A gearbox 20 for a skid-steered vehicle has a housing with first and second opposed sides, a steering input shaft 16, a propulsion input shaft 13a, 13b, a controlled differential 40 and a gear reduction unit 30a, 30b and/or gear change unit 31a, 31b. Steering and propulsion input shafts 16, 13a, 13b are on the same side of the housing. Controlled differential 40 is between and connects two drive shafts 14 and is drivable by steering input shaft 16, and outputs 48a, 48b from differential 40 connect directly and solidly via drive shafts 14 to the gearbox outputs. Propulsion input shaft 13a, 13b, and gear reduction unit 30a, 30b and/or gear change unit 31a, 31b, are connected in parallel with an output 48a, 48b of the differential. Also claimed are a gearing configuration, a gear change unit with a slidable dog hub and corresponding gearbox, an alternative gear change unit, a drive unit and a drive configuration.
