Do you need to create trenches for electrical, water, gas and fiber optic lines? FAE offers two wheel saw options to meet your trenching needs. Thanks to its modular-width disc rotor and a working depth of up to 20 inches, the RWM/SSL asphalt shredder excavates surfaces with extreme precision to create 3-, 4- or 5-inch-wide trenches. The RWL/SSL works down to a depth of 14 inches, for 1, 1.5 or 2 inch wide trenches.
