I like the Harley Rake, and the size of tractor depends on the size of rake you get for the 3pt. Otherwise, get a tractor that has good visibility of the rake in back, and good manuverability with HST and 4wd. Should be able to get the larger 3pt Harley rake and power it with a 30-35 HP tractor without any problem. I would get the FEL too, as it can be used to scoop up the windrow of rocks and debris lined up after using the rake. Its a good way to go, but the best for you would be to run one first, or see one operate. Short of that, find a landscaper that runs one. They seem to swear by them, and its become a very popular attachment. A show of landscapers and municipal people recently seemed to have a Harley Rake on every brand of tractor and skidsteer, from NH, JD, Bota, Cat, Bobcat, etc, etc. That by itself indicated they are the attachment to be buying. I rent one whenever I need it, and find it to be very versitile.
