacity is 30 liters across all listed configurations, which is a substantial volume typical of large agricultural tractor cooling systems designed to manage heat from high-displacement engines under sustained load conditions.
  • The Crystal 150 and Crystal 160, both powered by the Deutz TCD6.1 L6, share an identical 30-liter cooling system capacity and a 24-month coolant change interval under normal use conditions.
  • The Crystal HD 150 and Crystal HD 170 variants, introduced from 2018, carry the same 30-liter capacity and 24-month change interval as the standard Crystal models, despite the HD designation indicating a heavier-duty specification.
  • A 24-month service interval for coolant, applied here under normal use conditions, reflects a time-based replacement schedule rather than a mileage or hours-based one, which is common in agricultural equipment where annual operating patterns vary widely.
  • All four configurations use the same Deutz TCD6.1 L6 engine, a six-cylinder turbocharged diesel unit, and the uniform 30-liter cooling capacity across the range suggests a shared cooling system architecture regardless of power output differences between the 150, 160, and 170 horsepower variants.
