Along with Loftness, there are Flexi-Grain Storage systems from Richiger and Delta Grain Bags Systems. All feature bags attached to a half-circle-shaped bagger, which is attached to a tractor. Grain is fed to the bagger either from a grain cart or combine auger, or from a truck that dumps grain onto a pan, which augers the grain into the bagger.

As the grain is moved forward into the bag by the compression auger, it gradually pushes against the bag's walls. The bag in turn opposes resistance, and the appropriate balance of pressure and tension is attained by properly regulating brake action on the bagger.

Meanwhile, the tractor is in neutral with the PTO engaged. As the bag fills, the bagger slowly moves. When the bag is full, it is sealed airtight with 2 x 4 boards bolted together. The seal 

keeps the well-packed grain dry until it’s removed.

“Of course, bags need to be on a flat surface,” says Joel. “During the storage period, you need to monitor the bags weekly to check for any potential animal damage. If the bag is punctured, it will likely seal itself from pressure from the grain. The grain is completely sealed and protected from insect damage.”

Grain is removed by unsealing the bag and attaching it to the unloader. It is augered into semitrailer grain beds. “It is completely free of insect damage and eggs,” says Joel. “It is the same quality as when it went in.”
