ABSTRACT:
A method of lifting a boom assembly for a machine along a lift path is provided. The machine has a work implement coupled to the boom assembly. The method includes initially moving the work implement vertically from a lowered position to a first intermediate position forward of the lowered position. The method also includes subsequently moving the work implement vertically from the first intermediate position along a slightly rearwardly inclined direction to a second intermediate position rearward of the first intermediate position. The method also includes subsequently moving the work implement vertically from the second intermediate position along a slightly forwardly inclined direction to a third intermediate position forward of the second intermediate position. The method also includes finally moving the work implement vertically from the third intermediate position along a slightly rearward inclined direction to a final position rearward of the first, second, and third intermediate positions.
