Making the Impassable Possible.

The Marsh Master® Advantage

Decades of strong performance and dependable service have made the Marsh Master into a name that speaks for itself.


The Marsh Master is designed specifically for traversing wetland terrain. The following key features are what empower the Marsh Master to get your job done.

The engineering concept behind the Marsh Master is a rubber-belt track encircling pontoons with a flat bottom in between, connecting the two. By design, the tracks are ideally the only interface between the buggy and the environment. With nothing protruding underneath, this feature ensures that if anything such as stumps, logs, or other obstacles make contact with the bottom, the machine will glide over it without losing propulsion.When tracking in difficult marsh and swamp terrain, high ground clearance is critical for good performance. Swamp and marsh terrains seldom present optimal or predictable conditions, therefore high ground clearance helps cover all contingencies. It keeps the body from plowing through the terrain, which robs the machine of propulsion. Instead of forcing the body to plow through the terrain, it rides over it. The height gives the tracks more opportunity to maintain contact with the bottom, which increases traction. 32″ of ground clearance gives the Marsh Master the ability to run through heavy brush, thickets, or stumps without hanging up or high centering.
The Marsh Master’s pontoon chambers give it high flotation and freeboard. This combination is critical for performance and safety.From a performance standpoint, high flotation helps even when the tracks are touching bottom. The buoyancy of the pontoons helps to lift the machine, which makes it behave as though it were lighter. High flotation also allows the Marsh Master to carry extra weight such as extra men, equipment, and attachments. The ability to carry the extra load is crucial since most jobs require more than just getting one person to a site.

From a safety standpoint, high freeboard ensures that the buggy will not take in water over the sides. The Marsh Master is extremely stable in deep water where full flotation is required. Personnel can walk around the machine on the decks with no fear of compromising stability. High freeboard is also critical when transitioning from steep banks to water. As the Marsh Master enters the water, the pontoons give it the proper amount of buoyancy to counter the portion of the machine’s weight that is in the water. There is no need to worry about swamping the machine in deep holes or washouts. The Marsh Master has plenty of flotation when encountering these unforeseen obstacles in the swamp or marsh.

Low ground pressure is attributed to the lightweight nature of the Marsh Master and surface area of the track. As the picture to the left shows, the tracks essentially create a massive pad for the machine to run on. This pad evenly distributes the weight of the machine, which lightens its footprint. With a ground pressure of approximately 1 psi, the environmental impact is minimal. The photograph below was taken immediately after a Marsh Master tracked through these water hyacinths. Notice how there is hardly any evidence that it has even been there.In addition to environmental concern, the low ground pressure increases the mobility of the Marsh Master. The machine turns easier and tracks smoother. The video to the left demonstrates how the low ground pressure of the MM-1LX allows it to run on top of floating marsh instead of breaking through.

A track that extends beyond the body enables the Marsh Master to climb steep canal banks, cross deep ditches and track through heavy thickets with ease. As the video to the left demonstrates, the tracks engage the bank first when transitioning from water to land, pulling the machine up the bank. By design, the track system is the outermost part of the machine, giving it the ability to pull itself out of nearly any situation.A tall track with a 30° angle in the front and 45° angle in the rear of the Marsh Master is critical for good performance. These angles enable the tracks to generate a downward force on whatever objects they engage. This downward force provides more traction, allowing the Marsh Master to pull itself up and over most obstacles.

Simple… Rugged… Reliable…

The Marsh Master is a tough machine. It has to be because wetlands present some of the harshest environments for machinery. Everything is designed to keep you from getting stranded at the world’s end.

The hydrostatic drive is rugged, simple and safe. There are no clutches, brakes, gears, or chains to maintain or control. The main pump connects directly to the engine supplying flow to low speed, high torque final drives. The all-mechanical linkages make the machine very smooth and easy to operate, using only one hand. Ease of operation, excellent control-ability, and bullet-proof reliability ensure you and your crew make it back to the bank every time.
Unlike a molded rubber track, the Marsh Master track is a modular design that incorporates light weight, high strength aluminum track cleats, stainless steel bolts, rubber belts and wear resistant urethane drive lugs. The advantages of this design are many. the high strength aluminum cleats provide aggressive traction even in the worst conditions. All components of the track provide long-term maintenance free service. The stainless steel track bolts will not corrode, even in salt water, ensuring easy removal. Each component can be easily replaced if worn or damaged, and good components can be reused when belts eventually have to be changed.

1/8″ and 3/16″ marine grade aluminum unibody construction provides high strength, light weight, corrosion resistance, and years of trouble free service that customers expect and demand from our products. “The proof is in the pudding”- the first production Marsh Master, built in 1980, is still in use today.
The proprietary bogey system that supports the Marsh Master is the spine of the machine. It supports the weight of the machine while providing a smooth ride in soft terrain. Totally sealed and requiring no greasing, it is designed to run day in and day out in mud, sand, grit, and grime, and only with occasional maintenance. When service is required, the oil can be changed without removal from the machine, but the simple bolt-on design makes for easy removal if need be.
The Marsh Master incorporates a 10,000 lb front-mounted hydraulic winch. With no electric motor, switches, or solenoids to corrode or burn out, this winch provides reliable pulling power every time you need it.

Lagniappe…a little something extra

The Marsh Master has a transom for mounting a small outboard motor. You may find mounting an outboard motor to be advantageous when travelling a long distance over water or travelling in a heavy current. With a small tiller steer outboard motor, the Marsh Master will steer and maneuver like a boat.

The auxiliary hydraulic circuit makes the machine more than just a personnel carrier. Every machine comes standard with a 6-8 gpm circuit for running open center tools. The MM-2C-LX model is equipped with a standard tool circuit as well as a 25 gpm high flow circuit. Check out our MM-2LX Page for all of the hydraulic attachments that we offer for the Marsh Master.
Each Marsh Master has a cargo area in the rear of the buggy for hauling tools, containers, personnel or whatever else you may need.
