Stone has added a 21-cubic-foot mortar buggy to the Stone Mud Buggy line – the SB2100. The mud buggy has a load capacity of 3,200 pounds with the versatility of a walk-behind or ride-on machine and is powered by a 13-hp Honda engine. It easily moves concrete, mortar, gravel, dirt, debris and more around the toughest jobsites. The new model has many of the same patented features of the 16-cubic-foot SB1600 buggy including: the one-piece, lift-away polyethylene engine cover requires no tools to remove and can be lifted away for full access to the engine compartment without dumping the tub; the patented lockable, fold-up operator platform is contoured, allowing increased maneuverability in confined areas; a large eight-gallon fuel tank provides longer run times while the seven-gallon removable hydraulic tank allows for cooler running; handlebar-mounted levers control speed and direction; a dumping lever and integrated foot pedal provide for precise, controlled dumping; heavy-duty foam-filled dual tires provide optimum maneuverability on most any terrain.
