I think for the uses you described, the
L3200/
L3800 would be perfect but as others said, the problem with the jerky thee point hitch would probably frustrate you to no end with your intended uses. That being the case, I'd go with the
L3240 or
L4400. Both should be more than capable of doing the jobs you outlined. The
L3240 has probably just the right amount of hp for what you want in a slightly bigger frame and is much heavier than the
L3800. It also has lots of nice features (HST+ transmission, great 3ph, tilt steering wheel, flat operators platform, cruise control, integrated FEL controls). The GL40s are definitely the "Cadillacs" of Kubota's lineup. Here's a good overview of them:

The
L4400 has a slightly bigger frame than the
L3240, 10 more hp, and weighs about the same without all the bells and whistles.
If you're a numbers kind of guy like I am, check out the specifications for the tractors on kubota's website:

The bolt on cutting edge is great but probably something that most people could do without if you want to save some money. The guy I buy soil and bark dust from has one on his
L4240 because he is scraping material off asphalt all day. That's the kind of use I think of where you would really need one. I would probably say the same thing about the HD bucket. Of course it just depends on your intended uses.
I second the grading scraper idea. Both Landpride and Woods make nice ones. I love mine. Worth every penny. I still would like to have a nice rear blade for ditches and scraping gravel back onto the road though.
Also, don't forget ballast in the tires. Rimguard is good stuff. It's made from beet juice so it's non-corrosive and safe for the environment (i.e. it won't kill grass) if you do happen to get a leak.
