  • Patent number: 10156055
    Abstract: A tool coupler assembly may include a power linkage assembly, and the power linkage assembly may include a first power link. The first power link may include a first end configured for pivotal connection to a tool, and a second, opposite end configured for pivotal connection to one end of a tool control actuator. The tool control actuator may be connected at an opposite end to a first end of a tool support member of a machine, wherein operation of the tool control actuator pivots the tool about a tool pivot axis coaxial with a tool engagement interface at a second end of the tool support member. A power linkage actuator may be pivotally connected at a first end for coaxial rotation with the tool engagement interface at the second end of the tool support member, and at a second end for coaxial rotation with the first end of the first power link.
