  • Patent number: 9643648
    Abstract: A work vehicle is disclosed with a propulsion system that is selectively operable in a first, turning mode or a second, straight mode. The vehicle includes a first traction device, a second traction device, a first steering input, and a second steering input. In the first, turning mode, an operator is able to steer the vehicle left, right, or straight by independently operating the first and second traction devices via the first and second steering inputs. In the second, straight mode, the operator is able to steer the vehicle straight by operating both the first and second traction devices together via one of the first and second steering inputs.

  • Patent number: 9644345
    Abstract: The present disclosure provides a method of controlling a drive speed of a drive unit powering a work machine. The method includes determining if a control switch is in an enabled position and detecting if a control mechanism is moved within a defined period of time to operate the machine to perform a function. The method also includes detecting if a control means has been positioned in the active state once the control mechanism is not moved within the defined period of time. The method further includes sending a signal to a drive unit controller to shut off the drive unit when the control means is triggered to the active state. The drive unit is turned off as electrical energy continues to be provided from an energy storage device to at least the vehicle control unit, drive unit controller, and sensor after the drive unit is turned off.

In the first, turning mode, an operator is able to steer the vehicle left, right, or straight by independently operating the first and second traction devices via the first and second steering inputs. In the second, straight mode, the operator is able to steer the vehicle straight by operating both the first and second fraction devices together via one of the first and second steering inputs.
