From what I have seen I would think it could be worth 2500 to 5000 dollars for the package. I would think the fact that it was your grandpas and you know what it has done and how it was cared for is worth alot. Just my thoughts, Merry Christmas!
What would a E in good shape with a 3 row narrow head and 10ft flex head be worth, it needs a bearing in the tranny other than that it needs nothing it combined 60 acres and didn't use a drop of oil.
