A hydraulic vehicle drive, particularly for mobile hoisting platforms, has a first pair of wheels drivable by means of first wheel motors (8, 9) in dependence of a first control valve (2) and a second pair of wheels provided with second hydraulic motors (15, 16). A switching arrangement (19) short-circuits the second hydraulic motors (15, 16) in the driving-free state and for cooling supplies them with a flushing flow. In the driven state a second control valve (5), in dependence of which the second hydraulic motors (15, 16) are drivable, is activated, and if required connected with the first control valve (2). Thus, optionally, the first wheel pair can be driven alone or together with a certain driving output from the second wheel pair.
