I just skimmed over the Jimna site, and a little info on their plows. If I read correctly, their 4-bottom plow had a 31.5 inch cutting width. That would be a little less than 8" per bottom. Hardly compares to a 12", 14", or 16" bottom we're used to with most "American made" plows. From the grainy picture I saw, they resemble "Scotch bottoms" that were popular YEARS ago for tuning sod. (Very narrow cut, easy pulling in sod) If so, their 4-bottom plow should pull something like a 2-bottom X 16" plow. Still hard to compare at that.
