The attachment includes a cradle for supporting a motorized auger in pendulum-like fashion so that true vertical disposition of the auger may be obtained. When the motor is energized and the supporting portion of the loader is lowered relative to the ground with which the auger is engaged, a substantially true vertical hole is bored in the ground. Further, the hydraulic motor is reversible whereby after a hole has been bored removal of the auger is facilitated.，下面是Tractor mounted hydraulic posthole digger专利的具体信息内容。

权利要求

1. An earth boring attachment for a loader vehicle having a lift member, said attachment comprising a first outer frame including mounting means for removable support from said lift member, said frame being generally horizontal and including opposite side marginal portions, a second generally horizontal inner frame disposed within said outer frame and including opposite side portions pivotally supported between said opposite side marginal portions for angular displacement about first aligned axes extending between said side portions and side marginal portions, said second frame including a second pair of opposite side portions disposed in an upstanding plane normal to an upstanding plane containing said axes, and a mounting frame including depending opposite side members whose lower end portions are pivotally supported from said second pair of opposite side portions of said second frame for angular displacement about second aligned axes extending therebetween, and a torque producer removably supported from an upper portion of said mounting frame above said first and second aligned axes and including a depending rotary output shaft drivingly coupled to the upper end of an upstanding auger shaft.

2. The combination of claim 1 wherein said mounting means including a pair of parallel tube members fixedly supported from said first frame and adapted to be telescoped over parallel tines carried by said lift member.

3. The combination of claim 1 wherein said mounting means including a pair of parallel tube members to which opposite sides of said first frame are removably attached and adapted to be telescoped over parallel tines carried by said lift member.

4. The combination of claim 1 wherein said mounting means including a pair of clamp assemblies to which opposite sides of said first frame are removably attached, said clamp assemblies including clamp portions adapted to be removably clampingly engaged with an earth bucket carried by said lift member head.
