I have a Befco 11-150-231,,, about 53" wide, does what it's supposed to, I got it used and had to replace the teeth, they were completely worn. I got it for $500 plus the new blades were $240 so $750 ish total. I had a down payment on a 60" tractor supply tiller, it seamed like it was fairly heavy unit for the price
The Befco seals do seap, but not enough for me to pull it apart at this point , I use it a few days a year,,,,the smartest people I know are involved in a 3 pt implement cooperative,,,,a bunch of people going in on a rarely used implement especially the expensive ones
Sorry but I run a
B2920, a lot bigger than a BX, I would check to see if you can run a 48",
Is yours 18hp engine , so you probably have 13 or 15 @ PTO, I did know where a 36" used one was for $800ish,,, pine plains tractor new Holland dealer518-398-7107,, pine plains NY
