I have a '98 JD 345. The hood had cracks about 16" on both sides. Two weeks ago I decided to do something before the cracks went to the top and I would lose half of my hood. I used two tubes of "J B Weld". Sanded the area very well, and applied a large amount of the stuff on and along the length of the cracks . It seems to be holding.
I have used the tractor a total of ten hours thus far, and everything seems to be holding...!!!
