As far as 'cutting' and leveling with landscape rake.. i guess big ones might weigh enough and have strong enough tines to break into the ground more, but my little one won't.
BUT, it is actually very good at spreading/leveling loose stuff. I like it more for that use than the regular back blade.
Part of the reason i bought an ATV rake that uses 2" square tube to mount vs a small 3pt item is that I wanted the option to extend the thing to silly lengths, including possibly for FEL use (although i havent done it yet). For example, on a really long mount/pole you can raise the thing many feet in the air and grab down on top of a bush you've pulled up or knocked over and drag that.
Also, important to remember that top link setting affects what it does just like a box blade or back blade. If you want it to scrape more aggressively or hold and drag a pile better you extend the top link. If you want to work very lightly you can retract the top link. It's maybe not as big a difference as on a blade but it's a noticeable effect.
