Which machine is used to gather cereal crops like wheat from fields?

The machine used to gather cereal crops like wheat from fields is the combine harvester. This machine is specifically designed to harvest grain crops efficiently. It operates by cutting the standing crop, separating the grain from the chaff, and collecting it into a storage tank—all in one continuous process. This multifunctionality makes the combine harvester particularly valuable for large-scale farming operations, where speed and efficiency are crucial.

While a tractor can assist in various agricultural tasks, including pulling machinery, it does not directly harvest crops. Similarly, a cultivator is used for soil preparation and does not have the capability to gather crops. The term “combiner,” while it might suggest a general harvesting function, does not specifically refer to the well-known combine harvester that performs the vital task of gathering cereal crops. Hence, the combine harvester is the correct choice because it serves the specific function of harvesting cereals effectively and efficiently.
