Kubota M series

Power steering fluid capacity & service interval

Kubota M series power steering fluid has a capacity range of 0,5 to 33 liters. Service intervals include checking at 10 and 400 hours, and changing at 400 and 600 hours. The data covers 13 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Across the M4500, M5500, and M7500 configurations, the power steering system holds 2 liters regardless of whether the tractor is a standard or DT (dual traction, four-wheel drive) variant. A 2-liter capacity is typical for a dedicated hydraulic power steering reservoir in tractors of this class, representing a service fill volume rather than a full system overhaul quantity.
  • Each of those same configurations carries a separate steering box with a capacity of 0.5 liters. The steering box is a mechanical gearbox that translates steering input, and at half a liter, the specification reflects a small enclosed gear cavity rather than a pressurized hydraulic circuit.
  • The power steering fluid on the M4500, M5500, and M7500 models is scheduled for a full change at 400 hours under normal use conditions. The 400-hour interval is a common benchmark in agricultural equipment servicing, roughly corresponding to a seasonal or annual threshold depending on operational intensity.
  • The steering box on the M4500, M5500, and M7500 is listed for a check at 400 hours rather than a fluid change. A check interval, as opposed to a change interval, indicates the service action is inspection and top-up if needed, not a scheduled drain-and-refill procedure.
  • The Kubota M series M4500 is paired with the S2600-A engine, the M5500 with the D3000-A, and the M7500 with the V4000-A. Despite the differences in engine displacement and configuration across these three models, the power steering capacity and service interval remain identical at 2 liters and 400 hours.
  • The Kubota M M7500 uses the V4000-A, a four-cylinder engine, while the M5500 uses the D3000-A, also a four-cylinder, and the M4500 uses the S2600-A, a three-cylinder unit. The steering system specifications show no variation tied to these engine differences.
  • The ME8200DTN, covering the 1997-2005 period, uses a combined transaxle, hydraulic system, and power steering circuit with a total capacity of 33 liters. This integrated design is substantially different from the separate power steering and steering box arrangement on the M4500, M5500, and M7500, where the two systems together total only 2.5 liters.
  • The ME8200DTN shared system carries a first check at 10 hours under normal use conditions. A 10-hour initial check is standard practice for new or freshly serviced equipment, allowing early detection of leaks or fluid contamination before the system reaches its regular service interval.
  • Following the 10-hour check, the ME8200DTN system is scheduled for a full fluid change at 600 hours under normal use conditions. The 600-hour change interval is longer than the 400-hour interval specified for the M4500, M5500, and M7500 power steering systems.
