Indicator Stick for Silos
Wisconsin farmer John Murphy designed an "Indicator Stick" for his silo which automatically signals when it's time to change doors for the unloader.
The stick attaches onto the unloader cable outside the silo, just above the winch, with a spring-loaded fastener.
As he lowers the unloader, the cable and the stick move up. Comparing stick height to a reference mark on the silo lets Murphy know how much the unloader's been lowered and when it's time to change doors. After changing doors, he simply pulls the stick down to start over.
The stick is marked in 1-ft. increments and will also fit on three-cable systems. Murphy sells his "Indicator Stick" for $12.
