Every time a delicious kernel of corn passes your lips or you crunch into a slice of crusty, freshly-baked bread, you can thank a farmer. According to the US Department of Agriculture, farming and food-related industries contributed about $1.3 trillion to America’s gross domestic product in 2021.

It’s not a stretch to say that agriculture is critical to our lives, as is the machinery that prepares the land, plants and fertilizes the seed, precisely pulls the weeds, and harvests it all. From its inception in 1837, John Deere started by manufacturing a steel plow and has evolved into a modern company producing highly technical equipment. But beyond making farming vehicles like combines and tractors, the Illinois-based company also manufactures heavy construction and forestry machines such as motor graders, dump trucks, and skidders.

Correction: This article has been updated to clarify that the equipment made at the Davenport, Iowa facility is for construction, not farming. Additionally, a dump truck originally identified at a 410 P-Tier has been updated to be correctly described as a 310 P-Tier.
