A hand operable juicer having a handle extending from beneath a juice receptacle is described. The handle has a drive link end that couples with a drive mechanism to rotate a drive shaft that extends up through a drive shaft conduit and couples with a pulping crown. Gear and crank type drive mechanisms are described. In some embodiments of the invention, the drive mechanism is configured to provide a rotational advantage, whereby a certain degree of rotation of the handle around the pulping crown rotational axis produces a higher degree of rotation of the pulping crown. The hand operable juicer described is easy to operate and easy to clean.
