The farmer does not stand so much in need of new tools as of power to run the tools that he has. I have followed many a weary mile behind a plough and I know all the drudgery of it. What a waste it is for a human being to spend hours and days behind a slowly moving team of horses when in the same time a tractor could do six times as much work! It is no wonder that, doing everything slowly and by hand, the average farmer has not been able to earn more than a bare living while farm products are never as plentiful and cheap as they ought to be.
As in the automobile, we wanted power—not weight. The weight idea was firmly fixed in the minds of tractor makers. It was thought that excess weight meant excess pulling power—that the machine could not grip unless it were heavy. And this in spite of the fact that a cat has not much weight and is a pretty good climber. I have already set out my ideas on weight. The only kind of tractor that I thought worth working on was one that would be light, strong, and so simple that any one could run it. Also it had to be so cheap that any one could buy it. With these ends in view, we worked for nearly fifteen years on a design and spent some millions of dollars in experiments. We followed exactly the same course as with the automobile. Each part had to be as strong as it was possible to make it, the parts had to be few in number, and the whole had to admit of quantity production. We had some thought that perhaps the automobile engine might be used and we conducted a few experiments with it. But finally we became convinced that the kind of tractor we wanted and the automobile had practically nothing in common. It was the intention from the beginning that the tractor should be made as a separate undertaking from the automobile and in a distinct plant. No plant is big enough to make two articles.
The automobile is designed to carry; the tractor is designed to pull—to climb. And that difference in function made all the difference in the world in construction. The hard problem was to get bearings that would stand up against the heavy pull. We finally got them and a construction
