Rotary Ditcher

The DONDI DBR55A – 18° is a high-efficiency, dual-rotor central excavation rotary ditcher engineered for creating and maintaining drainage and irrigation channels. Operating at working depths from 55 to 70 cm with a narrow 18° wall angle, it shapes clean, stable trench profiles with uniform bottoms while evenly distributing excavated soil on both sides.

Description

Product Description

Designed for tractors requiring 60 to 70 HP, the DBR55A delivers reliable digging performance even in demanding, heavy soil conditions. Its double-wheel rotor system ensures rapid, consistent trenching while maintaining clean channel structures essential for long-term water management.

By spreading excavated earth evenly along both banks, it minimizes post-excavation cleanup and facilitates seamless soil integration across field edges.

 

Sugarcane Farming Applications

  • Waterlogging Prevention: Digs deep, narrow drainage trenches (up to 70 cm) to rapidly drain excess water during heavy rains or monsoon seasons, preventing root rot and safeguarding sucrose/Brix content.
  • Controlled Irrigation Setup: Easily carves out clean, uniform water distribution channels for flood or furrow irrigation systems across sugarcane blocks.
  • Headland & Border Drainage: Keeps field perimeters and haul roads well-drained so harvesters, grabbers, and loaded cane trucks do not get bogged down during wet harvesting periods.

 

Key Features & Benefits

  • Dual-Rotor Excavation System: Dual excavation rotors ensure high cutting efficiency and consistent trench geometry.
  • Bilateral Soil Discharge: Spreads dug soil evenly across both sides of the trench to maintain balanced ground height.
  • Narrow Trench Profile: The 18° wall angle creates stable, high-capacity channels that hold structural integrity over time.
