Additional Notes

  • The Kubota M series M7-131, M7-151, and M7-171 powershift transmissions each carry an 85-liter fluid capacity, a volume consistent with large agricultural tractor powershift units where the transmission also serves as a hydraulic reservoir shared across multiple drivetrain functions.
  • The M7-132, M7-152, and M7-172 models introduced in 2018 share the same 85-liter powershift transmission capacity as the earlier M7-131, M7-151, and M7-171 variants, indicating no change to the transmission housing or sump design between those model generations.
  • Under normal use conditions, the M7-131, M7-151, and M7-171 powershift transmissions follow a 1000-hour fluid change interval, a figure typical of heavy-duty agricultural equipment where extended drain periods reduce downtime during seasonal operations.
  • A first-change-only interval of 500 hours applies to the M7-131, M7-151, and M7-171 powershift transmissions. A shortened initial service interval is standard practice for new mechanical assemblies, as early operation generates elevated levels of metal particles and manufacturing residues that accelerate fluid contamination.
  • The M7-132, M7-152, and M7-172 models carry only a normal-use 1000-hour interval in the specifications, with no first-change-only entry listed, unlike the corresponding M7-131, M7-151, and M7-171 variants.
  • Across all nine specification rows, the 85-liter figure represents a service fill capacity rather than a dry or overhaul fill. Service fill values account for fluid retained in internal passages, coolers, and torque converter circuits that does not drain during a standard fluid change.
