Oil analysis interpretation , to buy wheel loader help?

I am looking at buying a John Deere 544h With 16000 hrs on it. The machine came out of TX its fairly tight, no corrosion pretty clean. The price is not horribly bad but not a steal by any means. Only problem I did an oil analysis as it appeared that the fluids have not been changed in a long while. I was worried the Tranny and motor might have problems because the tranny fluid was pretty thick and old looking and the oil was pretty black so I sent off samples. I ran the machine pretty hard for 20 minutes then I took the oil samples by pulling the filters off wiping them of good and dumping oil from the filters into canisters for the oil lab. I got the results back and I have no clue on how to read them and the lab cannot tell me levels that are typically good, bad, worn, or failure imminent. So does anyone have opinions. I have read numbers all over the place and I realize I am buying a used machine but Id like to know if this is typically indicative of immediate engine failure within the near future or down the line.
