A height of cut control system on a mower deck includes a linear actuator connected to the lift linkage. A height of cut dial has a plurality of operator-selected desired cutting heights, and a deck height control is connected to the electronic controller that commands the linear actuator to lower or raise the mower deck to the desired cutting height when the deck height control is in a down position or an up position. A deck height display provides visual feedback of operator selected cutting height and actual cutting height. If the actual height is at least a specified amount off the operator selected cutting height, the electronic controller may automatically adjust the mower deck by commanding the linear actuator to move the mower deck to the desired cutting height.
