Abstract

A forestry machine includes a ground propulsion apparatus, a chassis supported by the ground propulsion apparatus, a cab, an engine and a work implement. The chassis includes a front chassis portion and a rear chassis portion. The front chassis portion includes an upper portion and a lower portion. The rear chassis portion has a wood basket supported thereon. The cab is rotatably supported on the front chassis portion by a rotatable connection about a cab rotation axis to be selectively rotated 360 degrees. The engine is integrated into the front chassis portion. At least a part of the engine is disposed below an upper most surface of the upper portion. The work implement is movably attached to the cab. The work implement includes a boom movably attached to the cab, an arm movably attached to the boom, and a work tool attached to the arm.

Abstract

A machine (A) includes a frame (16) and a platform (58) on which a boom assembly (B) is mounted. Two arms (332) of a U-shaped pivotal member (330) are pivotably mounted to the frame (16) about a first pivot axis (380) perpendicular to a longitudinal direction of the frame (16). A front end (302) of a mounting plate (310) is pivotably connected to an intermediate section (336) of the pivotal member (330) about a second pivot axis (382) perpendicular to and spaced from the first pivot axis (380). Two rams (400) are mounted on opposite sides of a rear end (304) of the mounting plate (310). Each ram (400) includes a lower end (404) pivotably connected to the frame (16) and an upper end (402) pivotably connected to one of the sides of the mounting plate (310). The boom assembly (B), the mounting plate (310), and the pivotal member (330) pivot about the first pivot axis (380) and/or the second pivot axis (382) relative to the frame (16) due to relative movement of the rams (400).
