I've been thinking about this, just trying to figure out how "we" might effectively accomplish this, in a perennial clover plot, without doing too much damage to the clover, but yet optimize our over seeding. I think maybe something like this, with 50% less tines might work. 50% less tines to help keep the "trash" from building up too much. I'm going to keep a look out for one of these (we all need more equipment, right?) and maybe play around with it.
