Wheat is harvested either by hand with simple cutting tools or, more commonly today, by large machines called combine harvesters that cut the plants, separate the grain from the stalks, and collect the kernels for storage.

When wheat is ready

  • Wheat is harvested when the plants turn a uniform straw‑yellow color and the heads feel hard and prickly, with no green juice left in the stems.
  • At this stage the grain is dry enough to store but not so dry that it shatters and falls off during cutting.

Modern machine harvesting

  • On most commercial farms, a combine moves through the field cutting the wheat near the ground, feeding it into the machine.
  • Inside the combine, the heads are threshed to knock the kernels free, then cleaned so the grain goes into a storage tank while straw and chaff are blown out the back onto the field.

Traditional hand harvesting

  • In small or traditional systems, farmers cut the stalks with sickles, scythes, or similar blades, then gather and tie them into bundles called sheaves.
  • The sheaves are left to dry, then threshed (by beating or rubbing the heads) and winnowed so the light chaff blows away and the heavier kernels remain.

What happens after harvest

  • The collected wheat kernels are moved from the combine or from sacks into grain carts, trucks, or bins and then to elevators or on‑farm silos for longer‑term storage.
  • From there, the grain is cleaned further if needed and sent to mills, where it is ground into flour for bread, pasta, and many other foods.
