A drive system for a mobile machine is disclosed. The drive system may have an engine, a mechanical step-change transmission operatively connected to and driven by the engine, and a controller in communication with the engine and the mechanical step-change transmission. The controller may be configured to receive a first operator input to store as a target a current groundspeed of the mobile machine and a current gear selection of the mechanical step-change transmission, and receive a second operator input to recall the target when at least one of the groundspeed of the mobile machine and the gear selection of the mechanical step-change transmission is different from the target. The controller may further be configured to adjust a speed of the engine and a gear selection of the mechanical step-change transmission to achieve the recalled target.
