The S-840 is a four-wheel, ride-on small laser screed. It allows contractors to exceed standard flatness and levelness at higher productivity rates—up to 5,000 sq. ft./hr. Offset auger head design allows for one-man operation, no rakers needed. Better equipment utilization: three head options in both 6- and 8-ft. widths—raking, subbase, and screed heads for better equipment utilization. 3D Profiler System compatible.
