ABSTRACT:
Apparatus serving the combined functions of maintaining a grove or orchard in properly trimmed as well as topped condition, comprising a vehicle adapted for movement along the ground in a direction essentially parallel to and adjacent a row of trees. A generally U-shaped structural member is operably mounted upon the vehicle, with this member having a pair of arms, one disposed on each side of the vehicle, and with the base portion interconnecting these arms being disposed at a forward location on the vehicle. The end of each arm remote from the base portion is rotatably mounted to an attachment point located on the frame of the vehicle, and devices such as actuators are utilized for bringing about selected movements of these arms about their attachment points, thus to change the effective height of the base portion with respect to the ground. The base portion serves as the mounting for a pair of booms, upon each of which, a multiplicity of saw blades are mounted. These saw blades are comparatively closely spaced, and upon being driven in rotation, can carry on an effective hedging operation when the saw booms are generally vertically disposed, and a topping operation when the booms are essentially horizontally disposed in an elevated position. Advantageously, the base portion can, in accordance with this invention, be rotated with respect to the arms between a position appropriate for the saw booms to bring about a hedging operation, and a position appropriate for the saw booms to conduct a topping operation.
