Abstract
A method of verifying proper coupling of an implement assembly to a lift arm assembly by an operator who is located in a cab of a work machine is disclosed. The work machine includes the implement assembly and the lift arm assembly. The implement assembly includes a hinge plate. The hinge plate has a first coupling aperture extending therethrough. The lift arm assembly has a lift arm and a cylinder. The cylinder is secured to the lift arm. The method includes the step of actuating the cylinder so as to move a pin from a first pin position to a second pin position. The pin is spaced apart from the first coupling aperture when the pin is located in the first pin position. The pin extends through the first coupling aperture when the pin is located in the second pin position. The method further includes the step of viewing the pin when the pin is located in the second pin position by the operator from a position within the cab whereby proper coupling of the implement assembly to the lift arm assembly is verified by the operator without having to exit the cab.
