Perhaps Tom Renner is best known for his outstanding John Deere 4WD Tractor collection, which includes rare WA-14 and WA-17 models, along with an outstanding 8020 complete with 8-bottom plow.

Numerous John Deere 4020 tractors will be on display during the Half Century of Progress to mark the 60th anniversary of the tractor that was in production for more than a decade.
