Automatic Hydraulic Speed Control Abstract of the Disclosure A microprocessor based control for a hydraulic pump motor used to control the operation of a mast assembly on a work vehicle. The speed of each function performed by the mast assembly is programmable to one of a plurality of possible speeds. An additional function for performing lifting of the mast produces incremental speed variations relative to incremental movement of a corresponding control lever. Each of the functions have a predetermined priority such that attempted operation of multiple functions results in a pump motor speed requested by the function of highest priority.
