The new Precision Depth Roller is excellent! I wish it had been available twenty years ago when I bought the rototiller - it makes shallow tilling SO MUCH easier and a lot more accurate, with very consistent depth. I've always done a very shallow tilling of everything in the Spring, and sometimes to control weeds between the wide row beds all season. And I always use a shallow tilling to incorporate the cover crop that I seed in about 2,000 sq. ft. This is the perfect attachment for the tiller!
