FIELD GUIDE
The story
The Chamberlain 40K was the first tractor manufactured in Western Australia, built from 1949. The models that followed it did a great deal of the work of opening up WA's agricultural regions after the Second World War – a period when the state was clearing and cropping country at enormous speed and needed machinery it did not have to import.
Carnamah has built one at five times the size.
The Giant Tractor stands on Yarra Street and is 11.5 metres high and 16 metres long, constructed from 42 tonnes of steel by DIAB Engineering in Geraldton and unveiled in 2024. It was funded largely by Tracmach along with private and corporate donations, which is to say the Wheatbelt paid for it rather than a tourism authority.
What lifts this above the general run of oversized farm machinery is the specificity. It is not a generic tractor. It is a scaled replica of a particular Western Australian machine, made by a Western Australian engineering firm, commemorating both the farming and the manufacturing side of the same story – the state made this tractor, and this tractor made the state's farmland.
It is also very new, which is a useful corrective to the idea that the Big Things belong to the 1960s and 70s. Towns are still building them, still funding them locally, and still choosing subjects that mean something specific to the district rather than something photogenic.
At 42 tonnes it is among the heaviest objects in the catalogue, and it is free to visit at any hour.

ACCESS
The World's Biggest Tractor stands on Yarra Street, Carnamah's main road through town (the same street as the BP roadhouse, which has documented large-rig/coach parking bays on both sides). Navigate to the Yarra Street site and park on or beside the street; no dedicated separate car park distinct from the street was confirmed, so this is treated as a legitimate main-street kerbside arrival rather than a hazardous stop, but a dedicated pull-off/turn-around has not been independently mapped.
