I have a JD212 with at 47" deck and an electric lift. I read the manual and it says to move the electric lift lever to the full up position and then turn the Deck Depth Control knob counter clockwise as far as it will go. Then adjust the thumb know on the lift control to the height that is desired. Use the electric lift lever to lower the deck. It never states to do anything more with the Deck Depth Control. Am I to assume that with an electric lift that this control is not used when in a mower deck operation?
