WHY ARE YOU SHOUTING AT ME?  <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D -->  I've searched here and at yesterday's tractor and at tractorforum.com. and found nothing.  We have been looking for the answer to this question for some time now. I figured this was where the Oliver experts were so I posted the question here after alot of searching. The closest thing to an answer is what Jason Epperson stated earlier. I guess it will have to remain a mystery for now.
Thanks <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->
