I just posted a pic of my backyard on the thread about How much time....
Tilling and plane work I do with both the 749 and a 4520 tractor so I can do the work pretty fast.
Living in the Rocky Mountains you never get rid of all the rocks, you just learn to deal with them. If you till the ground deep enough you can generally push them down out of the way when rolling. there are some jobs where I have to run a rock bucket to get the big stuff out of the way though.
