A lawn rake (100) has a cross head assembly (130) attached to a handle (120). A truncated tee (150) mounted on the cross arm (145) of the cross head assembly (130) receives the handle (120). A plurality of tines (170) is carried by the cross arm (145). The cross arm (145) is tubular and has a plurality of pairs (162) of apertures (164). The apertures (164) are larger than the cross section of the tines (170). The tines (170) are inserted through, and loosely positioned by, the apertures (164). The plurality of tines (170) forms an array (160) that is generally coplanar. The array (160) may form an obtuse angle with respect to the handle (120). Embodiments of the rake include arrays of tines (170) configured to form alternating rows of tines or a curvilinear arrangement of tines. A looped bend (178) formed in the end of each tine (170) distal to the ground engaging tip (176), snaps around the cross arm (145) to pivotally mount each tine (170). The tines (170) are replaceable, and are mountable on and removable from the cross arm (145) by application of finger force. The tines (170) are releasable. During raking action, an impact load directed upwardly on a tip (176) may cause release of the looped bend (178) from the cross arm (145), thereby preventing breakage of the tine (170). The lawn rake (100) can be used in a push mode. The lawn rake (100) may be distributed as a kit of parts. Components of lawn rake (100) are preferably made from a thermoplastic material. In particular the thermoplastic material may be polyvinylchloride.
