We describe our recent NNLO QCD extraction of the top-quark pole mass from fits to experimental data on total inclusive and normalized (multi)-differential cross sections for ttˉ+X hadroproduction, using as input various modern PDF + αs(MZ) sets. We find top-quark mass values compatible among each other and with the PDG 2024 preferred value.
