Maybe light thatching but not aerating. I could use it to get light overgrowth but not a full detatcher that would need stronger tines
No it does not
I did not find it at any store zip 55960 Home Depot should handle them.
Very well. I have a 70' pine tree and this rake really does the job.
I'm not sure what you mean by teardrop shape. The handle is round and still metal. I hope this answers your questions.
Unit is quite durable. Excess wear and tear but not likely. I have had these rakes for over 3 years and I can say, its the best that have I used in the thirty years I've been raking
No The price is so good just buy another one.
I believe resin, which is a plastic? The tines can lift and bounce over large rocks, roots, etc, almost metal like.
