First of all, why do farmers even have to go into the bins?

Well, for one thing, the piled-up grain needs to periodically be leveled in order to maintain good air flow. Crusts and bridges that form on its surface also have to be broken up, plus grain that accumulates along the walls must be pulled down. Finally, when the grain is being removed from the bin, it needs to be pushed into an extraction auger.

Going into the bins and manually shoveling the grain is not only a hot and difficult job, it also poses risks such as getting trapped or buried in the grain, getting caught in the auger, and developing lung disease from breathing in grain dust.
