My TZ22 is also having the cracking issue on the blue fiberglass fender shield that the seat assembly fastens upon. I am not alone in this issue as I have seen from previous postings. While I am willing to tackle this issue myself, I am wondering if anyone has the steps involved in removing said panel from tractor to access the underside of where the seat brackets fastens. I am going to fabricate a square panel to go under the seat panel and on top of the panel and then fasten the seat bracket to that fabrication. I also plan to add some fiberglass underneath as well to stop the cracks and just reinforce the whole thing. I do have a couple of PM's out there, but so far no answer from those who seemingly have had to remove the blue fender shield (or whatever it is called). If anyone has a better idea on how to resolve this issue, let me know that as well. I did contact NH and got the standard answer to contact the dealer. I have emailed the dealer rep I dealt with when purchasing the tractor, but have not heard back. He may be on vacation because he is usually very good at returning emails and phone calls.
