Annual Maintenance Recommendations

All proper safety precautions should be taken by all personnel who perform maintenance and repairs on elevated seed houses.

 
  • Clean out all seed.

  • Clean hopper panels to remove seed oil. Many gins report good results with steam cleaning. 

  • Make the hopper surfaces smooth again! Many gins report good results with a sander or steel brush.

  • Examine for stress fractures and loose hardware. Repair or replace as necessary.

  • Remove rust and corrosion.

  • Add proper guards or fall protection devices on exterior inspection ladders.

  • Post decals “DANGER - DO NOT ENTER AREA BELOW HOPPER DOORS WHEN SEED IS IN STORAGE HOUSE.” Decals are available at no charge from Cliff Granberry Corp.

  • Add Hopper Conversion Kit if the seed house is in reasonably good condition.

  • If repairs are too extensive, replace with new Elevated Seed House.
