We report the measurements of the t (t) over bar production cross section and of the top quark mass using 1.02 fb(-1) of p (p) over bar data collected with the CDF II detector at the Fermilab Tevatron. We select events with six or more jets on which a number of kinematical requirements are imposed by means of a neural network algorithm. At least one of these jets must be identified as initiated by a b-quark candidate by the reconstruction of a secondary vertex. The cross section is measured to be sigma(t (t) over bar)=(8.3 +/- 1.0(stat) -1.5/+2.0 (syst) +/- 0.5(lumi)) pb, which is consistent with the standard model prediction. The top quark mass of (174.0 +/- 2.2(stat)+/- 4.8(syst)) GeV/c(2) is derived from a likelihood fit incorporating reconstructed mass distributions representative of signal and background.
