They designed a single bottom rollover plow to fit on the Ford tractor with the Ferguson Hitch. Ferguson bought some which worked so well, that he gave Lindemans a contract for 10,000. They would load a truck or rail car, get the bill of lading, take it to the bank, getting $18.60 for every one shipped. This made a profit of $8.00 per plow.
This was a very unique plow for the day because when you got to the end of the row there was nothing to trip or do but raise it out of the ground and turn around. When you raised the plow it would trip a lever and the weight of the plow would allow it to turn over, locking it into place when you set it down. The first model had two coulters, the second model was designed with a single coulter that was attached with an adjustable casting. The third model was a big change, with its cast top link, frame and trip arm.
