I used mine today, still cleaning up after the nasty October storm.
I can't say how much better the wheels make the rake cause I've never used it with out the wheels. But man I really like what the rake can do.
The hydraulic top link also makes the rake so much more useful or at least I should say easier to use. I drop the 3pt all the way and adjust the rake with the top link, angled down and it digs like a blade, tilted back where the tines barely touch I can leave a beautiful finish. The wheels are always on the ground.
Greg mentioned that the wheels prevent the rake from working aggressively, but that has not been my experience, in fact I'm amazed how much rough work my rake will do. I can dig in and pull piles of gravel/dirt and feather it off using the HTL spreading the pile, leaving it where I need it. or pulling it into a pile.
I really love my 72 inch land pride with gauge wheels. If I had to choose just one out of my 3 basic 3pt implements, between the rake, the box scraper or the rear blade, it would be the rake without a doubt.
And yeah, definitely get the wheels.
