Abstract
The multi-drill mounter allows any combination of two jack hammers, drills or augers to be simultaneously mounted on a tractor and the like. A flat back panel supports an upper and lower horizontal track. Upper and lower sliding brackets support a pair of vertical derricks. Each derrick can hold a drilling tool such as a jack hammer. In operation the active drilling tool is hydraulically pushed to the center of the derrick while the inactive drilling tool is moved to the side. The multi-drill mounter can also be tilted to allow the use of an auger for drilling wide holes.
