[AJD] sparkplugs- problem - failures - maintenance - new technology

[astroguy at nas.com]

Seems like a lot of problems with JD tractors, comes from troublesome
sparkplugs.

So my questions are:  

1)     Why do spark plugs go bad?

2)     Why do spark plugs go bad so fast in JD tractors?

3)     Is there a way to do some kind of preventive maintenance for plugs?

4)     Are there new technology sparkplugs that eliminate the need to
purchaseng new plugs ever year? Bosche now produces Platinum Ir Fusion
plugs made up of platinum and Iridium.  Reading the literature, sounds like
a great spark plug.  

Any thoughts??

Thanks, Kreig
