Meridian Equipment has a 4690 and a Woods on their lot right now. I've been tempted to head south for a border raid but the difference in the dollars adds 25% right now, plus I get dinged 13% in taxes to import...
I posted an ad for a Kubota BH75 this past week. Based on reviewing other B2710s, it appears that it is compatible with the B2710 given the proper subframe. The subrrame included with my backhoe is part number BH4975.
