Mud Cat 225D – Diesel Dredge

The MC 225D– is the longest-lasting auger dredge in the industry. The MC 225D is a one-truck transportable that has completed more industrial, agricultural, mining, and stormwater pond projects around the world than any other diesel dredging system.  The MC 225D is utilized by the leading environmental contractors around the globe.

The easy to use controls are stationed in a comfortable climate-controlled operator’s cabin.  The MC 225D comes in two cutterhead configurations.  The 815 Cutter is a higher torque designed for consolidated materials, and the 727 Cutter is a high shroud design for maximum solids intake.  The 230 HP (172kW) engine powers a 2,000 GPM (453m3/hr.) hi-chrome slurry pump with up to 120 ft. (36.6m) head.



  • Nominal Pump Capacity – 2000 GPM (453 m³/hr) against 120 ft (36.6 m) head. Up to 124 yd³s /hr (95 m³/hr) of production at 30% solids content
  • Digging Depth – 4.6 m (15′)
  • Total Installed Power – 168 kW (225 HP)
  • Dry Weight – 10,205 kg ( 222,500 lbs)
  • Discharge – 152 mm (6″) High-Pressure Pump

Features and Benefits

Anti-Corrosion Package 

Stainless steel hydraulic fittings, hydraulic lines, hardware, salt water coatings & sacrificial zinc anodes.

Superior Pump Design

Ladder mounted hi-chrome pump for higher solids and longer life in abrasive materials.

High Solids Pump

Passes 6 in. (152mm) spherical solids with recessed impeller for less clogging.

Adjustable Cutterhead

Low turbidity shrouded cutterhead with adjustable angle for maximum solids concentration.

Traverse Cable Drive

Allows dredge to be pulled at high torque into materials for high solids concentration. Cable system is overhead and not a tripping hazard.

SolidsMaster Cutterbar®

Standard aggressive cutterbar for sand and other dense materials.

EnviroMaster CutterbarTM

Standard cutterbar for conveying viscous slurries to the pump w/minimal disturbance & maximum solids.

WeedMaster Cutterhead®

Optional patented cutterhead converts the MC 225D into a hydraulic weed harvesting system that cuts hyacinths, reeds, and other types of vegetation into small pieces and pumps them to a remote discharge site. Quick disconnect hydraulics make the change simple.

Dredging Depth

20 ft. (6.1m) standard dredging depth making it the deepest digging in its class.

Pump Defender®

Standard patented Pump Defender allows for cleaning of the pump inlet after every revolution of the cutterhead to greatly reduce down-time in debris rich environments by up to 80%.

Slurry Sample Line “Tattle Tail”

The standard Slurry Sample line allows the operator to see what they are pumping in real time and to make adjustments to the process to maximize solids and pumping efficiency.

Transportability & Launching

Dredge is one truck transportable & ships on a standard 40 ft. flat rack for export. Includes 2 lifting points on Starboard and 2 lift points on Port to accommodate a 4-point lift harness when launching by crane.

Mud Cat Engineered

Designed by Mud Cat’s expert group of engineers and made in the USA from 100% USA content. Mud Cat invented the auger dredge and the MC 225D is the basis for the entire auger dredge industry.
