Organizers of the 10th anniversary Great Eastern Iowa Tractorcade said a record number of tractor owners brought their farm equipment to the joyride.
The organizers said 509 tractors registered for this year's 50-mile trek from the Dubuque County Fairgrounds to Dyersville, Iowa, and back again, an increase from last year's record breaking 450 tractors.
The parade, which began Monday and ends Wednesday, stretched for miles. The event attracts tractor fans from across the region.
"We tractor people are a different sort of club," said tractor owner Darold Sindt, of Keystone, Iowa. "For a lot of us, tractors are all we've ever done."
