Item did fit my bx23s, i was a littlt concerned it would not since when i got it the box said fits bx 25 d only, although i will say that my tractor is a 2022 model and i beleive the older bx 23s do not have the thumb mounts already welded on the bachoe arm,but mine did. I did have to drill out one hole on my backhoe to get the pin attaching bolt to fit and line up. It did not come with instructions , i figured it out pretty quick because i have a thumb on another piece of equipment, but for someone with no mecanical skills or referance it might be difficult. The product itself is sturdy and well built, i gave it a 4 rating only because of the reasons mentioned above.
