This tractor sprayer that you will see in action in the video below was custom built by Terry Miller and Scott Anderson for Miller Research, based in Rupert, Idaho.
The company says the sprayer “is great for applying chemical to our research plots. This video shows the many features of our spray tractors, as well as how we calibrate for our sprays.”
The tractor can hold twelve tanks for twelve different treatments. Each slot has a magnet that agitates the product in the tank.
