First time home owner here so I apologize in advance for the lack of part name knowledge. I just got a john deere srx75 and after a couple of mows the steering went out. i'm not familiar with what parts are what but I can see this part of the steering wont stay secured so im not quite sure if the shaft part needs to be replaced or other thing it attaches too. any advice would be appreciated!
