Additional Notes

  • The Ditch Witch 410SX limited slip differentials, both front and rear, carry a fluid capacity of 2.1 liters per unit, regardless of whether the machine is fitted with the Deutz D2009 L04 Tier 4i or the Kubota WG1605-G-E3 engine.
  • The 420SX with the Deutz F3L2011 engine specifies a notably larger limited slip differential capacity of 4.7 liters, applying equally to both the front and rear differentials.
  • The capacity difference between the 410SX and 420SX differentials is substantial, with the 420SX units holding more than twice the fluid volume of the 410SX units, reflecting a physically larger differential assembly in the bigger machine.
  • Across all six configurations listed, the check interval for differential fluid is set at 500 hours under normal use conditions, indicating a mid-cycle inspection point before the full drain-and-fill service is due.
  • The change interval for all listed configurations is 1000 hours under normal use conditions, meaning fluid replacement is scheduled at twice the frequency of the check interval.
  • The front and rear limited slip differentials on each model share identical capacity and service interval specifications, so no distinction in service scheduling is needed between the two axle positions on a given machine.
