Tree harvester provided with a rotatable worktable

摘要

A tree harvester provided with a rotatable worktable assembly is disclosed herein. The tree harvester includes a movable frame, a worktable assembly rotatably mounted to the movable frame and an upper frame rotatably mounted to the worktable assembly. The upper frame is provided with an articulated boom that includes a feller/grapple head. The worktable assembly includes a tree delimbing mechanism, a tree cutting mechanism and a log stacker. The operation of the worktable is advantageously automated so that the operator can use the boom while the worktable is processing a tree. The position of the worktable between the movable frame and the upper frame makes the tree harvester more compact than conventional tree harvester, while the independent rotation of the worktable assembly and of the upper frame with respect to the movable frame increases the flexibility of operation of the tree harvester.
