Additional Notes

  • The Yanmar YT2 series power steering fluid shares a unified reservoir with the transaxle and hydraulic system, meaning the 31-liter capacity figure reflects the combined fill volume for all three interconnected systems rather than a standalone power steering reservoir.
  • A 31-liter combined system capacity is notably large relative to typical consumer vehicle power steering circuits, which is consistent with the demands of tractor hydraulic systems that must support implement lift, steering assist, and transmission lubrication simultaneously.
  • The fluid check interval is set at every 10 operating hours under normal use conditions, a frequency that reflects the high-stress, variable-load environment of tractor operation where fluid contamination or level loss can occur more rapidly than in on-road vehicles.
  • The change interval is specified at 600 hours or 24 months under normal use conditions, whichever comes first, meaning calendar time can trigger a service requirement even when the hourly threshold has not been reached.
  • All five variants in the YT2 lineup covered by the 2021 specifications, the YT222, YT225, YT228, YT232, and YT235, share identical capacity and interval values, indicating no differentiation in fluid service requirements across the model range despite differences in engine output implied by the numeric suffixes.
