Additional Notes

  • The Ditch Witch RT30 with Kubota D1105 Stage IV/Tier 4f engine carries 2.3 liters in the front differential and 2.6 liters in the rear, with both positions sharing a 10-hour check interval and a 600-hour change interval under normal use conditions.
  • The RT45 configurations, covering both the Deutz D2.9 L4 and the Deutz F3M2011 Tier 4i/EU Stage IIIa engines, list two distinct capacity values for both the front and rear differentials. The front differential shows either 2.3 or 2.8 liters, and the rear shows either 2.6 or 2.8 liters, reflecting variation likely tied to axle configuration or build variant within the same model designation.
  • Across all RT45 differential positions and both engine variants, the check interval is 500 hours and the change interval is 1,000 hours under normal use, doubling the change interval of the RT30.
  • The Ditch Witch RT55 with Deutz D2011 L04o Tier 4i/EU Stage IIIa engine applies an initial service change at 250 hours for both the front and rear differentials, each holding 4 liters. After that first service, the change interval extends to 1,000 hours under normal use conditions, with checks at 500 hours.
  • The RT80 with Deutz TD2011 L04w engine also carries an initial service change interval of 250 hours for the front differential, which holds 3.3 liters. The normal change interval is 1,000 hours, with no separate check interval listed for that position.
  • The rear differential/transmission on the RT80 Deutz TD2011 L04w lists two separate capacity figures depending on axle type: 7.1 liters for the steering axle configuration covering the differential and transmission together, and 10 liters for the rigid axle including wheel reductions. The 10-liter figure is among the largest single-position differential fluid capacities across all RT configurations in these specifications.
  • The initial service interval for the RT80 Deutz TD2011 L04w rear differential/transmission mirrors the front at 250 hours, applying equally to both the 7.1-liter steering axle and the 10-liter rigid axle variants before transitioning to the 1,000-hour normal change schedule.
  • The RT80 equipped with the Deutz TD3.6 L4 Tier 4f engine, introduced from 2015, carries 3.3 liters in the front differential with a 1,000-hour change interval and no listed check interval, while the rear differential holds a notably smaller 1.7 liters with a 250-hour check interval and a 1,000-hour change interval under normal use.
  • The rear differential capacity of 1.7 liters on the RT80 Deutz TD3.6 L4 Tier 4f is substantially lower than the rear differential figures on other RT80 configurations, where the TD2011 L04w rear assembly ranges from 7.1 to 10 liters depending on axle type.
