i believe it was pulled by horses or mules then could have had tounge modifed to use with a tractor one thing for sure i dont think they could have graded very fast. these guys sure earned their money working this
A few years back when I did not have 100$ in my pocket,I saw a man buy at auction and begin torching one in as fine a condition.It gave me a sick feeling to see such a retired work horse be cut up.
