With the five models in the Dash-7 excavator line, Komatsu continues to expand the utility of on-board electronics with its new Equipment Management Monitoring System. The display in the cab allows the operator to monitor real-time performance data and fault history. While running an attachment, the operator can also easily adjust directional hydraulic flow and oil volume. Komatsu claims improved productivity per gallon of fuel burned, too. List prices: $185,000 to $345,000.
