Farmers looking to reduce soybean loss during harvest should run their combines at slower speeds.

That from Harvey Chorney, Vice President of Manitoba Operations with the Prairie Agricultural Machinery Institute (PAMI).

Studies have shown losses of up to two bushels per acre at higher speeds.

Chorney notes anything above five miles per hour showed significant loss at the header.

"That was due to the fact that air reel or not, you got ahead of your cutting knife and you were leaving beans behind," he said. "The bottom pods weren't being cut and fed into the header."

However, Chorney added it is possible to go too slow as the combine can lose its inertia, causing more soybeans to fall to the ground.
