I run a Mahindra 48" rotary brush cutter behind a 2011 BX 25.
It is actually made by Kodiak Implements, and it's very heavy & quite durable.
Yes, my BX 25 has more rated PTO horsepower than a BX 1880.
Using the current Kubota website PTO horsepower numbers for a BX 23s and a BX 1880,
it's 17.7 PTO hp, and 13.7 PTO hp.
I haven't had any problems so far, other than several broken PTO driveshaft shear bolts.
I will say that the last time I checked the Land Pride implement website, the Factory matched rotary
brush cutter for a BX of any type was their 42" model.
That being said, my 48" brush cutter has done a really nice job for me on my food plot fields.
Walk your ground that you are planning to brush cut several times before actually doing the job.
When you make your first pass in uncut material, listen to the engine/watch your tachometer and use
a slow enough travel speed to keep the 540 PTO where it needs to be.
Then as you start overlapping into your initial cut, adjust the overlap width as needed to keep the
540 PTO speed where it needs to be.
I leave the front end loader & bucket on my BX 25 when doing brush hogging, as the front weight
does a good job counterbalancing the rear brush cutter weight.

One other problem I had was the first year I did food plot brush cutting, and I had never brush cut that food plot field before, even after extensive walking before doing the brush cutting, I found wet/soft ground and buried the rig in the mud and needed my local farmer friend to pull my BX 25 out of the mud with his large farm tractor. The only thing damaged was my pride.
