After the split with Ford, Ferguson took the opportunity to have the Standard Motor Company of the UK produce a new design, the Model TE20. The model name came from Tractor, England but is affectionately known as the "Little Grey Fergie". There were several variants of the TE20; the first tractors were designated TE20 Using an imported Continental Z120 engine. In 1948 the TEA20 was introduced with a Standard brand petrol engine, following the introduction of the TED20 which ran on TVO (tractor vapourising oil, similar to paraffin). Later a diesel model was introduced, the TEF20. There were other variants with narrow wheelbases for working in vineyards and orchards, such as the TEB20 and TEC20.
