About Killbros Products

What started in the 1950’s as a local producer of some small grain handling, continues today as the Killbros brand continues to add value to farming operations all over. In addition to the timeless tradition of orange grain boxes with blue gears, red and green Killbros grain carts and high-capacity wagons can now be seen across the countryside throughout harvest. The Killbros tradition of value and quality continues today in a wide variety of products.
