Abstract
A tree shaker pad for each of the clamping jaws of a nut or fruit tree shaker. The tree shaker pad includes a hollow pillow of cylindrical or oval shaped cross-sectional configuration of resilient material with the pillow being substantially filled with a plurality of resilient members having void area or interstices therebetween. The pillow is provided with a water or other liquid coolant inlet at one end and a water or liquid coolant outlet adjacent the other end of circulation of water or liquid coolant through the pillow when the jaws of the tree shaker are in unclamped relation to the tree trunk. The resilient members, preferably rubber balls, are compressed when the jaws are in clamping relation to a tree trunk and will maintain a degree of flexibility and elasticity to provide better conformity of the pad with the tree trunk when the jaws are in clamped position. The rubber ball forming the filler medium will return to their original configuration when the jaws are moved to unclamped position thereby returning the void areas or interstices to their original size and communication for circulation of water or liquid coolant through the pillow for maintaining optimum operating temperature of the tree shaker pads on the clamp jaws of the tree shaker.
