The Arrow-Master Arrow Hammer Model 1350T is a pneumatic-tired, mobile hydraulic hammer that operates both on and off paved surfaces. An 8-hp John Deere diesel engine provides power for the hammer. The 1350T breaks, cuts and scores concrete, rock and asphalt into sizes suitable for excavation recovery. It also compacts and tamps backfill with adjustable impact up to 13,000 foot-pounds. Standard features include mechanical or electronic stroke control, ROPS, a pivoting mast for maximum impact on uneven surfaces, stoplights and reflectors, and a mechanical back-up alarm.
