So I dug 50' of 4' deep utility trench and the BH never faltered. I guess we're back in business. My opinion of my BH90 is that it is between repairs at the moment.
If I ever buy another hydraulic attachment I will be sure to slide the unloaded cylinders on the pins to see if they are properly aligned or side loaded. I recommend others do the same and walk away if the cylinders don't float.
Thanks for looking,
