Model MAX25 and eMAX25

I am looking at several of these models and I have a questions. If I get one without the backhoe (I have seen some with the TLB versions of the Max 25) can I easily add a backhoe later or do I need to do a lot of work additions...like plumbing for hydros and do I need to add a subframe at an additional cost? Do these models already come with what is needed to simply add a backhoe to them. Most small tractors have no subframe for a backhoe unless the package is ordered together. Thanks
