The present invention relates to an oil cooling apparatus for hydrostatic transmissions that includes a cooling main body coupled to a transmission case; an accommodating groove formed in the cooling main body to accommodate oil; a cover unit coupled to the cooling main body to cover the accommodating groove; a supply port configured to supply the oil to the accommodating groove; a discharge port configured to discharge the oil from the accommodating groove; a separating unit coupled to the cooling main body and configured to separate a flow path formed in the accommodating groove into a supply flow path connected to the supply port and a discharge flow path connected to the discharge port; and a hurdle unit coupled to each of an outer wall of the cooling main body and the separating unit, wherein the hurdle units may be formed to protrude from a bottom surface of the cooling main body so that an area of a flow region through which the oil passes is decreased.
