Max Armstrong talks Big Bud, which was built in Montana to produce 760 hp, and it's a monster. Max talks about this big machine that was designed for a farm in California, then it went to Florida, then it returned to Montana and the Williams Brothers used it on their farm with an 80-foot cultivator. The tractor went into a museum in Iowa, but with new tires the tractor is back in the field.

Farm Progress America is a daily look at key issues in agriculture. It is produced and presented by Max Armstrong, veteran farm broadcaster and host of This Week in Agribusiness.
