It's a 3PH mount BH. The B2410 has to be equipped with a special heavy duty top link brack for the 3PH. It replaces the two brackets that make up the anchor point for the top link of the 3PH on the tractor. The new bracket actually wrapped aroun the top of the trans case so it's better attached to take the increased load of the BH.
There also MIGHT be a set of braces that need to be installed on teh underside of the tractor to reinforce it. The older 2400 required the braces, and they come as standard equipment on the 2710 and 2910, but I don't know about the 2410 for sure.
Once the reinforments are installed (they stay installed permanently), teh BH hooks up like most other 3PH attachments with a few minor exceptions. One is that the BH has a permanently attached top link that's in a fix position. This causes the BH to be at a fixed height once the 3 link points are attached. You can't raise or lower it like most 3PH attachments. It's a safety thing to be sure digging doesn't cause the BH to raise up and wedge you against the tractor in awful ways.
The other thing that's different from "normal" 3PH attachments is that there is a hydraulic pump that goes on the PTO to drive the BH. It has its own self-contained haydraulics.
