1. A machine, comprising:
- an operator seat;
an armrest adjacent the operator seat; and
a control system, includinga control handle extending at least partially upward from the armrest, anda force-feedback device drivingly connected to the control handle and operable to supply feedback force to the control handle, the force-feedback device including at least one of an actuator or a brake, wherein the control system automatically adjusts the magnitude of feedback force supplied to the control handle by the force-feedback device in at least some circumstances.

Abstract
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.

10. A method of operating a machine, the machine having an operator seat, an armrest adjacent the operator seat, and a control system, the method comprising:
-
supporting a control handle of the control system with the control handle extending at least partially upward from the armrest; generating an electrical signal related to one or more aspects of the motion of the control handle and supplying the electrical signal to one or more components of the control system; and supplying feedback force to the control handle with a force-feedback device, including adjusting the magnitude of the feedback force based on one or more operating conditions of the machine. - View Dependent Claims (11, 12, 13, 14)
