Rakes comb their tines or teeth along surfaces to collect loose matter into piles, pull up debris, or distribute materials evenly across an area. Landscape and bow rakes have a wide head with short, rigid tines that spread landscaping materials and remove debris from turf and soil. Leaf and shrub rakes gather leaves, mulch, grass clippings, and other lawn debris. Lake rakes skim off algae, remove aquatic weeds, and clear other debris from ponds, lakes, and pools.
