Abstract
A hydraulic control system for use with a work machine. The work machine has a platform which supports an operator. When the operator is not on the platform, the platform moves into a first position, causing a signal generator to send a signal to a controller. The controller is configured to limit the hydraulic flow to the ground drive motor when the platform is in the first position. The controller may directly reduce operation of the engine, or may adjust a valve which diverts a portion of hydraulic flow. The limitation may be overridden when desired by the operator.
