Another interesting piece of technology I checked out at the 2019 COFS was the Saskatchewan built X-Steam-inator. This device promises to clear away weeds using a PTO driven generator and, from what I recall, about 2 gallons of water per acre.
At this point I was uncertain about ground speeds. But, the concept is interesting. Can we use a mechanical device instead of chemicals to get some of the harder to control weeds, either early in the season or mid-season?
Time will tell. The machine is still a prototype at this point with product rollout expected in 2020. For more information they have a limited website at http://www.xsteaminator.com
