Unless I’m mistaken, you can use that blower and front hitch all the up to the current BX models.
However with the 80 series, they did change the way the hood opens and it will interfere with the front hitch. The hood will only open about half way. The other things that will change is the hydro couplers are now flat face, so those will need swapped.
That being said, with the 80 series they came out with the new 4 point front hitch and a new style of blowers for it.
One last thing, you may have to change the shaft in the hitch depending on the model it’s going on. I think there are only two different lengths of that shaft. Check with a dealer as I’m not positive in that.
