A machine includes an operator seat and an armrest adjacent the operator
seat. The machine may also include a control system, which may include a
control handle extending at least partially upward from the armrest. The
control system may also include a force feedback device drivingly
connected to the control handle and operable to supply feedback force to
the control handle. The force-feedback device may include at least one of
an actuator or a brake. Additionally, the control system may
automatically adjust the magnitude of the feedback force supplied to the
control handle by the force feedback device in at least some
circumstances.
