Yep, I read up on all the
B3030 radio posts, including yours. The
B3000 may have a little more sound insulation than the
B3030 as Kubota claims, but I don't know for sure. There is quite a bit of foam deadening around & under the floorboard. I did a little digging around because I am considering adding some more and needed to see what was already there, but Kubota actually did more than I thought they would have. I still think I can improve on some of it with some better quality stereo sound isolation/deadeners, and some additional foam at some of the floor penetrations.
There is a decent amount of hydro whine that makes it's way into the cab. Pretty much the same as my open station
B3030, but the sound that makes it into the cab is definitely amplified by the cab.
I do think with a little more work in the sound isolation dept, and a decent set of speakers, I can create a decent sounding radio setup that I can live with. I've been using headphones & my iPhone, but I've decided that I would prefer an in-cab radio. There are a couple companies that specialize in tractor stereo systems, and since they're small companies and I can talk with the owner, I'm pretty confident we can come up with a system that will work pretty well. One thing I think will be critical is a set of self-contained speakers that I can mount close to my head, and utilize some rubber sound isolation to keep the tractor vibrations away from the speakers & housings.
Since I don't expect to need any bigger machine in the foreseeable future, I think I can customize this one to my liking, without worrying about losing my butt on the upgrades when I trade it in. Knowing I wanted a cab of some sort is what kept me from going too crazy with upgrades to my
B3030, but after nearly 5 years with this size machine, I'm still very happy with it, even moreso now that I have my cab, so I have the time & motivation to try to get this machine all set up exactly the way I want it. Plus, I don't want anything to do with any of that Tier 4 stuff on my tractor for a long, long time. Bad enough I have to deal with that power & mileage robbing garbage on my truck.
