Claim of US Patent No. 10,189,512

1. A control linkage between an operator input assembly in a cab of a power machine and an actuator coupled to a frame of the power machine, the control linkage comprising:a junction mechanism configured to make a connection between the operator input assembly and the actuator when the cab is moved to an operating position relative to the frame of the power machine, and configured to break the connection between the operator input assembly and the actuator when the cab is moved to a service position relative to the frame of the power machine, the junction mechanism including a first junction portion operably coupled to the operator input assembly and a second junction portion operably coupled to the actuator, wherein the junction mechanism includes an engagement portion having a pair of fingers defining a tapered opening coupled to one of the first junction portion and the second junction portion, and an engagement portion having a protrusion coupled to the other of the first junction portion and the second junction portion such that the protrusion is guided into the tapered opening by the pair of fingers when the cab is moved from the service position to the operating position.
