Abstract
A sweep removal tool includes a pair of claws with angled surfaces conforming to the top edge of the sweep stem to locate the tool and help distribute sweep removal impact forces. A retainer depressor centered below the claws moves the retainer to a release position and slides between the angled surfaces during sweep removal. The depressor shape assures desired tine contact, even when the sweep is at an extreme position in the range of possible mounted positions, while preventing damaging contact as the depressor moves relative to the retainer during sweep removal. A curved surface extends between the claws and the depressor and facilitates free pivoting of the tine about the claw contact points to depress the retainer. The tool bottoms against the sweep when the depressor is moved to the release position to prevent retained damage from removal impact forces.
