For sale is this  Deutz F1M414. Called  "Elfer Deutz" in Germany referring to the 11 HP it had at the time the tractor was introduced. This is a very early model having only 3 speeds forward and no foot brakes.
Although it has an old patch to the motorblock this single cylinder water cooled tractor is in good running and driving condition as can be seen in the video. Extremely hard to find a 3 speed prewar model.
