We report a measurement of the tt production cross section using the CDF II detector at the Fermilab Tevatron. The analysis is performed using 311 pb{sup -1} of pp collisions at {radical}(s)=1.96 TeV. The data consist of events selected with six or more hadronic jets with additional kinematic requirements. At least one of these jets must be identified as a b-quark jet by the reconstruction of a secondary vertex. The cross section is measured to be {sigma}{sub tt}=7.5{+-}2.1(stat.){sub -2.2}{sup +3.3}(syst.){sub -0.4}{sup +0.5}(lumi.) pb, which is consistent with the standard model prediction.
