The 27,500 square foot corporate office and manufacturing facility is located in Kennewick, Washington in the heart of Columbia River Basin agriculture. The Dammer Diker, which was developed and patented by company President, Thayne B. Wiser, is manufactured and distributed worldwide by AG Engineering. Innovations with the Dammer Diker®, primarily the hydraulic reset shank, have led to the custom design and manufacture of a number of tillage and ground working implements.
