Mud Cat 225D
Diesel Auger Dredge
This model is the longest-lasting auger dredge in the industry. The MC 225D is a one-truck transportable dredge 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 with two cutterbars for dredging in various environments including the SolidsMaster® cutter bar for breaking up sand and other harder materials and the EnviroMaster® for conveying sludges at higher solids to the pump intake. The MC 225D also includes the patented Pump Defender for reducing downtime in debris rich environments by up to 80%.Additionally, the Mud Cat 225D has a standard anti-corrosion package with 316 stainless steel hydraulic fittings and hardware as well as a ladder with downforce cylinders for pushing the cutter into harder layers to maximize solids. The dredge cuts an even bottom profile down to a max depth of 20 ft. (6.0m). The 230 HP (172kW) engine powers a 2,000 GPM (453m3/hr.) hi-chrome slurry pump with up to 120 ft. (36.6m) head. Like all Mud Cat D-Series dredges, the MC 225D can be equipped with the patented WeedMaster Cutterhead® that converts it to a hydraulic weed harvesting machine that can pump vegetation thousands of feet to shore, something no other dredge can do.
Remote Control Option
All Mud Cat D-Series models can be outfitted with a shoulder mounted radio remote control so the operator can operate the dredge functions from shore. This is ideal in high H2S (hydrogen sulfide) and contaminated environments where it is not safe to have an operator on board. Adding Mud Cat’s Radio Sense™ radio remote control with digital depth gauge is less than $12,000.

Features & 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 System: 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.
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%.
Dredging Depth: 20 ft. (6.1m) standard dredging depth making it the deepest digging in its class.
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.

1. This represents total flow capabilities of the pump – water and solids.
2. This represents theoretical maximum solids production. This is calculated based on 25% solids by volume and 1 complete hour cutting and pumping material. This estimate does not take into account material properties, time used for positioning, pumping distance or elevation. Buyer should consult Mud Cat for production estimates based specifically around their application.
