Thank you. I did see that Kubota only has the BH as an option on the bx23s and not the other models. The MF dealer said it was possible to add a BH later, but they wouldn't advise it as it would require substantial work and cost significantly more than getting one initially. JD said you could add one later, but to not wait too long as they will sell a "kit" of everything you need for a few years before they stop selling the "kit" and you would have to purchase everything individually which would be substantially more $.You are very much on the right track with the GC and 1025R. I would recommend a trip to the Kubota dealer to check out a BX (2380 or 2680) as well.
But do not under-value the convenience of having good dealership support nearby. The best tractor in the world will need dealer support and/or parts from time to time. If it is a logistical ordeal to trailer the machine back to the dealer, or even to drive there for parts, that is a big ownership downer.
This may be a non-issue for you since you are not planning to buy a BH. But of note on the BX machines, you cannot add an oem BH to a 2380 or 2680 later if you change your mind. You need to go all in on the 23S to get a BH upfront, or accept that you will have to trade later if your needs change and you want the oem BH. I do not know whether the same is true with the MF GC series. But JD will sell a BH for the 1025r to you later if you want to add one. (At least they used to. Worth double checking!)
The comment about the trailer is valid. I presently do not have a trailer I could move the tractor with. I've been planning to get a new utility trailer for a bit, but have managed with my little 4x6' HF trailer so far. The MF dealer is about half hour away, while the JD dealer is about 15 minutes away. It's about 12 miles so while it would take forever I could drive the tractor to the JD dealer if necessary.
I've had a bit of hit/miss with the JD dealer. I went there first when I bought my property to buy a lawn tractor and when I engaged the blades the entire tractor shook and the salesman told me it was "normal" so I went down the street and bought my Cub. The Cub dealer turned out to not be great and they now no longer sell Cub and do sell LS, but I refuse to give them any more of my $. I did recently buy a new chainsaw from the JD dealer as they were able to get the saw I wanted (MS 400c) while others couldn't, but it took them making several requests to get it from another location. The parts department seems to be way better than sales. I did like the MF dealer a bit better, but either would probably be alright.
