My $.02, but I wouldn't want either of those models. The 2305 is too small for your needs and the 3032e just isn't as good of a value, $ for $ I think the Kubota L3800 is more bang for the buck, and I'm known as a Deere guy (take a look at my signature).
If you want a Deere compact for that amount of land, I would either recommend a 2520 or a 2720 and a zero turn, or a 3x20, preferably with a cab.
Even for part time use the base model 3032 and the luxury model 3x20 makes a huge difference. From the removable loader to better ergonomics, I think it's a very worth upgrade. If you are doing as much work as you state, although it's not full time, it will be quite a few hours on the seat.
I would recommend checking out other brands, take a look around, and if your like me, and stuck on JD, then at least you can get some prices for negotiating:thumbsup:
Good luck!
