I took the mid-mount mower off my 2305, attached a 1-bottom moldboard plow to the 3-point-hitch, and plowed my garden for the first time with this machine. I took the plow off and re-attached the mower with no problems. But now when I raise the lift, only the rear arms rise. The mower doesn't move. As far as I know, there is no selector lever for selecting between the mid-mount lift and the rear lift. I feel like I'm missing something simple. Any of you 2305 owners know what it is?
