Thanks to everyone who has commented. I don't see anything in my manual about towing weight but at 1.5 to 2 times vehicle weight the BX should handle 3000+ lbs or a 1 1/2 yds of gravel.
Particularly appreciate the advice on stopping.
I am thinking about building a small walking beam dump trailer to tow behind my BX25. Would appreciate any ideas as to workable size and weight. Also wondering if any members are running trailer dump hydraulics off the BX25?
