A measurement of the top quark mass (Mtop) in the
all-hadronic decay channel is presented. It uses 5.8 fb−1 of
data collected with the CDF II detector at the Fermilab Tevatron
Collider. Events with six to eight jets are selected by a neural
network algorithm and by the requirement that at least one of the
jets is tagged as a b-quark jet. The measurement is performed with a
likelihood fit technique, which simultaneously determines Mtop and
the jet energy scale (JES) calibration. The fit yields a value of
Mtop=172.5±1.4(stat)±1.0(JES)±1.1(syst) GeV/c2.
