Hi Garrabo,
I have not had good luck in the past pulling a plow. Though I have not tried it with a BX, I used to have about a 20HP JD with a one bottom plow. In sandy loam soil, I was never able to get the plow to do a smooth job. I have pulled 3-7 bottom plows behind ag tractors so I know what they can do if set right.
On mine, I was never able to hold the plow (tractor didn't have good 3 pt sway bars) in position and I couldn't maintain ground speed due to wheel slippage. If you can't keep the ground speed up, the dirt won't turn over.
If you have access to the unit, give it a try. If you have to purchase it, I'd sure want a money back deal so I wasn't stuck with something I'd not be satisfied with.
Just my two cents,
Ron
