Marsh Equipment Better by Design

Amphibious Excavators, Cargo Carriers, Slide Pontoons and other Marsh Equipment do heavy work in challenging terrain that is too obstructed for boats and barges but too soft for regular equipment.

Designed to be better balanced, more durable, and easier to maneuver, our machines help you to get the job done as quickly and safely as possible.

High quality, fully serviced, used machines are also available at a great price.

Amphibious Excavators

Amphibious Excavators are the workhorses that enable you to do heavy work in soft, waterlogged, and unstable terrain. Because they are designed to be durable, maneuverable and well balanced, our machines allow you to work efficiently to reduce transportation and operating costs.

Cargo Carriers

Fast and maneuverable, the low ground pressure Cargo Buggy is the perfect tool for getting people and material in and out of swamps, marshes, and boggy terrain.  A loading platform, safety rails and winching capabilities are just some of the features of these versatile support machines.

Slide Pontoons

Slide Pontoons are great tools for hauling equipment, debris and material in or out of marshes. They are particularly useful in very low viscosity situations. Combined with the winching capabilities of our cargo buggies you can do jobs that are inaccessible to other equipment.

Patent-pending Amphibious Excavator reduces transportation costs without compromising performance. 11’10” wide when retracted for transportation which means that it does not require an escort in most states. The pontoons then hydraulically expand to to 13’10” for normal operation.
