Abstract
A gearbox below a grain bin floor can have a shift coupling movable between a drive position and a neutral position. A control rod can be axially movable between a corresponding drive position and a corresponding neutral position. A pair of biasing members can be operably positioned between the control rod and the shift coupling to bias the shift coupling in opposite directions. The opposite biasing forces of the biasing members can act against each other to bias the control rod into the neutral positioning recess to retain the external shift coupling and the control rod in the neutral position and the corresponding neutral position, respectively. The opposite biasing force of the biasing members can bias the control rod into the drive positioning recess to retain the external shift coupling and the control rod in the drive position and the corresponding drive position, respectively.
