With its direct-coupled, high-torque digging chain motor and Tier 4 engine, the RT45 has plenty of power to muscle through the earth—with your choice of trencher, backhoe, earth saw, vibratory plow, microtrencher, or combination trencher/plow attachments—while you enjoy its roomy and comfortable operator’s station. With all of its customer-driven design features, it’s no surprise that the RT45 has been the rental industry’s number one choice in its horsepower class for the last 50 years.
