ABSTRACT:
The present invention is directed to a tree follower device. The tree follower device includes an engagement assembly that penetrates into and shakes the branches of fruit trees to dislodge the fruit. A pressure transducer in communication with a controller measures the pressure resistance from engagement with the branches and moves the tree follower device further into and out of the branches depending upon the resistance. The present invention allows for programming various upper and lower limits and for operating in different modes for different types of trees. The present invention also provides for varying the sensitivity and the speed at which the engagement devices moves into or out of the tree.
