McCormick Tractor Potato planter No.3 2-row, fully automatic, for tractor number of copies and construction period unknown, France and Germany Information The 2-row potato planter No.3 was pulled by a tractor. However, the drive did not take place via the pto shaft, but via the wheels of the planting machine. This principle was the same as that of the one rider pulled by the horse. These potato growers were built by Harvester in both France and Germany. The machine was equipped with two correctors.

The seed potatoes were in the large container and were brought up one by one by means of a chain with spoons. At the top, the seed potato fell down on the other side and in this way all the seed potatoes came into the ground at a regular distance from each other.

A sensor or tumbler was used to check whether a seed potato came up. If this was not the case, the mechanism came into effect. The operation of the planting machine was done by a second person who rode on the machine. This set the height and also ensured that the two corrector discs remained filled with seed potatoes.
