In this case, the word "head" is an abbreviation for header. A header is the implement mounted to the front of a combine harvester to reap and gather the crop for threshing in the middle part of the machine. A row crop header is a header designed specifically for harvesting crops which are planted in individual rows. In the midwestern US, this is typically corn. A row crop header for harvesting corn can be seen in the related link below. I just randomly picked one brand of combine harvester -- no implication pro or con to the brand.
The 853 A is newer and more improved, than the 853. The size is the same, both are 8 row heads. this statement is wrong and 853 head is just made to combine corn but an 853 A can combine anything from corn to sunflowers but they are both 8 row heads. The 853 was the early version of an 8 row 30 inch row crop bean head. The 853A is the later version of the same head. The main difference was servicabilty. Both could also harvest sunflowers.

Wheat is generally not considered a row crop. Row crops are those which are somewhat dependent on having cultivation or tillage in the space between rows. This practice does not happen in wheat production, except perhaps in subsistence farming where the farmer must use hand labor for pest control.
The crop is located closer to the head. The crop has a thinner wall. The gizzard is more muscular and located posterior to the crop.

Two-row barley has two rows of kernels lined up vertically on the head of the plant, while six-row has six. Even though two-row barley has larger kernels, the six-row typically yields more at harvest.
If the kaingin is not burned after the harvest of the first crop, then the soil is not ready for the second season of planting. Kaingin depletes the soil of nutrients and fields can often only grow kaingin for a few seasons in a row.
