TRACTORS ON DISPLAY — The owners of more than 100 antique tractors brought their prized possessions to Discovery Park of America in 2017 for the first-ever Antique Tractor Show. They’re being asked to do it again this Saturday as Mahindra of Ken-Tenn sponsors the second annual event for what park officials are hoping is a bigger and better show. There is no cost for exhibitors to display their tractors. They are asked to arrive between 8 and 10 a.m. and be available for the tractor parade at 1 p.m. Tractor exhibitors will enjoy free admission for two. The tractor show is included with park membership and general admission will be reduced to $10 for all other guests.
