Making the Impassable Possible.

MM-1LX Amphibious Personnel Carrier


The amphibious MM-1LX is the smallest of the Marsh Master models. It is the flagship model that was first introduced back in 1980, when Coast Machinery started production of the Marsh Master. A success from the start, the basic design, with slight improvement and refinement, has remained the same, making it the most reliable and capable amphibious vehicle on the market today.
Small and nimble, its light weight, low ground pressure characteristics make it very popular with customers that require a personnel carrier capable of transporting one to five people through marsh and swamp. Capable of floating 1500 lb, it is a real workhorse in a small package. Its compact size allows the machine to be towed by a 1/2 ton pickup truck.
The MM-1LX marsh buggy is presently being used by electric utility companies, contractors, surveyors, environmental companies, oil and gas companies, and municipal/government agencies simply because it can go through terrains that limit or stop other track type or wheel type vehicles. It is simple to operate, very low maintenance and extremely reliable, making the MM-1LX an excellent cost effective solution for your wetland transportation needs.
