Additional Notes

  • The Toro Groundsmaster 4000-D, 4010-D, 4100-D, and 4110-D models all carry a rear differential fluid capacity of 2.4 liters, a figure consistent across both model number variants within each series (30448/30605, 30446/30603, 30449, and 30447 respectively).
  • The Groundsmaster 4500-D and 4700-D share the same 2.4-liter rear differential capacity as the earlier 4000-series models, indicating a uniform rear differential housing size across all six model lines covered in these specifications.
  • A first-change interval of 200 hours applies to all models listed. An early fluid change at this interval is standard practice for new or rebuilt differentials, as metal particles generated during initial component wear are removed before the fluid continues in regular service.
  • Under normal use conditions, the rear differential fluid change interval is set at 800 hours or 12 months, whichever comes first. The dual-trigger structure means time elapsed can mandate a change even when the hour threshold has not been reached.
  • A fluid level check at 400 hours is specified under normal use conditions for all models, placing the inspection interval at exactly the midpoint between the first-change and the standard change interval of 800 hours.
  • The 4000-D and 4010-D each appear under two separate model numbers (30448 and 30605 for the 4000-D; 30446 and 30603 for the 4010-D), with serial number ranges beginning at 312000001 and 313000001 respectively. Both variants within each pairing share identical differential capacity and interval specifications.
