The present invention relates to a hollow boring auger for use for poles, including a first and second mounting part moveably connected, one to the other, to substantially encircle the pole. A first and second auger part are also included, correspondingly attachable to the first and second mounting part, to substantially encircle the pole, A rotation apparatus associated with the mounting parts and the auger parts is included such that in use the auger parts can be rotated about the pole to bore a hollow trench about the pole. The invention also relates to a method of use.

A method of cutting a microtrech in which the buried utility is exposed by opening an access hole in a roadway above the buried utility using a roadway access hole drill that rotates and vibrates the drill bit. A roadway access hole drill having a down-the-hole jack-hammer drill bit and a motor to rotate the down-the-hole jack-hammer drill.

A system and method for automatically adjusting a pressure within a variable volume of a hydraulic feed tube while the variable volume of the hydraulic feed tube is changing. Inputs are used to determine the appropriate pressure adjustments for the hydraulic feed tube, which is adjusted by a pressure reducing valve, wherein control of the pressure reducing valve is updated continuously by a control module.

An auger attachment system for an extendable boom having a first stage, and a second stage, the auger attachment system having a fixed mounting configured to couple to an auger, the fixed mounting being coupled to the second stage of the extendable boom, an extendable mounting, configured to couple to the auger, the extendable mounting being coupled to the first stage of the extendable boom, and a linear actuator configured to extend and retract the extendable mounting to transfer the auger from the extendable mounting to the fixed mounting.

Disclosed embodiments include post driving implements which attach to a power machine such as a loader in order to pick up posts of various sizes and materials and/or to drive the posts into the ground. In some exemplary disclosed embodiments, the post driving implement allows a post to be picked up when positioned inline with a direction of power machine travel and allows the post to rotate under the force of gravity to a second position in which the post is inline with a pounding mechanism for pounding the post into the ground. Catch mechanisms can be included to capture a portion of the implement to maintain the post in the second position until a release action is taken or a release command is given.
