This old and rare Landini 40 HP hot bulb tractor with cooling tank. In the video you can see the tractor in action: in the field to start the engine, then plow the historical Baura (FE). Starting consists of heating the spherical cap in the head of a single-cylinder two-stroke engine, then moving the external flywheel to allow compression inside the cylinder and activation of combustion. The feature of this model is the cooling tank, it works by evaporation of water in contact with the cylinder. When the hood is very hot, a valve takes some of the water and mixes it with air and diesel to cool the hood. In 1932, Landini's rare 40 HP adventure film tested a raffreddamento vasca.
