The B2320 Kubota is a fine tractor. But before making recommendations, why don't you tell us more about your farm, where you are located, the things you plant and things such as this. It would be most helpful.
Like BPfick said, B2320 Kubota is a great tractor,others may chime in here but if you are hooking up PTO driven attachments (like brush hog/tiller/snowblower ect) you may need more Horsepower than 23......
Here's pics of mine, I only use Front End Loader, Backhoe and Box Blade , plenty of power for me ....
