The RT600 riding trencher from The Toro Company is built to deliver smooth, consistent performance in tough digging conditions. Its PowerTrench trencher drive incorporates a flywheel, torsion shaft and planetary gearset design. The planetary gearset multiplies the hydrostatic motor torque, while the flywheel and torsion shaft design store inertial energy, which is then released in tough conditions to deliver powerful and consistent trenching performance. It has a 65 hp Cummins B3.3 four-cylinder, liquid-cooled diesel engine. The dual hydrostatic system provides optimal performance for trenching and plowing. It has four-wheel steering for maneuverability and incorporates crab steering for improved handling on slopes. 855/493-0088; www.toro.com
