  We use a light-cone approach to solve the Schwinger-Dyson equation for the
quark propagator. We show how this method can be used to solve the equation
beyond the space-like region, to which one is usually restricted with the usual
Euclidean-space approach. We work in the Landau gauge, and use an
infrared-enhanced model for the gluon propagator and include instanton effects
to get both confinement and vacuum condensates. With our models, reasonable
fits to known quantities are obtained, resulting in a light-cone quark
propagator that can be used for hadronic physics at all momentum transfers.
