A garden rake is a tool with tines or teeth used to gather leaves, grass, and other debris, as well as to level and loosen soil. On the other hand, a garden leveler is a tool used to even out soil or gravel by dragging it across the surface to create a flat, smooth finish. So, while both tools are used for gardening tasks, a rake is more versatile for various purposes, while a leveler is specifically designed to create a smooth surface.
