GeoRipper 620 is our most popular minitrencher. It provides a fast trenching solution and lighter digging alternative. Powered by a 61cc engine with a full 4.4 HP for everyday narrow trenching applications. It’s engineered to start easier and vibrate less. It also has innovative features like Stratified Air Scavenging (SAS) that recovers up to 75% of unburned fuel to reduce fuel consumption, and a cyclonic air intake that discards larger debris for increased air filter life – and less maintenance. The compact and efficient GeoRipper 620 is an ideal digging solution for irrigation, root barrier, landscape lighting, and other pipe and wire installations that require 20″ or less in digging depth.
