We present a summary of recent measurements utilizing top quark
candidate events extracted from approximately 110 pb-1 of p anti-p data
collected by the CDF and D0 experiments at the Tevatron collider.  We report
on a new combined Tevatron top quark mass of 174.3 +/- 5.1 GeV/c2 which takes
into account five separate measurements made by the two experiments.  We also
demonstrate how the techniques developed for the mass analysis have been
applied to further studies of the top quark and the tt-bar system.
