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 4m cuts are available which is useful for firebreak creation and powerline protection. 2013-03-28,C/UsersSharlene/Docu mentsSPECIFICATIONStreewors.completesp,9 C) /I ii co (0 (Y) It -- - (D ' O. / /I, >< it (DA NOJ1 |
