In Mexico, the transfer of agricultural technology has been a process hampered for several reasons, due to which subsistence agriculture was dependent on animal traction and human power. Despite the introduction of tractors and harvesters that have been imported and in some cases assembled in the country, with a percentage of domestic components, their adoption has been exploited only in medium and large-sized agricultural enterprises by farmers engaged in commercial agriculture, neglecting smallholders. Mexico is a major exporter of tractors in the segment of medium power and a leader in the automotive industry, but the country has high levels of poverty with low productivity in agriculture. The country can become a leader in the manufacture of tractors in the segments of low power, harvesters and power tillers. Manufacturing industry of these goods should not be treated as a separate sector, as has happened to date, but should be integrated into the automotive industry. If low power tractors, tractor powered harvesters and power tillers are made available at affordable prices for small land holders, it can contribute immensely in agricultural growth in the country and would reduce rural poverty. In this paper current status of the assembly of tractors, harvesters and automotive industry in Mexico is detailed, finally discussing the objective of integration of these industries and its benefits for the agricultural and manufacturing sector.
