John Deere 1050 not running

Last weekend I purchased a John Deere 1050 tractor with loader. This is my first tractor of my own, however I grew up around farm equipment. After purchasing I flushed the transmission case and filled with fresh JD Hygard Low Viscosity oil, cleaned the filter screen, renewed the spin on, renewed the engine oil and filter, changed fuel filter and also changed the inner and outer air filters. I've put maybe 2 or 3 hours on the tractor in the last week bush hogging my pasture.

A few days ago while bush hogging the tractor was running normal and all of a sudden it blew out black smoke and drug itself down and died. It was similar to when your run through a particularly thick area of a field while bush hogging and the tractor momentarily drags down due to the increased load on the PTO, however in this instance I was not in a thick area at all and the engine drug itself down to 0 rpm and died. After the tractor initially died I was able to re-crank it a few times only at full throttle but it was running terribly and black smoking excessively, also knocking very loudly, not sure if its fuel knock or what.

I've checked the fuel system, the injectors are spraying a fine mist as would be expected. I also inspected both sides of the turbo and the fins are intact and the shaft spins freely. I pulled the valve cover and everything appears normal in there. The starter is no longer turning the engine over fast enough to crank it. I suspect that I've either burned up the starter trying to troubleshoot or something is bound up in the engine. Any ideas?
 
Doesn't sound good...

Have you taken an engine oil sample, cut open the filter?

Try removing any engine driven accessories, the belts, any hydraulic pumps. See if that helps it turn any easier.
