We compute the dimension-2 condensate ⟨A²⟩ and dimension-4 mixed condensate ⟨q̄A\;q⟩ from the recent quenched lattice results for the quark propagator in the Landau gauge. We fit the lattice data to the Operator Product Expansion in the fiducial region 1.2 GeV≤Q≤3 GeV. Our result for the dynamical gluon mass at the scale of 10 GeV² is mA=600--650 MeV, in agreement with independent determinations. For the dimension-4 mixed Landau-gauge condensate we get αₛ⟨q̄gA\;q⟩=(-0.11±0.03) GeV⁴. This value is an order of magnitude larger than the ⟨G²⟩ gluon condensate.
