Abstract: An auger attachment assembly for tractors and related vehicles. The assembly comprises a telescopic arm with a descending auger device affixed to a distal end thereof, functioning to allow a user to utilize the auger from a convenient sitting position. The invention utilizes hydraulic power, which is achieved by using existing tractor hydraulics, or by installation of a power take-off pump and reservoir on the frame of the implement. In the preferred mode, the arm attaches to the lawn tractor via traditional three-point hitch, though additional attachment means may be utilized. When engaged, the arm telescopes to a desired distance, and can move from left to right at approximately 180 degrees, providing the operator with significant versatility. The auger raises and lowers on a fixed track, which functions to keep the same from “wandering,” as is common in the prior art.

Abstract: The movement of relocatable racing rails (10) by manual labor involves the extraction of poles (16) from the ground and re-insertion of each pole a fixed distance from its adjacent pole along the path of the new location of the racing rail, thereby resulting in a time consuming and very labor intensive operation wherein inaccuracies in placement of the poles can result in misfits of the relocatable rails over the poles, whereby readjustment is often required. A transportation apparatus (28) is provided for carrying poles (16) and measuring a fixed distance between the last pole and a pole driver mechanism (32) for driving the next pole (66) into the ground. The pole driver is allowed to move relative to the transportation apparatus as the apparatus moves along the ground, but the relative movement is arranged so as to maintain a fixed distance to the last pole for a time shortly before, during and after the pole driver mechanism is actuated to drive a pole into the ground.
