Description: |
In the 1940s, Ed Malzahn wanted to replace the pick and shovel work needed to install residential utility services. Trench digging was slow using a hand shovel and expensive using a large trencher. Malzahn invented the DWP Trencher, which was patented in 1955. The DWP Trencher had two-piece buckets spaced 4" and a digging depth of 24" and moved on a welded frame with four wheels and pneumatic rubber tires. It provided an intermediate digging solution by digging trenches faster with an affordable mechanized process. The DWP trencher has evolved into today’s Ditch Witch, which is used in trenching for all underground utilities, including television, internet, telephone, plumbing, and electrical services. |
