Yeah know what you mean about mastering the controls - my first dig kind of like trying to pat my head and rub my stomach!! But my issue now is if trying to use 2 levers at once with one at reasonable speed, it barely moves on the second axis - wondering if thats normal when moving in the air (ie without resistance) or i have an issue with hydraulic flow...
My first few tries with the bh were like that too. After a while I started to notice if I very gently worked the controls, I could get them into a combination movement. The more I tried it, the better I got. Also, I learned to lower the tractor rpm and not run it at full pto speed. Everything got smoother and more controllable. My bh is on the larger tractor, so it's different from a BX, but the same idea applies. At first, you only need enough rpm to get sufficient hydraulic pressure and flow to run the hoe. It'll move more slowly that way, which is a good thing while you're getting the feel of it. When you''re good enough with the controls, you can increase the rpm and make faster movements.
