Hello guys,
I'm pretty late to the party but thanks for all your help with this! This is my first post so hopefully I get it right. I have a Bx2370 with a Bx2750d blower and I hated the cheap ring bracket it came with so I upgraded to the 77700-05888 bracket. Everything we searched through the dealers did not indicate it was the correct bracket for my tractor however it does bolt right on and it looks great. 1 of the bolt holes in the floor pan was covered with an orange sticker. I made a small modification to the bracket because it originally left the rotating handle sitting a little to close to the bucket control lever for my liking. I drilled another bolt hole to move it over which made everything fit just the way I want. As far as I can tell from my measurements, it won't interfere with the FEL. Bolting it up was a pain because the outside bolt is inside of the cast aluminum support located underneath the floor pan. I've read you can use a longer carriage Bolt if you can't get it tight. Here's some photos for anyone who is interested in this upgrade. The pictures show the bracket mounted in the factory holes and then again after it had been moved over.
