International Harvester Model 1486 Tractor

This 1979 tractor was owned by Gerald McCathern of Hereford, Tex., who used it in his fields for 700 hours before driving it 1,800 miles to Washington, D.C., to participate in the 1979 American Agriculture Movement demonstration. As wagon master, McCathern coordinated tractorcades that, while bringing the desperate situation facing American farmers to the attention of Congress, also substantially slowed rush-hour traffic. In the midst of the protest, a large snowstorm nearly paralyzed the city, and farmers used their tractors to pull cars out of snowbanks, earning the goodwill of many people.
The American Agriculture Movement bought the tractor and presented it to the Smithsonian in 1986. The IH 1486 is representative of the technology that typifies modern agriculture. It has sixteen forward and eight reverse speeds, power steering and brakes, diesel turbocharged engine, wide adjustable front end, detachable front weights, air-conditioning, AM-FM radio tape deck, hydraulic adjustable seat, and an adjustable steering wheel.

I was in DC during the AAM event. I contributed to the fund that bought Gerald's 1486 IH tractor that was donated to the Museum. I was told that the tractor has been removed from the Smithsonian--If so-- where is it??
"thank you for the chance to coment on this great tractor. I have a 1976 1486 and it is a great performer. The international harvester co. was also a great place to work, I did so for sixteen years.
