The Arrow Hammer model 1350T from Arrow-Master is a pneumatic-tired mobile hydraulic hammer that operates both on and off paved surfaces. An 80-hp John Deere diesel engine provides power for the unit and the standard transmission allows the machine to be driven at speeds up to 20 mph. The 1350T breaks, cuts and scores concrete, rock and asphalt into sizes suitable for excavation and recovery. It also compacts and tamps backfill, with adjustable impact up to 13,000 foot pounds.
