The JD 2320 is a larger, and more capable tractor with nice features like position control, steering brakes, etc., and they have the drive over mowing deck........... but if you really need a 2305 sized tractor then the Kubota
BX24 is probably the better deal here. Believe me, there is a difference in how much impact the larger tractor will have on your yard if that is mostly where you will be using it. I had both my Kubota
B2620, and Simplicity Legacy (1000-1200 lb.) tractors out yesterday doing yard clean up. The Kubota left marks, and shallow ruts in several places that the Simplicity just floated over. Regardless of what many others will say here, I think that the BX / 2305 / MF 2400, etc. are about the maximum size for all around yard work. There are some areas on my yard that I have to mow the same way every time, and after ten years, I can even see compaction from my Simplicity. For work off the yard, extensive loader work, etc. a larger tractor, starting with the JD2320 in size will work out much better in the long run. Though I love larger tractors, I have to admit that the best solution is a tractor for tractor work, and a good mower for the yard work........ up to BX size. If I had to choose just one right now (and I would hate to since I often use both at the same time like yesterday when I was chipping fallen branches into a trailer behind the Simplicity) I would have to choose the 2305 / BX / JD X700 series (if no loader work)) I have both a 3+ acre yard, and woods, rough ground so I like having both. Starting with a clean slate I might buy a larger tractor (
B2630 size) and a different mower ( I have a love / hate relationship with the Simplicity mower deck)
