Abstract:
1. A work machine, comprising: a power device comprising a rotary output, a range selector input configured to select a range, a traction element, a transmission configured to provide a transmission ratio between the power device and the traction element, where the selected range corresponds to a plurality of transmission ratios, an operator input device selectively configured to have a plurality of positions, and a control system operatively coupled to the power device, the control system comprising a first performance curve and a second performance curve, each of the first and second performance curves expressing torque of the power device as a function of rotational speed of the rotary output of the power device; wherein, the first performance curve includes a first no-load speed and the second performance curve includes a second no-load speed which is equal to or greater than the first no-load speed; further wherein, for a given transmission ratio, a given operator input device position, and given range selector input, the control system is configured to switch the power device between the first performance curve and the second performance curve.
