Did you notice that the text it is a link, and did you click on it? If not you should, as you will get more details.Interesting, thanks. Not sure what that is....must be something from the 70s that made people think good things about our planet. You know like no cow flatulence and such.
Bill - if you're not convinced that HVC is Home Vehicle Compliant then you could spend some time looking thru the IH archives at this link. Let us know if you find something. Lots of production info located here.I've seen the HVC used on other models as well. Such as the 682. I'm not really convinced on the explanation.
