FIG. 11.—REAPER PROVIDED WITH SEAT FOR THE RAKER.
Improvements upon the machines of Hussey and McCormick came thick and fast. One of the first improvements was to remove the grain from the platform in a better way. With the first machines a man followed the reaper (Fig. 9) and removed the grain with a rake. Then a seat was provided and the man sat (Fig. 11) on the reaper and raked off the grain. Finally the self-raking reaper was invented. In this machine, as it appeared in its completed form about 1865, the reel and rake were combined. The reel consisted of a number of revolving arms each of which carried a rake (Fig. 12). As the arms revolved they not only moved the standing grain toward the knife, but they also swept the platform and raked off the wheat in neat bunches ready to be bound into sheaves. So the self-raking reaper saved the labor of the man who raked the wheat from the platform.
Because it saved the labor of one man the self-raking reaper was for a time the king of reaping machines. But it did not remain king long, for soon there came into the harvest fields a reaper that saved the labor of several men. This was the self-binder. With the older machines, as the grain was raked off the platform it was gathered and bound into sheaves by men who followed the reaper, one reaper requiring the services of three or four or five human binders. With the self-binder (Fig. 13) the grain was gathered into sheaves and neatly tied without the aid of human hands. At first, wire was used in binding the sheaves but by 1880 most self-binders were using twine. So the self-binder saved the labor not only of the man who raked the grain from the platform but it saved the labor of all the binders as well.
The last step in the development of the reaper was taken when the complete harvester was invented. This machine cuts the standing grain, threshes it, winnows[13] it, and places it in sacks (Fig. 14). As this giant reaper travels over the field one sees on one side the cutting bar 15 to 25 feet in length slicing its way through the wheat, while on the other side of the machine streams of grain run into sacks which, as fast as they are filled, are hauled to the barn or to the nearest railway station. The complete harvester is either drawn by horses—30 or 40 in number—or by a powerful engine. It cuts and threshes 100 acres of wheat in a day and the cost is less than 50 cents an acre. It does as much work in a day as could have been done by a hundred men before the days of McCormick. Of all the wonderful machines used by farmers the most wonderful is the complete harvester, the latest and the greatest of reapers.
