Top Quark Mass Measurement in All-Hadronic channel at CDF

We present the first Run 2 measurements of the top quark mass
in all-hadronic (all-jet) channel using top quark pair events
from proton-antiproton collisions at the Tevatron
and the CDF II detector. Top mass measurements in this channel
from both CDF and D0 in Run 1 received special attention
due to the fact that the measured top quark mass appeared to be
larger than that from dilepton and lepton+jets channel. Measurements
in this channel is very challenging because of the huge QCD multijet
backgrounds. We have nevertheless obtained precise measurements
in this channel using both template and matrix element methods.
Top mass results and comparisons with the other two channels
will be presented. The results are based on an integrated luminosity
of $1$ fb$^{-1}$ of $p\bar{p}$ collision data at a centre-of-mass
energy of $1.96$ TeV at the Tevatron collider at Fermilab.
