The EZ Kart Throttle Assembly comes with everything you need to install your throttle on an EZ Kart system. Our most popular accessory! EZ Kart allows your handheld trencher to become a full-fledged walk-behind! Great for open areas greater than 25LF in distance. If you are consistently doing longer runs with your GeoRipper this is a must-have accessory. EZ Kart is a two-wheel dolly allowing for easy attachment to GeoRipper. The easy slide-bolt and trigger attachment make digging long distances easy. The two-point attachment system allows for easy on and off giving you all the portability and maneuverability of the GeoRipper as a handheld and the productivity and ease of use of a walk-behind trencher - but with a smaller, lighter foot print.
