American Augers’ EarthPro Raptor Series is a low-profile, 1.65” anti-backflex digging chain that is highly resistant to wear and tear.   The design eliminates components such as spacers and spreader bars, which means fewer parts to stock and service. The chain can be installed in minutes with simple hand tools.   The Raptor comes with a 1-year/1,000-hour warranty on the bare chain.  It fits all makes of trenchers and is only available at your local Astec Underground dealer.
