A mobile collector or harvester for weed seeds that are normally discharged onto the ground during a combining operation, is connected to trail a conventional grain combine, and collects the straw and the tailings discharged from the separating sieve that normally discharges small chaff and seeds onto the ground. The harvester frame has a conveyor for conveying straw and chaff onto a separate shaker screening member, which is of size to let the small weed seeds drop onto a grain pan and then into a hopper, while the straw is retained on the top of the screen and discharged onto the ground. A separate auger conveyor is used for elevating the weed seeds from the hopper into a storage tank, which is then periodically emptied through the use of another auger conveyor. The entire unit is self-contained including an internal combustion engine power unit, that drives a hydraulic pump for operating hydraulic motors through suitable valves. The apparatus as shown has its forward end connected directly to the combine, and caster wheels at the rear so that it will trail properly and will turn easily. Other forms of support also can be used.
