  • Patent number: 6116847
    Abstract: A lift assembly for lifting an implement relative to a frame of a work machine is disclosed. The lift assembly includes a lift arm having a frame pin bore, a cylinder pin bore, a linkage pin bore, and an implement pin bore. The frame pin bore and said cylinder pin bore define a first line. The frame pin bore and said implement pin bore define a second line. The second line is located above said first line. The first line and said second line define an angle which is greater than three degrees. A plane intersects said first line at a center point of said cylinder pin bore and is normal to said first line. A said plane divides said lift arm into a frame-side segment and an implement-side segment. The first line includes a first segment which is entirely coincident with said implement-side segment of said lift arm. The linkage pin bore is defined in said frame-side segment. The lift assembly further includes a tilt lever which is pivotably coupled to the lift arm at said linkage pin bore.
