We have developed a new event generator SUSYSM to simulate the production of squarks and gluinos at hadron supercolliders including all the cascade decays as given by the minimal supersymmetric model. The simulation incorporates final-state hadronization and fragmentation effects for the decays of heavy flavors. We have used this to compute the rates for {ital E}{sub {ital T}} events, same-sign dilepton events, {ital n}{sub {ital l}}=3, 4, and 5 isolated-lepton events, and single or double {ital Z}{sup 0}+{ital E}{sub {ital T}} events from squark and gluino production at the CERN Large Hadron Collider (LHC) and the Superconducting Super Collider (SSC) for cuts inspired by the Solenoidal Detector Collaboration. We have identified and estimated several backgrounds to the various event topologies and shown that it should be possible to extract signals in several channels both at the LHC and SSC. We have shown that after accumulating one year's worth of design luminosity, it should be possible to identify a gluino with mass up to 2 TeV at the SSC, while the corresponding reach of the LHC is 1.2--1.7 TeV, depending on the luminosity.
