The RTx-SC2 trench roller comes standard with 32-inch drums with extensions that can be detached for conversion to a 22-inch machine width. Three bolts attach the extensions, resulting in a roller that can match a standard 3- and 2-foot excavator bucket, the company says. The unit has a raised mounting surface, integrated handles and supplemental bolts to protect the threads when the extensions are not in use and to avoid soil buildup and corrosion, according to the company. The RTx-SC2 offers a maintenance-free/lubrication oil-free lower end including the drum and drive and exciters. The transparent Engine Control Module (ECM) with diagnostic LEDs monitors machine functions for easy operation and troubleshooting.
