Stone Construction Equipment has added a 21-cubic-foot mortar buggy to the Stone Mud Buggy line — the SB2100. The new model 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. The SB2100 is designed to move concrete, mortar, gravel, dirt and debris around jobsites. 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. A large 8-gallon fuel tank provides longer run times while the 7-gallon removable hydraulic tank allows for cooler running.
