That's hilarious! Who built the thing, do you suppose?
Aha, a quick Gurgle search revealed:
Agrifull was a Brand of Toselli an Italian Crawler tractor manufacturer. The Company only lasted a few years till 1977 when the Fiat group of Italy took them over.
The company offered a complete range of agricultural machinery from Balers to wheeled tractors built by Toselli. The tractors were from 30 hp to 115 hp, powered by VM air-cooled diesels. Toselli became Fiat's specialist tractor division.[You must be registered and logged in to see this link.]
Of course they were owned by Fiat. In Italy, who else?
