This All-Crop combine changed the way the small grain was harvested on the small farms in the Midwest. These machines were developed in the early 1930s. We purchased our first Allis-Chalmers WC tractor with steel wheels in 1935 and the next year we bought our first model 60 combine. We went modern that year by putting rubber tires on the tractor and after many years of threshing with a Rumely Ideal thresher and a Rumely steam engine, this little combine was quite a change. This put us in a position to do our harvest when the grain was ready to harvest.

This machine had a five foot sickle and an eighteen bushel grain bin. It was driven by the power take off from the tractor. We used this first combine three years and then traded it in on a new model 60. In that three years I combined 1800 acres of grain with this small machine. That took a lot of driving. This combine had some construction faults, and after 1800 acres it was about worn out. We had a pickup attachment to thresh clover that had been windrowed and a recleaning attachment to clean the grain.

The grain went into the cylinder, then turned a ninety degree turn onto the straw rack. When we first saw one of these machines we did not think they would work with this ninety degree turn, but with proper adjustment they would thresh about any small grain. These combines were a far cry from the modern self-propelled machines we have today with ten to thirty foot headers and eight or twelve row corn heads.

With the rubber cylinder bars and rubber concaves, along with different sieves, about any grain could be harvested. I combined oats, wheat, rye, barley, timothy, alfalfa, red clover, buckwheat, great northern beans, soy beans, millet, blue grass and milo.
