A tree harvester including an automated tree sensing and shaking control system. The control system includes a tree sensing device, such as an ultrasonic sensor that is mounted upon the harvester. Predetermined tree distance values and other shaker head control parameters are input into a programmable logic control (PLC) device of the control system. When the harvester is located next to a tree, the operator initiates an automated tree shaking cycle in which the tree sensor provides distance values to the tree as input signals to the controller. The shaker head automatically moves outward towards the tree until the inputted distance values to the tree are equal to or less than the predetermined tree distance values. The control system then causes the shaker head to clamp the tree, to shake the tree, to unclamp the tree and to move the shaker head back to the harvester.
