ABSTRACT:
A tree-trimming and phoning machine has a cutter bar (2) with a plurality of in-line-staggered rotary cutter blades (1) that are rotated by a separate hydraulic motor (12) for each one of the plurality of the rotary cutter blades. A resulting plurality of blade-turning hydraulic motors (12) are connected in series to a hydraulic-motor line 15. Hydraulic relief lines (23) are in pressure-spike-relief communication between hydraulic-motor lines (1 5) intermediate the hydraulic motors (12) and a hydraulic manifold or header (24). The cutter bar is attachable to a single side or to both sides of a hydraulic lifting means (5) such as employed for standard front-end loaders, fork lifts and other lifting means that are attachable to a vehicle (6) such as a tractor. The hydraulic lifting means is maneuverable university to select positions of trimming, pruning and cutting-load dumping. A selection of sizes of saw-blade cutter bars are attachable to a variety of hydraulic lifting and maneuvering machines that are attachable to a variety of sizes and types of agricultural and industrial tractors.
