As U.S. farmers benefit from the boom in commodity prices and report rising incomes, they are looking to invest in new farm equipment so they can better handle their upcoming harvests. However, they often have to wait longer for their tractors and other equipment as demand is outpacing supply.

At the 56th annual Iowa Power Farming Show in Des Moines, Iowa, farmers from around the state gathered to look at the latest in farm equipment offerings from companies like John Deere. "Five years ago, a new tractor could be delivered in a couple of months," Dan Seitsinger, a sales representative for Van Wall Equipment, told the Des Moines Register. "This year, if you order today, we can get it delivered by September."

Strong demand from farmers has put pressure on farm equipment manufacturers to increase their output, but the demand has so far eclipsed supply. Daryl Aspersen, a farmer from Wisconsin who traveled to the expo, said that he was looking into purchasing a John Deere 8225R model tractor because "last year was my best in 38 years of farming."

"There's just too much profit in corn right now," he affirmed, declaring that he planned to grow 400 acres of corn on his farm, instead of rotating with soybeans as he usually does. This year's event attracted 19,000 visitors.
