"Donald Andersen of the Wetland Habitat and Mosquito Management program of DEEP's Wildlife Division uses a Marsh Master amphibious mowing machine to cut down phragmites in a marsh in Stonington, CT, on Tuesday morning March 24, 2015. The phragmites abatement program for the wetland is scheduled for a multiple year program to rid the marsh land of the invasive plant." (credit)

Anyone ever see these things before? It's basically an amphibious tank. Show me some other badass ways to cut grass.
