Abstract: An improved rock picker system includes a prime mover, with an operator's cab and towing means; windrow means detachably and foldingly mounted to the prime mover front; collector means; separator means; transfer means; dump trailer means detachably connectable to the prime mover towing means; an hydraulic power supply in fluid communication with the hydraulic loads; and, control means for controlling the hydraulic power supply and hydraulic loads individually. Control means includes a plurality of remotely operated hydraulic control valves corresponding to the hydraulic loads and a control panel in electrical communication with the remotely operated hydraulic control valves, and speed control means for controlling the speed of the hydraulic loads.
