In your June 2001 issue was a picture of an International Harvester implement: this is a one row cultivator pulled by one horse that went between rows of corn and other crops. The lever adjusted the width to fit between rows of crops. The two flat straps had a wooden handle that the operator controlled. I know — I used one back in 1935, 1936, and 1937 until my dad got a new tractor and two-row cultivator to use.
We also used this in potato fields too. You have a great magazine.Don Barnett
