A transmission for a skid-steering vehicle having two tracks or two sets of wheels in which power is transferred from one or more prime movers to the tracks or wheels through a gearbox is proportional to the sum of the input speeds and the difference between the output speeds is proportional to the difference between the input speeds, the internal gearing of the gearbox consisting of two only differential gearing sets each comprising three elements within connections between two of the elements of one of the differential set with two of the elements of the other differential set. A fully hydraulic drive is preferably provided between the prime mover and hydraulic motors driving the gearbox.
