Additional Notes

  • All six McCormick S-Max configurations listed — the S45, S50, S60 (both ITL 3100 FLT and ITL 4100 FL variants), S75, and S90 — share an identical cooling system capacity of 10 liters, indicating a uniform cooling circuit volume across the entire range despite differences in engine designation.
  • A 10-liter cooling system capacity is a moderate figure for compact-to-mid-range agricultural tractors, reflecting a system sized to manage heat from relatively small-displacement engines under sustained field operation rather than high-output heavy machinery.
  • The S60 model is the only variant in the range offered with two distinct engine options — the three-cylinder ITL 3100 FLT and the four-cylinder ITL 4100 FL — yet both share the same 10-liter cooling system capacity, pointing to a common cooling circuit design across those two engine families within that model.
  • The S75 and S90 entries each list dual transmission suffix variants (FLT/ELT), meaning the single 10-liter capacity figure applies across those transmission configurations without differentiation.
  • The coolant change interval for all listed configurations is 1000 hours or 12 months under normal use conditions, whichever comes first. The dual-trigger format is standard practice in agricultural equipment servicing, where seasonal or low-hour machines may reach the calendar threshold before the hour threshold.
  • The 1000-hour service interval for coolant is a common benchmark in tractor maintenance schedules, generally aligned with annual overhaul cycles for machines operating at typical seasonal workloads of several hundred hours per year.
  • All rows are designated for normal use conditions, meaning the 1000-hour/12-month interval reflects standard operating environments rather than extended-stress or severe-duty cycles, which would typically carry shorter drain intervals.
