This page gathers the Barreiros tractors the register could not assign to a named range. Barreiros was founded in Madrid in 1954 and initially built its own diesel engines and trucks, adding tractors from the 1950s; in 1963 Chrysler took a stake in Barreiros and had fully absorbed the company by 1969, before its European operations passed to PSA Peugeot-Citroën in 1978. The range comprises the 4000 V, 4045, 5000 V, 5055, 70.70, 7000, R 335 types and the R 350, explicitly listed in the register as the narrow-track vineyard version.

The register lists here 8 versions with 26 to 52 kW, or 35 to 70 hp, mostly with Barreiros' own diesel engines.
Barreiros was one of the most important Spanish makers of commercial vehicles and tractors in the 1950s and 1960s and shaped the early motorisation of Spanish agriculture with its diesel engines, before the brand was absorbed under Chrysler and later further owners.
On these classics, the condition of the Barreiros diesel engine and the injection pump, rust on the frame and sheet metal, the function of clutch and mechanical gearbox, and on the vineyard versions additionally the condition of the narrow tyres and the steering count; spare parts today can only be sourced through specialist collectors of historic Spanish farm machinery.
