This is a 1960 International 660 Diesel tractor. It has 23.1X26 rear tires and 7.50X18 front tires. The tractor has power steering, PTO, a foot clutch, and an adjustable front axle. There is not a TA in this tractor, some came out that way. It has set in my shed for at leat 25 years. We used it some before that. Has a D282 international 6 cylinder engine that starts and runs good. The tractor serial number is 1770 S-Y and the engine serial number is D282 11116. This is a very straight tractor.
