[AT] Heat treating tractor parts

[Thomas O. Mehrkam]

Heat treating will make them harder. It will also make them more 
brittle. That may not be what you want. Will they be subject to wear?

I am an electrical engineer so I should not be giving advice on this 
subject. If you know the load and tell me something about the 
application I work next door to a Mechanical Engineer. I can probably 
get some good advice from him.
