well Glad that works for you, but up my way so amny rocks and hard ass ground, , a pallet, even if wrapped in chain link fence, and lots of weight won't do anything
the advantage of a disc or other like tool is it loosens the soils making it easier for roots on SMALL seeds, they ask you in my opinion to firm up the top, so when it rains and such seeds don't get planted too deep more or less
I will say a pallet will clean an area of debris pretty well till it piles up
again, Glad that works for you, not bashing!
