Claim:
1. A device for picking up puncturevine burrs disposed on an area of ground, comprising: a cylindrical roller member, wherein the cylindrical roller member has a rotational axis, wherein at least a cylindrical outside surface layer of the roller member is a substantially hard and dense rubber layer, and wherein the rubber layer is adequately soft and resilient such that puncturevine burrs will stick into the rubber layer and be lifted off the ground if the roller member is rolled over the burrs when the burrs are disposed on the area of the ground; a scraper disposed with respect to the roller so that the scraper scrapes the surface of the roller member when the roller member rotates about its rotational axis, and wherein the rubber layer is adequately hard such that the puncturevine burrs do not stick so far into the roller member that the burrs cannot be removed from the roller member by the scraper; a catch disposed with respect to the scraper so that puncturevine burrs that are dislodged from the roller member by the scraper fall into and are retained by the catch as the roller member is rolled over the area of the ground; a support member that holds the scraper and catch with respect to the roller member so that when the roller member rotates about its rotational axis the scraper scrapes over the surface of the roller member; and a handle member that is coupled to the support member, wherein the scraper is attached on the opposite side of the roller member from the handle member.
