Have you ever stopped to think about how Caterpillar make such big tractors? Where do they start? What does the factory look like? How do the people who build the equipment move the huge pieces? How do they test it when it is done?
If you have ever wondered where Caterpillar machines come from, then a visit to www.howstuffworks.com/cat-tractor.htm will be fascinating! You will travel to a Caterpillar factory in DeKalb, IL, where Caterpillar Agricultural Products assembles gigantic Challenger agricultural tractors that weigh up to 40,000 pounds.
These tractors are used by farmers around the world, as well as on some construction sites. A great PR excercise by Caterpillar no doubt but lots of engineering and some cool videos in here too.
