I know the 1023 has the autoconnect deck so it may be different from the earlier models, but my 2320/62D combination attaches with two lift arms. It's meant to be adjusted such that the gauge wheels are just off the ground when on level surfaces. Does that seem to describe yours?
If so, the mower height range is controlled by the lift arm adjustments which should be set such that the deck almost touches the frame when fully raised. A number of us found that the dealers did not set them high enough and we couldn't get a decent cut height. After adjusting the arms all is good.
Mine is early enough it does not have the reverse switch. If it had one it would be gone by now. Relative to the seat switch, I had trouble initially because, as an old timer, I was used to standing up on the tractor while operating it. I have since retrained myself and don't have a problem. However, since you are probably smaller and lighter than me you may want to look at adjustments to the switch.
