It was originally used on a sugar beet farm in Michigan's thumb. Dad bought it through our Cat dealer in Grand Rapids. The original rear wheels couldn't stand up to scraper duty and started cracking from the outside edges of the steel rims. The replacements (from Cat) were much heavier duty with the outer edges of the rims rolled over into a tube shape. The track bands have also been replaced with heavier duty ones than original.</p><p style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: #333333;">Brian</p><blockquote type="cite">On March 28, 2019 at 1:01 AM James Peck <<a href="mailto:jamesgpeck@hotmail.com">jamesgpeck@hotmail.com</a>> wrote:<br><br><br>Agco bought the Challenger line from Caterpillar in 2001.
