Mud Cat 115D – Diesel Dredge

The MC 115D – was designed around the premise of making a durable, productive, transportable, stable, safe, and affordable dredge for entry-level buyers or operations on a budget.  The controls can be learned quickly, and maintenance is simple. The system boasts a powerful 125 HP (93 kW) diesel engine, 2,000 GPM (454m3/hr.) dredge pump, and a powerful cutterhead with the patented Pump Defender for reducing downtime in debris rich environments by up to 80%.

The MC 115D has options for the patented WeedMaster Cutterhead that convert it to a hydraulic weed harvesting machine that can pump vegetation to shore as well as optional outboard motors for self-propulsion in non-compact materials.  The 115D also offers an optional radio remote control for additional versatility in toxic environments where safety is paramount.

  • Digging Depth – 4.6 m (15′)
  • Total Installed Power – 93 kW (125 HP)
  • Dry Weight – 7,257 kg (16,000 lbs.)
  • Discharge – 203 mm (8″) Low-Pressure Pump

Features & Benefits

Superior Pump Design

8 in. (203 mm) Ladder mounted pump for up to 5% higher solids. Lightweight and easy to fix with simple hand tools. No complicated seals or special tooling. Low Pressure (LP) pump is ideal for filling geotextile containers.

High Solids Pump

Passes 3.6 in. (91 mm) spherical solids with closed impeller and 4.3 in. (109 mm) spherical solids with open impeller for less clogging.

Versatile Propulsion

Standard cable drive propulsion for precision dredging and positive line pull or optional dual outboards for maneuvering into boat slips

Dredging Depth

15 ft. (4.57 m) standard dredging depth, making it the deepest digging in its class.

Versatile Control Station

Easy to use fingertip controls that can be learned in a few hours. Optional radio remote control feature.

Pump Defender (Patent-pending)

Patent-pending 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%.


Lightweight design is one truck transportable. The ultra-stable 115D fits in 2 x 40 ft. open top containers making it highly transportable and cost-effective for overseas shipments. The dredge is one centerpiece (all mechanical equipment) and two side tanks. This unit is highly transportable without compromising stability and operator safety

Vegetation Cutterhead

Optional WeedMaster cutterhead converts the MC 115D into a hydraulic weed harvesting system that will cut hyacinths, reeds, and other types of vegetation into small pieces and pump them to a remote discharge site (requires open impeller).

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 still leads the industry in technology, quality, and support. All designs use the highest quality components that are fully integrated into the dredge system. The MC115D is the most advanced auger dredge in the world.
