McCormick S-Max

Additional Notes

• The McCormick S-Max power steering system holds a uniform 2.5-liter capacity across all six configurations listed, spanning the S45, S50, S60, S75, and S90 variants introduced from 2019.
• A 2.5-liter power steering fluid capacity is consistent with a mid-range hydraulic reservoir volume, typical of tractors in this segment where the steering circuit is a dedicated closed loop rather than shared with the implement hydraulics.
• All six configurations carry a normal use condition designation, meaning the specified 2.5-liter capacity applies under standard operating demands rather than elevated-stress or severe-duty cycles.
• The S60 grade appears in two distinct configurations, the ITL 3100 FLT and the ITL 4100 FL, both introduced from 2019 and both sharing the same 2.5-liter power steering capacity despite differing drivetrain codes.
• The ITL codes across the lineup reflect different engine and transmission pairings, yet the power steering fluid capacity remains unchanged at 2.5 liters regardless of whether the unit carries a three-cylinder or four-cylinder designation within the code.
• The S75 and S90 variants, designated ITL 4100 FLT/ELT and ITL 4105 FLT/ELT respectively, represent the higher-output configurations in the listed range and still share the same 2.5-liter steering fluid volume as the lower-rated S45 and S50 models.
