I'll disagree on the radio..... I use mine all the time. Nuttin better than blowing snow or mowing listening to good music to pass the time. I also use the radio with the windows open while planting flowers or whatever, don't always need to be in the tractor to enjoy a little music. In my tractor vids on youtube, it is the radio playing in the cab, not music I've dubbed in. I will say that i'd opt out of the Kubota (Panasonic) factory radio though. Get the Kubota box and put any single din car radio in it. You can buy three times the radio elsewhere for what Kubota wants for their Panasonic radio.
One thing that's nice on the Kubota O.E. radio is you can get the National Weather Service on it. I don't know how many aftermarket radios have that.
