Hey somebody has to take up Cowboydoc's and Rockyridge's slack.
The 3720 is a great tractor. I'm sure the Kubota is a good machine too.
Make sure you check out the dealer's really well for service, parts, etc.
JD has an online parts dept that you can look up parts, exploded views, prices, availability and even order if you want to. No one comes close to that.
