In the Littlest Higgs model with T-parity (LHT), top-partners (T{sub -}) are produced in pairs at the Large Hadron Collider (LHC). Each top-partner decays into a top quark (t) and the lightest T-odd gauge partner A{sub H}. We demonstrate reconstruction of the tt-bar system decaying hadronically and measurement of the top-partner mass from the m{sub T2} distribution. A top quark from a T{sub -} decay is polarized, and we discuss the effect of this polarization on the decay distributions.
