Pj sent me the instruction for this a year ago. I was going to do it, but never got around to it. I want to do it before it starts raining and the grass really takes off here this year (if that ever happens.) My question is this. I see in the instructions it says you may need to weld the top plate. I am not sure I follow this. Is this something that usually needs to be done? Or not usually? I don't have a welder. I have about everything else, but the shop I rent does not allow it, so it will be a bit of a problem. I'd like to see some pics of what actually needs to be done here.
