Additional Notes

  • The LSTractor R series power steering fluid specification covers a shared reservoir that also serves the transaxle and hydraulic system, meaning the listed capacity reflects the total volume of that combined circuit rather than a dedicated power steering reservoir alone.
  • The R3029, R3029H, R3039, and R3039H variants all carry a 30-liter capacity for the combined transaxle, hydraulic, and power steering system under normal use conditions.
  • The R4041/EZ, R4047/EZ, and R4047H variants carry a 43-liter capacity for the same combined system, a difference of 13 liters compared to the smaller R30-series variants.
  • A fluid level check interval of 50 hours applies uniformly across all seven variants listed, reflecting a routine inspection point rather than a drain-and-fill service.
  • A full fluid change interval of 600 hours applies uniformly across all seven variants under normal use conditions, representing the point at which the entire shared system volume is drained and refilled.
  • The H suffix designates hydrostatic transmission variants within the R series, yet the R3029H and R3039H share the same 30-liter capacity and identical check and change intervals as their non-hydrostatic counterparts.
  • The R4047H carries the same 43-liter capacity and 600-hour change interval as the R4047/EZ, indicating no difference in fluid service requirements between the hydrostatic and EZ variants at the R4047 size.
