ABSTRACT:
An electric fence post installer comprising a wheeled frame having a first upstanding support extending upwardly therefrom. A generally horizontally disposed boom arm is rotatably mounted on the upper end of the first support and has a carousel support secured to the outer end thereof. A carousel is rotatably mounted, about a vertical axis, on the carousel support and is adapted to have a plurality of vertically disposed and radially spaced-apart electric fence posts supported thereon. A vertically disposed drill is mounted on the carousel support and is adapted to be rotated and moved downwardly with respect to the carousel support to drill a post hole in the ground. After the post hole has been drilled, a fence post is moved from the carousel to a position over the post hole and then is forced downwardly into the post hole. The installer includes means for ensuring that the post hole will be drilled substantially vertically into the ground.
