Exactly! That was my pain point. I did not have a Massey Dealer within 100 miles of me when I bought, AND Massey Didn't have any GC1720s within 4 states of me at that time. I also committed to buying a GC1720 over the phone and after the dealer took all my personal information for Finance,they called me back 1/2hr later and told me they sold it to some guy that just walked in. I basically said Fine, I will buy the Kubota then since that was the last tractor in the area.
Sorry the BX wasn't up to your expectations, but from the specific complaints you listed, the GC1720 probably wouldn't have worked much better for you either. From a size, weight and power standpoint, there isn't much one will do that the other one can't. You'll no doubt be happier with another machine but will take a hit on selling/trading your BX25. Would suggest that some of the things you didn't like about the BX would only be resolved by going larger next time (bigger tires, more digging capacity, more clearance and traction, etc.). Good luck.
