Not really. It is common to vary the number of tines depending on what stuff one is working on. If I have all the tines in my 6' rake, it lets very little through, and I have to stop the tractor frequently to clear it out unless I'm working on stuff an inch or less in diameter. I suppose you could start out by removing 2 of every 3 blades, for coarse dirt clod work, and go to an every other blade situation for finer work. I only use all tines when combing the driveway gravel - probably the optimal way to groom gravel or fine dirt (or a sand trap). That said, a long chain harrow will take large clods, and reduce them to graded dirt, in a pass or 2.
