Welcome Tom,
Although I have not used a landscape rake, and am interested in one myself, I think it would work pretty well if your terrain is fairly level. I mentioned that I was interested in a landscape rake, but before I buy one, there is a place locally where I can rent one for a few bucks on a weekend and see how it performs. From that experience, I will determine if I want to invest in one or not.
Only my 2 cents.... I'll bet you will get a response/s from folks that have "been there and done that".
Regards,
Jake
