We report the measurements of the tt production cross section and of the top quark mass using 1.02  fb−1 of pp 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 σtt=8.3±1.0(stat)+2.0−1.5(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/c2 is derived from a likelihood fit incorporating reconstructed mass distributions representative of signal and background.
