Ok, I'm not sure the best way to do this, but I have an area with quite a few trees, one every 12' or so, that's about 150' x 100'. I'm looking to limb the trees up to about 8' and plant grass seed and fence it off as a dog area. I need to clear the weeds, and remove a couple inches of pine needles and start removing rocks so I can ride the mower around once the grass grows up a bit. It's a fairly flat area, although rutted, and lots of golf ball sized rocks. I was thinking about a 4' square of chain link fence wrapped around some heavy timber and drag it behind the BX. Having never "tilled any soil" I have no idea what works. I know I'll probably have to pick out rocks by hand with a rake. The goal is to make a secure fenced off area for our one very old dog and a couple new pups so they are safe if left outside. Not looking to feed the local wolf, bear , and coyote population. Sorry to be so long winded, just looking for ideas to level and smooth a really tight area.
