Digging up the yard

After my trip, and coming back to my house with a backyard full of weed, was more than I could handle. There were weeds growing everywhere. Apparently during my trip, there were plenty of rain which aid the growth of these nasty 'shrubs'. Currently bought a rototiller to help me with breaking up the ground and loosening the soil. A Craftsman 3hp 15" wide rototiller. Very temperamental but gets the job done. Here is how my backyard looks like now after putting in about 2 hours of work with the rototiller.
