I recently removed several trees from an area (about 1/3 acre) on my property which left it bumpy with lots of divots and depressions. I have a landscape rake and have used it to remove the top layer of grass/weeds and smooth out some of the areas needing attention, but the soil is hard-packed and even though I removed the stumps of the trees, there are still lots of buried roots. Which approach would be best to loosen the soil and give additional smoothing/proper soil condition for planting the seed? Harley rake? Tilling/leveling? Box blade with shanks? Some photos of the area are attached. BTW, I have an L3901.
