Anyone have this item from Howse? I am looking at buying one, but want to make sure it is worth the money. How good do they work? I basically want them to work up my garden before I till it. Garden is currently being used, but ground is hard enough by spring, that my 42 inch 3 pt tiller sheers pins trying to till it up. Thought maybe one of these might loosen soil then till. Any better ideas? thanks hjt
