The RT20 from Ditch Witch is a 20-hp walk-behind trencher that features a stacked, in-line hydraulic pump configuration to eliminate vertical shafts and the use of belts and flywheel reduction systems. The fully hydrostatic ground drive has skid-steer-style steering. The trail wheel gives the operator an additional point of leverage besides the track undercarriage, which facilitates keeping the trencher boom in the ground during operation. The units come with a choice of high-flotation tires or heavy-duty DuraTraks. www.ditchwitch.com/
