The world’s largest tractor is sure to be a big attraction at the 2010 Farm Progress Show in Boone, Iowa next week.

The Big Bud 747 tractor was built in Havre, Montana by Ron Harmon and the crew of the Northern Manufacturing Company. Measuring 27 feet long, 20 feet wide, and 14 feet tall, and weighing in at 100,000 pounds, Big Bud can work more than one acre per minute, at speeds up to 8 mph. Except for its new paint job, chrome stacks, and a whopping 900 plus horsepower – the Big Bud looks like it did when it rolled out of the Northern Manufacturing Company building back in 1977.

Crop Production Services (CPS), Dyna-Gro Seed and Loveland Products Inc. will be featuring Big Bud to reinforce their “Think Big” theme for 2010.

Here’s a promo video of Big Bud:
