PNEG-2343 U-Trough Free Flow Unloading System 43
5. Power Requirements
Power requirements are dependent on the grain type, condition and moisture level. Power requirements
are suggestions and may vary in specific circumstances. Steps can be taken to reduce the power needed
to operate the unloader or sweep if the power available to the site is limited. Operating the unloader at a
slower speed and reducing the flow of grain into the unloader will reduce power requirements.
