A power split and creep drive system for street sweeper or like specialty vehicle having a single engine is disclosed. The system intends to retrofit and convert on-highway truck chassis into specialty vehicles capable of performing work function and moving at creeping speed, such as a street sweeper. It includes a hydraulic work circuit or power-take-off (PTO) port, a planetary gear set, a hydraulic system comprising pumps and motors to drive the working devices and balance the demand between propulsion and work function such as sweeping. The planetary gear set includes an input shaft connecting to a transmission output shaft of the chassis, a first output shaft connecting to a hydraulic machine, and a second output shaft to vehicle propulsion drive shaft.
