Tree Trimmer

摘要

A tree trimming cluster of circular saws form part of an assembly on the hydraulic arm of a tractor and the assembly is adjustable hydraulically to allow the assembly to sweep from side to side, to incline in relation to the ground and to rotate with a wrist like action. In addition the whole assembly can rotate about a horizontal axis on the hydraulic arm giving an extra degree of adjustment. The hydraulic arm extends from a jib located behind the tractor driver and is capable of slewing. A variety of 4 m cuts are available which is useful for firebreak creation and powerline protection.
