Additional Notes

  • All MF 6S transaxle automatic transmission fluid specifications are rated for normal use conditions, and the 1800-hour change interval applies uniformly across every listed variant and transmission type.
  • The Massey Ferguson MF 6S Dyna-6 transaxle carries a capacity range of 56 to 70 liters. A range rather than a fixed value typically reflects variation between a drain-and-fill service quantity and a full overhaul or dry-fill quantity.
  • Dyna-VT variants across all MF 6S power ratings list a fixed transaxle capacity of 48 liters, a notably lower figure than the 56-to-70-liter range specified for Dyna-6 units, reflecting the different internal architecture of a continuously variable transmission versus a six-step powershift unit.
  • Dyna-VT configurations carry a separate 100-liter capacity entry designated for auxiliary hydraulics. In agricultural tractors, auxiliary hydraulic systems serve rear and mid-mounted implement circuits and are often integrated with the transmission housing, which accounts for the separate fluid volume specification.
  • When the auxiliary hydraulics capacity of 100 liters is considered alongside the 48-liter transaxle figure, the total fluid volume associated with Dyna-VT configurations reaches 148 liters, substantially exceeding the maximum 70-liter figure listed for Dyna-6 units.
  • The Dyna-VT specifications are associated with the 2021-2022 period, while Dyna-6 specifications begin from 2022, meaning both transmission types share the 2022 model year across all five MF 6S power variants: the 135, 145, 155, 165, and 180.
  • The 1800-hour service interval is consistent across both transmission types and all power variants. In agricultural equipment, hours-based intervals are standard because annual operating time varies widely depending on farm size and seasonal workload, making mileage or calendar-based intervals impractical.
