An ear lifter for crops with a support bar, wherein the support bar extends in a main direction of extension and has, arranged one after the other in the main direction of extension, a fastening portion, a middle portion and a skid portion, wherein the support bar has a restraining device extending along the middle portion,
wherein the restraining device reinforces the middle portion with respect to a bending stress, wherein a stiffening effect of the restraining device is greater in a first bending direction than in a second bending direction opposite to the first bending direction,
wherein the restraining device includes a stiffening plate extending substantially parallel to the middle portion of the support bar, the stiffening plate having a first end rigidly fixed to the middle portion of the support bar and a second, opposite end having a first stop which engages a second stop provided on the support bar to restrict relative movement of the support bar to a greater degree in the first bending direction than in the second bending direction.
