manufacturing
A couple of weeks ago, my brother-in-law, Ron gave his dad, my father-in-law a calendar from 2012 that he had used at work…not for the calendar but for the pictures. They were all pictures of tractors through the years. We all took a look at that calendar, because it was interesting to see how much tractors had changed over the years, and the different makes for that matter. I remember seeing one that could have easily passed for a travel trailer, were it not for the tractor wheels. And there were makes that even my father-in-law hadn’t heard of, and having grown up on ranches, I would have expected that he would know them all.
Since the Industrial Revolution, which occurred from 1760 to somewhere between 1820 and 1840, when manufacturing transitioned from hand production to machines, technology never stops changing. There are always new ideas, and someone to invent them. I recalled seeing a couple of pictures among the old pictures I have been going through, that showed a couple of different tractors used by members of Bob’s and my families. Even though these pictures probably weren’t taken that far apart in years, the two tractors are very different from one another. I suppose that the tractors themselves could have been much different in age, since you often use a machine for many years before it wears out, and they could have been for different work, thereby requiring different designs, but I was struck, nevertheless, by the vast difference in their design. My father-in-law also told me that it could depend on the area of the country, as to what makes of tractor were available. That makes sense too, in that different climates, and growing seasons might require different types of wheels and designs. I suppose that humidity could play a part in 
how the engines ran as well, and so could affect what tractor make would work better in those areas.
Technology is changing so fast these days that tractors may one day be obsolete, you never know. I mean…who ever thought there would be a vacuum cleaner that cleaned by itself, and yet now we have them. I don’t mean to say that crops will ever harvest themselves, or that the ground will just stay plowed, but one day there might be a machine that does those jobs with just a little bit of programing. Then, like the Roomba, which is no longer called a vacuum, the tractor might change its name with the modern advancement of automation too.
