A hydraulic travel drive includes a primary hydraulic machine and at least one secondary hydraulic machine connected in a closed hydraulic circuit via a first and a second working line. A first accumulator is connected via a first valve to the first working line and via a second valve to the second working line. A second accumulator is connected via a third valve to the first working line and via a fourth valve to the second working line. The four valves are non-proportional switching valves each having two defined switching positions. A method for operating the drive includes comparing the high pressure working line to the first accumulator. If pressure in the accumulator is lower than in the working line, the first accumulator is connected to the high pressure working line for charging until pressure in the accumulator corresponds to that of the working line.
