Interesting that they still leave the sheet metal seat pan exposed. My tractor is a bit more air tight at this point, aside from a couple of little areas that I still need to address. Aside from you having time to crawl around in and under that machine and snap some photos, I'd be interested to see what they did to make it airtight. There are a lot of air spaces where the floor pan hits the fenders, and of course, every pedal or lever that penetrates, has quite a bit of space and not all of those areas were addressed very well. I've further addressed some of the areas, but the rear diff locker is going to need even more than I've already done.
I was hoping to have a nice weekend sometime soon, so I could go back and add foam pieces to finish sealing things up, but we keep getting spells of cold & snow. I have some work to do on cars this weekend, and looks like after today, the snow returns through Thursday, so the tractor may have to wait another week.
I know folks will complain about plastic fenders, but that's one more area that could potentially cut down on sound transmission, but if it's just a bolt-on piece from the cab frame out, then that won't do much, other than allow an inexpensive way to replace a damaged fender. I wonder if now they'll just offer a wider replacement orange fender as their fender extension option.
