When I was looking for a brush hog, I rented a JD 855 of similar hp as the 2025R, and tried out a demo JD 513 (5ft) brush hog. With the HST tranny, there was no problem handling this size deck. Still have that JD 513 but running behind my JD 4300 at 32 hp. Only problem that I can see, would be trying to run it without the FEL to counter the weight on the 3ph.
