Powered by a 121-horsepower, Tier-3 Cummins B4.5 turbocharged engine, the new RT1200 can trench up to 84 inches deep and from 7 to 18 inches wide, but still use attachments common to the previously-largest Astec Underground ride-on trencher model, the RT1160. The RT1200, introduced at the ICUEE trade show, is able to use a combination of such attachments as trenchers, vibratory plows, backfill blades, backhoes, cable reels and rock saws. The availability of four-wheel, crab and coordinated steering allows productivity in various worksite conditions. Rubber tracks and a tilt frame are optional.
