A device usable for picking up puncturevine burrs comprises a cylindrical roller member, a scraper, a catch, a support member, and a handle member. The cylindrical roller member has a rotational axis and has an outside surface layer made of a resilient material such that the burrs will readily stick into the material. The scraper scrapes the surface of the roller member when the roller member rotates about its rotational axis. The support member holds the scraper and catch so that the scraper scrapes over the surface of the roller member during rotation. In operation, a user pushes the device over the area of the ground with burrs. Under the weight of the device itself, the burrs are picked up by the roller member and are scraped off of the roller member by the scraper, and are retained by the catch. Burrs that collect in the catch are disposed of.
