Slow progress tilling the garden

As the title indicates, I've made a little more progress tilling the soil for the side garden.  It's slow going.  I think it's a combination of things: we haven't had a good "soaking rain" in a while, I'm using a front-tine tiller, the soil almost certainly hasn't been turned over in many years, I'm tired. 

Regardless, I think I'm around 70% finished with the task.
