The midrange RT80 ride-on trencher from Ditch Witch is powered by a 74.5 hp turbocharged Deutz Tier 4 diesel engine. A compact design and axle capacity give the trencher a static load rating of 39,000 pounds. Features include a tight turn radius, three-speed shift-on-the-fly ground drive controls for improved versatility, along with a standard cruise control system that senses changing load conditions and automatically adjusts. An LCD color display shows engine information and diagnostics. 800/654-6481; www.ditchwitch.com.
