Additional Notes

  • The power steering fluid specification for the LS Tractor XR Series covers a shared reservoir that also serves the transaxle and hydraulic system, meaning the listed capacity reflects the entire combined fluid volume rather than a dedicated power steering reservoir alone.
  • XR3032/C, XR3037/C, XR3135, and XR3140 models all carry a 30-liter capacity for the combined transaxle, hydraulic, and power steering system, placing them in the lower capacity group within the XR Series.
  • XR4040/C, XR4046/C, XR4140, XR4145, XR4150, and XR4155 models share a 43-liter capacity for the same combined system, a volume 13 liters greater than the XR3000-range models, consistent with the larger frame and higher horsepower class of the XR4000 range.
  • The 43-liter figure across all six XR4000-range variants indicates a uniform reservoir design within that sub-series, regardless of whether the model designation ends in /C or not.
  • A 50-hour check interval applies across all ten models under normal use conditions. In tractor service, a 50-hour interval is a relatively short inspection cycle, reflecting the importance of monitoring fluid level in a system shared across three functions.
  • The 500-hour change interval under normal use conditions is consistent across all XR Series models listed. On a tractor used in typical agricultural or grounds maintenance work, 500 hours represents a moderate service period that can span one or more seasons depending on annual usage.
  • The XR3135 and XR3140 have a starting year of 2017, while the XR3032/C and XR3037/C carry a starting year of 2013, meaning the two groups within the XR3000 range were introduced at different points despite sharing the same 30-liter capacity specification.
  • All XR4000-range models listed share a 2013 starting year, indicating the entire XR4000 sub-series entered production at the same time with a consistent 43-liter system capacity from the outset.
