Abstract
The present invention relates to a travel speed control for a hydrostatically propelled harvesting machine or the like, and more particularly to a control system which automatically slows the travel speed of the harvesting machine at a fast rate in response to lugging of the engine and subsequently allows recovery of the travel speed to be at a fast rate initially, followed by a slow recovery rate to insure stability of the control system while minimizing the time required for travel speed recovery.
