The extent of my experience operating a BX is limited to driving one around a dealer lot for approximately 3 minutes. I have, however, used turnbuckle/chain stabilizers, fixed length flat iron stabilizers, variable length rod stabilizers, and telescopic stabilizers (obviously on a variety of tractors). Currently have telescopic on my L.
If you want ZERO play in the 3 point, OEM won’t do that, at least not the ones on my L. There’s a slotted section that intentionally gives a pretty fair amount of play. The holes other than the slot don’t give much, but still a little, as in probably the 3/4” total play but I’ve never measured. IMO a 3 point hitch isn’t designed for zero side to side play. For example, I’ve had fewer repairs to my bush hog since changing to the slots in the stabilizers instead of the holes. The slots let it move a little when it inevitably hits stuff, and I prefer that few inches of movement to the alternative of something bending.
I’ve seen a few folks crank down on their turnbuckle/chain stabilizers to keep everything “perfect”. I think that’s not useful and setting up to bust something, but if that’s what you want, it ain’t happening with OEM telescopic stabilizers.
Personally, I think the telescopic is a significantly easier and faster to use than the other types I’ve dealt with and it’s at least as effective. Obviously, that’s an opinion, not a fact.
BTW, I don’t have a backhoe, don’t have a quick hitch, and switch 3 point implements routinely. I’m aware quick hitches are extremely popular. Maybe I’ll get one someday, but not today. YMMV.
