Overview & History
Built from 1969 to 1971, the Fiat 650 tractor was one of the models made by the Italian manufacturer under the OM (Officine Macciniche) logo. It was made in two-wheel- and four-wheel-drive versions.

Equipped with a 3.7-liter 3-cylinder diesel engine that produces 65 hp, the Fiat 650 is one of the more powerful Fiat tractors of its time. Its engine also has a liquid cooling system to prevent it from breaking down in hot temperatures. Its bore and stroke are 110 x 130 mm, allowing it to run more efficiently. With a rated RPM of 2200, the Fiat 650 can easily run under load.
The Fiat 650’s rear lift has a maximum capacity of 2,100 kgs, making it perfect for pulling or carrying heavy equipment. It has 7 forward and 2 reverse, and goes up to 24.9 kph with the 7th gear and 11.8 kph with the 2nd reverse gear when equipped with size 12-36 rear tyres. Its rear PTO can run at 540 RPM.
The standard front tyres for the 2WD variant are sized 7.50-18 and 9.50-24 for the 4WD variant. Meanwhile, both variants’ standard rear tyres are sized 13.6-36.
The 650 weighs 2,874 kg. It is 376 cm long and 176 cm wide with a 231 cm wheelbase. It has a height of 173 cm up to the steering wheel and 151 cm up to the hood. The Fiat 650 is a reliable workhorse and one of the most balanced tractors that Fiat has made.
