ABSTRACT:
A hydraulic stone picker adapted for use in conjunction with a modified front-end loader. The fork is pivotally mounted to the side of the front-end loader which has been modified by addition thereto of a front and extended side walls to define a collecting bin. Stones dislodged by the fork are transferred to the collecting bin by actuation of a hydraulic ram which rotates the fork from a lowered to a raised position. The apparatus is provided with support members to prevent damage to the fork during use. The linkage of the fork to the hydraulic ram includes a lost-motion connection which permits the fork to pivot during use to accommodate surface irregularities.
