ABSTRACT:
In a down-the-row type of tree shaking apparatus, a support frame is pivotally mounted to a carrier vehicle for rotation about an axis which is parallel to the longitudinal axis of the vehicle, and a suspension frame, from which a tree shaking and clamping assembly depends, is pivotally mounted to the support frame for rotation about an axis which is transverse to the longitudinal axis of the vehicle. The shaking and clamping assembly includes a housing and a pair of clamping arms which are pivotally mounted to the housing for rotation about parallel axes which are perpendicular to the transverse axis of rotation of the suspension frame. Each clamping arm is retractable from the position it assumes during shaking through an arc of approximately 90.degree., and each arm is operated by a separately controllable hydraulic cylinder. After shaking a tree in a particular row, both arms are retracted to positions which are generally parallel to the longitudinal axis of the vehicle to enable the vehicle to move directly forward; and before arriving at the next tree in the row, the rear arm only is extended outwardly to its tree-engaging position. The extended rear arm is then used by the vehicle operator as a visual reference for maneuvering the vehicle to a position whereat the extended arm abuts or is closely adjacent to the next tree in the row to be shaken. When the rear arm is in such position, the front arm is extended to tightly engage the tree and bring both of the clamping arms into tight clamping engagement with the tree. The tree is then shaken.
