Modern power units and corn harvest have brought both increased speed of harvest and greater choice in harvest methods. Corn picker-huskers, both pull type and tractor mounted, are made in one- and two-row sizes. Corn picker-shellers are made in one- and two-row sizes with some adapter sheller components to be used with the picker-husker basic machine. Lastly, the large combine, pull type or self-propelled, has been fitted with gathering points for the corn crop and can be used (with reduced cylinder speeds) for a picker-sheller. In two out of the three above instances, it is possible to combine two operations in one. This is a definite trend in harvest machinery. These self-propelled combines have been fitted with 2-row, 4-row, and in a few cases, 6-row gathering heads. Corn harvest, for a given farm, can now be accomplished in a very short time, and if done early in the season the corn will have a high moisture content. It can also be shelled in the field and go into weather-tight, rodent-proof structures for storage (provided that moisture is reduced). The shelled corn is a more suitable form for mechanized feed handling machinery to meter and deliver to the feed bunk.
