An electric linear deck lift assembly for raising and lowering in a controlled and accurate manner the cutting deck of a lawnmower to a variety of different heights, including preset heights. An electric motor drives a linear drive rod connected to the cutting deck, thus raising and lowering the cutting deck to particular heights as determined by a positional sensor which monitors the position of the linear drive rod or an encoder which monitors the direction and number of rotations of the electric motor. Also disclosed is a combination of two or more deck lift assemblies for raising and lowering different sides of a cutting deck.
