There is a TYM dealer in my area who has recently begun promoting the Branson 2515H heavily. I don't think he was selling Branson before the merger, but he's really promoting 2515s now. I don't have any inside information whether TYM is trying to clear our Branson models or if they really intend to keep selling this particular model. But it looks like the TYM dealer has jumped in with both feet to sell them.
As for the 2515H, my impression is that it has really good loader capacity and hydraulics, but it's still a 25hp tractor when it comes to operating a rotary cutter. If the OP primarily needs loader capacity and not HP for mowing, then certainly the OP should consider that model.
