The Charles Machine Works (CMW), Inc., manufacturer of Ditch Witch underground construction equipment, has introduced a new line of compact and powerful walk-behind trenchers — the RT12, RT16, RT20 and RT24. The entire line incorporates a stacked, in-line hydraulic pump configuration that effectively eliminates vertical shafts and the use of belts and/or flywheel reduction systems, and ultimately reduces downtime. They also have fully hydrostatic ground drives, with simple-to-use, hydraulic, skid-steer-style steering. Ditch Witch walk-behinds feature a solid, adjustable trail wheel that helps keep the unit stable and reduces breakover when loading, unloading and traveling over curbs and other uneven terrain. Also, to keep the trencher boom in the ground during operation and/or maintain down pressure when placing the boom in the ground, the trail wheel gives the machine another point of leverage besides the track undercarriage.
