A foot pedal mechanical linkage system is provided in a hydraulic stretcher used for transporting patients. Two hydraulic jacks are mounted on the stretcher's carriage at opposite ends of the stretcher, and they vertically adjust the stretcher's litter on which a patient rests. A first foot pedal assembly at one end of the stretcher and a second foot pedal assembly at the other end activate the hydraulic jacks. A linkage assembly connects the first and second foot pedal assemblies. An operator of the stretcher can raise or lower either end of the stretcher separately or together from either end of the stretcher using the foot pedal and linkage assemblies.
