Joyce: The 140 was in production from 1958 to 1979, if you wish to check the year, get the serial number. It a metal tag rivited to left side of clutch housing. The actual serial number will be all numbers, either 3, 4 or 5 digit. There may be letters before and after the number, but those indicate options on that tractor. Then got to left of this page under research and info, click on serial numbers, then click on Farmall and International. This will give you beginning serial numbers for each year 140 was produced. Over the years the 140 used 4 different wiring systems. Once you have the serial number, I have the breakdown of serial numbers at which wiring changed each time. It went from 6 volt positive ground with a generator in 1958 to 12 volt negative ground with a alternator at the end of production in 1979. The 140 started off in 1958 with 40-60 serias type grill and styling. Those first ones were decaled with metal plated decals and were either Farmall or International. (International being the industrial model) In mid 1963 they changed to 04-06 type grill and styling, and the decals changed to adhesive type decals, and retaining the Farmall and International status. In 1968 the decals, ( still adhesive) changed again to International as the main hood side badge, gone was the small decal McCormick. From there onward the Farmall had the word Farmall in small print on the 140 model badge, all others were Industrial models. Your tractor must be a pre 1968 model as you mentioned the name McCormick. From the factory 140 could be equipped with standard U type drawbar or one point fast hitch. A good many of them have been converted to after market 3 point hitch. There were an assortment of implements and attachments built for use with 140. These included several different plows, 3-4 disks, half dozen mowers, cultivators of different configurations and dozens of different ground working tools, sidedressers, front snow blades, center and rear mount grader blades,etc. I'm sure I've missed some of them. If you have any question, come back.
