Abstract: A material-handling vehicle including a structure having, a ground engageable propulsion arrangement, a loader arm mounted for up and down swinging movement, an operator's cab, an engine having an output to provide power for the movement of the loader arm and propulsion of the vehicle and drive to connect the output to the ground engageable propulsion arrangement to propel the vehicle. The vehicle has a rear axle and the engine is mounted on the structure rearwardly of the rear axle. The output of the engine is kinematically connected over the rear axle to an input of a change speed gearbox an output of which is kinematically connected to the ground engageable propulsion arrangement. The output of the engine is kinematically connected to an input of a transfer mechanism which has an output, disposed higher than the input, which is kinematically connected to the input of the gearbox.
