A fruit juice extractor may include a load sensitive coupler coupling a drive motor to a drive shaft during normal operation, and decoupling the drive motor from the drive shaft when the fruit feed members become jammed. The extractor may also include a decoupling detector for detecting decoupling of the load sensitive coupler. The load sensitive coupler may include a rotatable drive hub rotatably carried by a drive shaft and connected to a drive motor, a fixed hub fixed to the drive shaft adjacent the rotatable drive hub, and a shear pin extending between the rotatable drive hub and the fixed hub. The shear pin may couple the rotatable drive hub and the fixed hub together during normal operation and shear to decouple the rotatable drive hub from the fixed hub when the fruit feed members become jammed.
