Not sure that's true. The Deere is heavier, the specs are nearly the same. They are very comparable tractors. The HST+ on the Kubota is pretty neat feature. I've never gotten the chance to fully try it out, but it does seem useful, and wouldn't be afraid of it.
With opening up the brands, I would second Ken's opinion to look at all your options, but you aren't going to get 95% anywhere besides Deere.
Martian--the specs I've found show the Kubota 3240 weighing in at 3395 lbs while the JD 3320 tips the scales 2900, both without loaders. Either option would certainly be an improvement on the 2087 lbs of the 3032e. I'm sure I would be happy with either the 3240 or the 3320, so the issue comes down to out-the-door price and my comfort/satisfaction with the dealer.
As for looking at other makes, the only other options that are close by are Mahindra and LS. Both dealers have received mixed reviews from customers, so they are not on the radar screen.
Thanks for your response.
