After getting the flooring removed (finally) I started dragging dirt out with my little tractor.
That's when this happened.

I got to split my first tractor. Actually, went pretty well with a crain and a floor jack. Easier than pulling a car transmission to replace a clutch.
BTW, tractor has performed flawlessly since. Good thing; we really needed it in the next chapter.
