Here we take a look at buying used McCormick XTX tractors, focusing mainly on the Italian-built XTX145, XTX165 and later XTX185 simply because these are now the most readily available. We also touch on the higher powered XTX185, XTX200 and XTX215, which subsequently morphed into the TTX series when their production switched from Doncaster in the UK to Italy in 2008
