The operator adjusts the height of the deck relative to a ground surface by pulling upwardly with the fingers of one hand on the actuating member, while resting the palm of the same hand on the palm rest. This causes the engaging plate, and thus the pawl thereon, to be drawn out of engagement with the teeth of the index pla…
