Industrial, commercial, and agricultural industries all have one thing in common--they depend on diesel-powered equipment to get the job done. In the agricultural world, diesel is just as much a necessity as the food we need to survive, so the two of them go hand in hand. The World Ag Expo drives this point home year after year, as the latest and greatest in diesel engines, equipment, fuel, and emissions are showcased to both farmers and the general public.
With more than 2.5 million square feet for exhibitors to display and spectators to roam, the World Ag Expo is the SEMA show for America's working class. Some of the biggest names in the world were on hand, including Caterpillar, John Deere, Case IH, Takeuchi, New Holland, Bobcat, Cummins, Allison, Peterbilt, General Motors, Dodge, and Ford. In addition, some familiar aftermarket companies like Gale Banks Engineering, Performance Diesel Inc., and BD Diesel had booths full of products for sale.
Realistically, it would take days to see everything this event had to offer. The fact that six-page maps of the grounds were handed to every entrant gives you a sense of how massive the World Ag Expo really is. Here's a look at what we came across in a jam-packed day of browsing around the largest agricultural show we'd ever attended.
 Conveniently located near...  Conveniently located near its C18 ACERT-powered Challenger sat this massive C18 engine. This version boasted 575 hp at 1,800 rpm. |  While making our way through...  While making our way through the tractor trailer section of the expo, we discovered this Peterbilt pickup truck. It was powered by a 6.7L Paccar (PX-6) inline-six engine, which, depending on the version, can make between 200 and 325 hp. |  An 8-foot bed and storage...  An 8-foot bed and storage compartments also accompanied an already unique truck. We think Peterbilt should mass produce them! |
 As if Cat hasn't solidified...  As if Cat hasn't solidified its brawniness in the off-highway industry enough, its axleshaft specifications from an MT900B model Challenger were on display (left) next to two of its biggest competitors. Team yellow's axleshaft diameter came in at 5.7 inches versus 4.7 and 4.5. |  It was obvious that the EPA's...  It was obvious that the EPA's non-road diesel emissions rules have led to cleaner-burning engines in agricultural equipment. One manufacturer proud of its ability to create clean diesel technology was Massy Ferguson, which posted this sign next to one of its 8680 model tractors. It claims its 8600 series tractors are the first in the world to feature selective catalytic reduction (SCR). |  Several generator sets were...  Several generator sets were on display from Cummins, including this QSX-15 engine. According to Cummins, it meets Tier III emissions standards and makes 510 hp. |
