The top row, a Minneapolis-Moline tractor. Possibly an "R" model...?? Should be a tag on it somewhere. Those fenders look to be in decent shape yet, and worth a few bucks to the right person. Grill looks OK too... Worth way more than scrap, for those pieces.
Second row, a forage harvester, and thresher. Forage harvester almost looks like an A-C with the faded Persian Orange paint... Tag should tell you, if there is one. Thresher resembles a "Bell City". IH's early line of threshers. If you Google Bell City Thresher, there is a youtube video of a fellow threshing wheat, belted up to a Massey 44 Standard tread... It may be worth a few bucks to the right guy too, for some parts.
Third row, looks to be the remanants of a pull type combine. And believe I it looks like the beaters on a manure spreader at the bottom right.
