The event at the Wood County Fairgrounds draws tens of thousands of fans every year, according to organizers, the Northwestern Ohio Tractor Pullers Association.
Multiple divisions divide the pulls into different classes of tractors, from the smallest kiddie-pull class through Super Semis, with a maximum allowed weight of 20,000 pounds.
Plenty of weekend events at the championships are designed to entertain young and old fans, such as the National Kiddie Tractor Pedal Pull open to children, 3-10 years old and a scale pullers competition of remote-controlled scale pulling vehicles on their own dirt track.
A retired tractor museum gives fans a chance to examine relics of the past.
Tickets are $110 for adults for a three-day pass and $250 for adults for a camping pass. Children under 10 get in free.
Spectators are limited to one cooler no larger than 12-by-12-by-12-inches. No firearms, fireworks or any items restricted by local, state or federal law will be allowed on the premises.
