Implement carrier and implements

A power machine having a frame and a lift arm operably coupled to the frame at one end of the lift arm, comprising:

• an implement attachment apparatus attached to the lift arm for accepting a primary implement on the lift arm proximal to a second end of the lift arm;
• an implement carrier pivotally attached to the lift arm for accepting a second implement, the implement carrier including a mounting structure configured to receive the second implement in a first position and a second position, wherein the received second implement is oriented with a different attitude in the second position with respect to the mounting structure than in the first position;
• a first actuator operably coupled to the lift arm for selectively providing power to pivot the implement attachment apparatus relative to the lift arm;
• and
• a second actuator pivotally coupled to the implement carrier and the lift arm for selectively providing power to pivot the implement carrier with respect to the lift arm, wherein the second actuator is independently operable with respect to the first actuator;
• and
• an actuator control system including a control valve that is configured to control the second actuator in a first control mode and a second control mode, wherein in the first control mode the control valve is actuable to selectively provide pressurized fluid to control the second actuator to selectively move the implement carrier under power in one of a first and a second direction and selectively prevent movement of the second actuator and in the second control mode, the control valve is actuable to allow the second actuator to move freely and the implement carrier to float;
• wherein the control valve is moveable between first, second, third and fourth operating positions.

A power machine, comprising:

• a frame;
• a lift arm pivotally coupled to the frame;
• an implement attachment apparatus attached proximal to an end of the lift arm for accepting a first implement on the lift arm;
• and
• an implement carrier pivotally mounted on the lift arm for accepting a second implement on the lift arm, including:
• a mounting structure configured to receive and secure an implement thereto in a first attitude and in a second attitude different from the first attitude, the mounting structure having first and second mounting plates each of which is configured to be coupled to an implement;
• a first plurality of mounting features located along the first mounting plate;
• a second plurality of mounting features located along the second mounting plate, each of the second plurality of mounted features being aligned with one of the first plurality of mounting features;
• and
• wherein the first mounting plate has a contoured portion formed along an outer edge, separate from any of the first plurality of mounting features, configured to engage a positioning feature on the implement and having a positioning stop formed into the outer edge such that movement of the positioning feature into the positioning stop aids alignment of the implement in the first attitude.

An implement carrier, comprising:

• a mounting structure configured to be pivotally mounted to a lift arm and further configured to receive and secure an implement thereto, the mounting structure having first and second mounting plates spaced apart by a cross member and an alignment surface extending along one of the first and second mounting plates orthogonal to a main surface thereof engageable by a positioning feature on the implement with the alignment surface having an arcuate portion;
• a first plurality of mounting features located along the first mounting structure surface;
• and
• a second plurality of mounting features located along the second mounting structure surface, each of the second plurality of mounted features being aligned with one of the first plurality of mounting features;
• wherein the mounting structure is configured to receive the implement in a first attitude and in a second attitude different from the first attitude and wherein movement of the positioning feature along the alignment surface aids in aligning a mounting feature on the implement with one of the mounting features on the first mounting structure surface and wherein movement of the positioning feature includes a non-linear path of travel as it moves over the arcuate portion of the alignment surface.
