I have a 2014 BX, and always enjoy seeing ( and purchasing) new implements and checking out the upgrades. It does appear that Kubota listens to the end user. I like the new loader levers, my older model has two manual hitch pins, which is really simple. I added the 3rd function setup, for the grapple, and again It has manual disconnect hoses, which only takes a couple seconds to remove.
The new designs look very nice, especially the tilt up hood! I currently need to remove the 4 bolts that hold the grill guard on, to get full access to the engine compartment. To me, that is the biggest improvement to the series. I'm not sure how the new stick location will be, I'll have to play with one to see. Just my .02cents worth of info and opinions
