Standard-tread tractorReference
Built in Geelong, AustraliaReference
The AW-7 models were a unique Australian evolution of the earlier AW-6 models. The AW-7 was the standard tread version of the Farmall AM-7 and a cousin to the US-built International W-400 and British-built McCormick International B-450. There were two models, the AW-7 diesel and AW-7 kerosene. The AW-7 diesel was sometimes called the "AWD-7", although this was not the official name.Reference
