SELF-LEVELING LIFT ARM ASSEMBLY FOR POWER MACHINES
A lift arm assembly for a power machine can include a lift arm, an implement carrier, a lift cylinder that raises or lowers the lift arm, a leveling link, a tilt cylinder that causes the implement carrier to pivot relative to the lift arm, and an isolated hydraulic circuit. The isolated hydraulic circuit can include a follower cylinder that is mechanically synchronized with the lift cylinder, a leveling cylinder that can be pivotally secured to the leveling link and to the lift arm, a first conduit that can provide hydraulic flow between base ends of the follower and leveling cylinders, and a second conduit that can provide hydraulic flow between rod ends of the follower and leveling cylinders. Movement of the follower and leveling cylinders can be hydraulically synchronized by flow through the first and second conduits.
