The 7.1-cent Tractor coil stamp, the 28th in the Transportation Series was issued February 6 in Sarasota, Florida by the U.S. Postal Service.

The 7.1-cent denomination represents the rate for third-class nonprofit mail which has been presorted by five-digit ZIP codes.

Ken Dallison of Indian River, Ontario, Canada, designed the Tractor stamp. His previous designs include the 11-cent Stutz Bearcat and 12-cent Stanley Steamer stamps in the Transportation Series, and the 33-cent Alfred Verville airmail stamp, all issued in 1985.

The Tractor stamp is being produced in unprecanceled and precanceled forms. The precanceled version includes the legend 'Nonprofit Org.' in two lines of black type. The design and the remaining lettering and numerals are dark red.

Tractors have a variety of uses, but the farm tractor is considered the most important because it revolutionized agricultural production in the United States.

With the advent in 1890 of the internal-combustion engine tractor (a word coined by combining parts of the words TRACtion and motTOR), huge areas of land were brought into production, crop yields were increased and acreage previously used to grow farm work-animal feed was converted to crops for human consumption.
