1946 hand-built trenching machine - video
Hand-built trenching machine. The machine can dig a trench 8 feet deep and 10 inches wide and, depending on the soil, could advance itself at a rate of 15 to 20 feet per hour. The trencher was restored to working condition in 2003 and is now housed at the Pioneer Acres Museum in Irricana, Alberta.
