If you can get it to run it should bring something in the $1,500 - 2,000 range. Bad thing I can see is the exhaust is gone, which probably means the flange on the exhaust manifold is gone too, that is pretty common on those, exhaust manifolds are pricey for that model, ouch!!!! I have one about like it that is equipt with an Oliver Heil 6 way mech bulldozer. You shouldn't scrap it!
Have a great day!!!
