About Us

AG Engineering & Development Co., Inc. was born in 1983 to manufacture, market, and distribute the Dammer Diker®, a patented reservoir tillage implement. 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. Quality and durability have become trademarks of the equipment designed and manufactured by AG Engineering.

AG Engineering is proud of its tradition and expertise in the development and production of quality agricultural implements. Call us today for help with your specific farming needs and requirements. Let our qualified personnel help you with your farming challenges.
