Additional Notes

  • All six variants in the Massey Ferguson MF 9S lineup covered by these specifications share an identical transaxle automatic transmission fluid capacity of 67 liters, from the MF 9S.285 through to the MF 9S.425.
  • A 67-liter transaxle capacity is a substantial fluid volume, consistent with the large integrated transmission and axle housings found in high-horsepower agricultural tractors, where the transaxle serves both power transfer and hydraulic functions within a single shared sump.
  • The fluid level check interval is set at 50 hours under normal use conditions, a relatively short interval that reflects the importance of early detection of fluid loss or contamination in a high-load transaxle system.
  • The fluid change interval is specified at 1500 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger format means time-based degradation is accounted for even in low-utilization applications where the hour threshold may not be reached within two years.
  • The MF 9S.285, MF 9S.310, MF 9S.340, MF 9S.370, MF 9S.400, and MF 9S.425 all carry the same check, change, and capacity figures, indicating no variation in transaxle fluid specifications across the power variants of the 2023 MF 9S range.
