[AT] [Farmall] Super M Fan Belt -- and other fun stuff

[charlie hill]

I agree with you that the gauge is probably close to right for no other 
reason than a bad gauge would more likely read low than high.  I just 
figured it was the only variable we hadn't discussed, why leave it out.

It'll be interesting to know how it does.
