Astec Underground
The Astec RT1200 can trench as deep as 84-inches and from 7 to 18 inches wide. Choose the attachments you need from a tough tool kit that includes optional attachments like a trencher, vibratory plow, backfill blade, backhoe and rock saw. A tilt frame and rubber tracks are also optional. Ergonomic controls are at your fingertips from the easy-access operator’s station. The 121-hp 4-cylinder turbo-charged B4.5 diesel Tier 3 Stage IIIA Cummins engine is both fuel efficient and powerful. Four-wheel steering makes the RT1200 highly maneuverable. Crab steering is useful on slopes when countering tractive effort. Outboard planetaries and differential locks are standard features. Hydrostatic ground drive and hydrostatic attachment drive provide optimum footage for trenching or plowing. The Astec trencher design features a flywheel, torsion shaft and planetary gearbox for smooth operation and long life. A flywheel minimizes trencher stalls in tough digging conditions and reduces pressure spikes. The torsion shaft absorbs shock loads from the driveline. And planetary gears multiply the hydrostatic motor torque to provide excellent digging power. 865.458.8575, astecunderground.com
