Great machine, the 790! I'm sure you'll get many years of useful work out of her!
Those pictures are really nice...cool looking barn too!
BTW, be glad you got the ballast box. It really helps the 790 to dig into a dried out pile of materials. Buying a ballast box made a world of difference when I'm digging. Those big rear tires (filled) used to just spin. Now they push that bucket right in there.
You'll probably want a tooth bar though
