Drive system having operator-selectable control modes

A drive system for a mobile machine, comprising:

• a power source configured to generate mechanical power;
• a transmission driven by the power source
• a traction device driven by the transmission;
• a first input device configured to generate a signal to operate the machine;
• a second input device configured to receive an operator selection of one of a plurality of transmission modes;
• and
• a controller in communication with the first input device and the transmission, the controller being configured to adjust operation of the transmission to control a speed rate of change of the traction device in response to the signal from the first input device and based on the operator-selected one of the plurality of transmission modes,
• wherein the machine includes a tool system operatively driven by the power source;
• the first input device includes a tool system input device movable through a range from a neutral position to a maximum displaced position;
• and
• the controller is further configured to adjust an output torque of the transmission according to an operator-selected one of the plurality of transmission modes and based on a position of the tool system input device.
