Abstract: Apparatus are described that may serve as guards that protect partially buried sprinkler heads from impact damage. These apparatus each include an inner frame, an outer frame, and several wall members. The outer frame encircles the inner frame, and the wall members occupy the space between the two frames. The inner frame, the outer frame, and the wall members combine to partition the space into a plurality of compartments. At the same time, a top of the inner frame is higher than a top of the outer frame, and the wall members define a ramp between the top of the outer frame and the top of the inner frame. The apparatus may serve to cause a wheel of a lawnmower that would normally impact the sprinkler head to harmlessly pass over the sprinkler head without damage.
