Wishbone separator device for separating a wishbone from a poultry carcass, said wishbone comprising a hypocledium and two limbs, said hypocledium having an inward facing surface (2*), which device comprises: - a primary wishbone cutter, which is adapted to cut through the limbs of the wishbone and to separate the hypocledium from meat that is present adjacent to the inward facing surface (2*) of the hypocledium, - a secondary wishbone cutter which comprises: - two secondary wishbone knives, each adapted for separating the wishbone from meat that is present on the outside of a limb of the wishbone, and - a secondary wishbone knives actuator assembly, the secondary wishbone knives actuator assembly being adapted to prescribe a secondary cutting path for each of the secondary wishbone knives relative to the poultry carcass, each of said secondary cutting paths extending between a first position, in which said secondary wishbone knife is outside the poultry carcass and a second position, in which said secondary wishbone knife is arranged inside the poultry carcass, adjacent to the wishbone and outside of the limb of the wishbone, characterized in that the secondary wishbone knives actuator assembly has a small carcass mode and a large carcass mode, wherein the secondary cutting path that is prescribed when the secondary wishbone knives actuator assembly is in the small carcass mode differs from the secondary cutting path that is prescribed when the secondary wishbone knives actuator assembly is in the large carcass mode. which device comprises: - a primary wishbone cutter, which is adapted to cut through the limbs of the wishbone and to separate the hypocledium from meat that is present adjacent to the inward facing surface (2*) of the hypocledium, - a secondary wishbone cutter which comprises: - two secondary wishbone knives, each adapted for separating the wishbone from meat that is present on the outside of a limb of the wishbone, and - a secondary wishbone knives actuator assembly, - a primary wishbone cutter, which is adapted to cut through the limbs of the wishbone and to separate the hypocledium from meat that is present adjacent to the inward facing surface (2*) of the hypocledium, - a secondary wishbone cutter which comprises: - two secondary wishbone knives, each adapted for separating the wishbone from meat that is present on the outside of a limb of the wishbone, and - a secondary wishbone knives actuator assembly, - two secondary wishbone knives, each adapted for separating the wishbone from meat that is present on the outside of a limb of the wishbone, and - a secondary wishbone knives actuator assembly, the secondary wishbone knives actuator assembly being adapted to prescribe a secondary cutting path for each of the secondary wishbone knives relative to the poultry carcass, each of said secondary cutting paths extending between a first position, in which said secondary wishbone knife is outside the poultry carcass and a second position, in which said secondary wishbone knife is arranged inside the poultry carcass, adjacent to the wishbone and outside of the limb of the wishbone, characterized in that the secondary wishbone knives actuator assembly has a small carcass mode and a large carcass mode, wherein the secondary cutting path that is prescribed when the secondary wishbone knives actuator assembly is in the small carcass mode differs from the secondary cutting path that is prescribed when the secondary wishbone knives actuator assembly is in the large carcass mode.
