CHAPTER VI. 



THRESHING WITH A REGULARLY EQUIPPED 

 SEPARATOR. 



, HIS chapter will deal with the threshing of 

 those grains and seeds which may be suc- 

 cessfully handled by a regularly equipped 

 separator. It will include the threshing of 

 wheat, rye, oats, barley, flax, timothy, buck- 

 wheat, millet and speltz or emmer. Those 

 grains and seeds which cannot be threshed 

 successfully without some change in, or addition to a regu- 

 larly equipped separator will be treated separately in the 

 following chapter. 



Headed Grain. The bulk of the grain grown at the 

 present time is cut by binders and is delivered to the thresh- 

 ing machine in bundles. There are localities, however, in 

 which all, or nearly all, the grain is cut by headers and 

 delivered to the separator loose. Bound grain is supposed to 

 be fed to the cylinder, "heads first/' and when so fed, the 

 work of the cylinder is made easy as the straw holds the 

 heads while the grain is being knocked out of them. This 

 cannot be the case with headed grain, as usually but little 

 straw is left on the heads, because, to keep the bulk small, 

 the header is run to cut only low enough to get most of 

 the heads. Other things being equal, headed grain is, then,
