Series 2000 includes four chain-type trencher models — TT-2000C, TT-2300C, TT-2500C and TT-2700C — that provide horsepower ratings from 300 to 830 from Cat engines. Operating weights range from 75,000 to 300,000 pounds. Cutting widths range from 12 to 72 inches, with cutting depths to 24 feet. The mechanical-drive design allows the chain to move slower in first gear (compared to hydrostatic-drive) to break up (not grind) the rock. The mechanical drive system provides four, high-torque digging speeds.
