The GeoRipper GR20 Maktia 7301 digs up to 500 mm deep and is engineered for industrial performance but with less weight at only 36 lbs. This mini trencher is powered by Makita's EK7301 that has 73cc's with a full 4.5 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. This compact trencher is a best seller and ideal digging solution for irrigation, root barrier, landscape lighting, and other pipe and wire installations.
