1. A power machine system comprising:
a first power machine, including:
a first main frame;
a first workgroup work element movably supported by the first main frame;
a first power source;
a first actuator arranged to receive power from the first power source to move the first workgroup work element relative to the first main frame;
a first user input device supported by the first main frame and configured to transmit control signals based on inputs provided by a user at the first user input device; and
a first control device;
the first control device including first one or more processor devices configured to:
receive, from the first user input device, a control signal corresponding to a power-machine operation; and
cooperatively control execution of the first power machine and a second power machine to complete a work task, selectively under either of:
a local control mode, in which the first control device controls the first power machine via the first actuator, based on the control signal, to move the first workgroup work element relative to the first main frame; or
a remote control mode, in which the first power machine controls the second power machine via the first control device transmitting a wireless signal to a second power machine, based on the control signal, to control operation of a second actuator of the second power machine to move a second workgroup work element relative to a second main frame.
