Dummy head

Dummy head

In agriculture, on a combine harvester machine, a dummy head or pick-up header features spring-tined pickups, usually attached to a heavy rubber belt. They are used for crops that have already been cut and placed in windrows or swaths. This is particularly useful in northern climates such as western Canada where swathing kills weeds resulting in a faster dry down.
