chopper area, sheetmetal for cracks around the bearings and housing, also check the sheetmetal around the area where the walkers are, if the chopper goes out of balance, that area is stressed and vibrated really bad. variable speed cylinder adjustment, the top pulley with the chain coming from the top shaft and going to the bottom pulley, that sprocket with two sets of teeth has a tendency to wear on the inside, that is easy to replace, but make sure it hasn't worn too bad on the pulley itself. walkers and sieves will tell a lot about what the combine has harvested and what was run through it. if they are all beat up, even unrepairable sometimes, it's best to walk away. most of them can be straightened though. the 6600 was a decent machine, if it can be had for the right price (probably around $8k for all in your case) then go at it. good luck
