I don't know if the BX25 seat is like the BX23 seat but when I first got our BX23 it had 285 hours on it. I experienced the same 'seat fight' that you talk about. I decided one day it wasn't worth the fight and I was going to win the battle once and for all. I lubed the daylights out of all the adjoining surfaces that rubbed against another surface underneath the seat and then spent a few minutes practicing until it became second nature to swing the seat around. I was so proud of myself until a couple of months later it started giving me problems again. I found that the flat bar that you lift up on to release the catches had gotten bent up in the middle enough so the catches weren't connecting to the round bar properly causing me more aggravation. I straightened the flat bar and everything works good as long as I keep the mechanism well lubed.
A little off the subject but connected. On full sized backhoes it is common practice when digging ditches to move the machine forward you just raise the loader and stabilizers and push the machine forward with the bucket, restabilize the machine and resume digging. I read someplace in the manual that we shouldn't do this with the BX23. I do it all the time and I can't see how it hurts anything if I do it properly so I just ignore that bit of advice in the manual.
