Mud Cat 275D – Diesel Dredge

The MC 275D – is the flagship of the Mud Cat diesel dredge product line designed to beat every global competitor on every vital performance spec. The MC 275D has a class winning state-of-the-art climate-controlled cab with dual 10-inch IQAN displays for instrumentation and back-up camera display, joystick controls, jump seat (for deckhand), and LED lights.

The system is one truck transportable and comes standard with a powerful cable drive system as well as a robust dual marine prop drive system for transport down waterways and self-propelled dredging.  The 275D boasts a powerful 300 HP (224 kW) diesel engine that powers a hi-chrome 3,000 GPM



  • Nominal Capacity – 3,000GPM (681 m³/hr) against 120 ft (36.6 m) head. Up to 267 yds³/hr (204 m³/hr) of production at 30% solids content. Results may vary.
  • Digging Depth – 7.6 m (25′)
  • Total Installed Power – 224 kW (300 HP)
  • Dry Weight – 15,400 kg (34,000 lbs)
  • Discharge – 205 mm (8″)

Features & Benefits

Superior Pump Design

8 in. (203 mm) x 10 in. (254 mm) hard iron 500 BHN pump for minimal ware in abrasive slurries.

High Solids Impellers

Standard impeller passes 6 in (152 mm) spherical solids. Optional HS impeller handles 8 in (203 mm) spherical solids.

Versatile Propulsion

Cable Drive: for use in sand and other consolidated materials where positive line-pull is ideal. Cable drive is also recommended in currents and windy conditions.
Dual Marine Prop Drive: for use in light silts and sludges in calm water environments. Ideal for larger lakes where cabling can be difficult. GPS system is beneficial when using prop drive.

Powerful Cutterhead

23,885 in-lbs torque for superior excavation.

Dredging Depth

25 ft. (7.6 m) standard dredging depth allows for greater project versatility.

Modern Operator’s Cab

Spacious, climate-controlled operators cabin with electronic over hydraulic controls, rear back up camera, digital depth gauge, CANbus system for easy troubleshooting with a factory, jump seat for deckhand/trainer, and electrical outlet.

Pump Defender (patent pending)

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%

One Truck Transportable

Ships on one truck fully assembled. Dredge fits on a 40 ft. flat rack with cutterhead and marine props removed. Reduces ocean freight and insures proper quality control over dredges that are completely disassembled.

Vegetation Cutterhead

Optional WeedMaster cutterhead converts the MC-275D into a hydraulic weed harvesting system that will cut hyacinths, reeds, and other types of vegetation into small pieces and pump them up to 3,280 ft. (1 km) away (includes open impeller pump option).

Optional Equipment

  • Optional debris impeller for up to 8 in. (203mm) solids passage
  • WeedMaster Cutterhead (patented) to convert to weed harvester
  • Radio remote control for operation in hazardous environments
  • Slurry sample line w/ on/off switch in the cab
  • Flow meter
  • Density Meter
  • GPS
  • Liner protection wheels
