The race is on, only these vehicles are moving less than 25 mph

Unlike race cars that travel at speeds greater than 200 miles per hour racing for victory, farmers are racing to get their crops planted - but at a much slower pace.
As farmers move their equipment to and from fields, motorists need to be aware that slow-moving vehicles are on the road and traveling half the speed, said a Purdue University expert. Tractors and other farm equipment often weigh between 20,000 to 40,000 pounds and are two to three times the height of regular automobiles.
