Back in the 1980’s, brothers Mike, Gregg, and Don Tvetene were working at their family-owned Tvetene Turf Farms in Billings, Montana, USA. The business was faced with a critical labour shortage at the same time that it was experiencing huge demand for their turf. Out of necessity, the brothers conceived of an automatic turf harvester that could cut and stack sod using just one operator. Their biggest motivator, recalls Gregg, was the years of hard work they had put in stacking turf by hand on the family farm.
