Not without a very significant cost savings. I mean, near scrap value. A tractor can take a lot of water and be fine; but I wouldn't want to be chasing electric gremlins for a decade. I would also closely inspect everything. I wonder what kind of 'rehab' they did after the flood? Also, being in crates probably makes it worse, as they were lower than with wheel, and the crate trapped moisture/water. I would certainly want to build in enough cost savings to have an entire wire harness (that's a lot of money by itself), and maybe pull head to make sure the valves are salt water rust welded...
If we are talking $5k for a $35,000 machine; you probably could part it out and make money; but if we are at 50% original price, I would Run away
