I have a 345 John Deere seat that is coming apart and was wondering what to do to fix it . The seat is still in good condition not cracked or anything .It is coming apart from the yellow plastic to the black base it has some type of glue it lookes like that holds it into the base . The glue is dried out and is letting the seat pull away from the base.About 90% has pulled loose . I hate to spend a $100.00 for a replacement seat when this one is still in very usable shape. I was going to buy some Gorilla Glue and try it but it is not recomended for plastic. Also thanks for all the responces I have received on the 345 dust issue . This is a great sight. Thanks Again
