Attachments 1998 Cub Cadet TM6E wheeled trimmer conversion

I am looking for a how-to or information on converting my TM6E (1998) to use a brush blade such as a Forrester blade. Can anyone point me in the correct direction. I believe this is also known as an MTD 25A-110-100 (among many other models and brands). This has been a great tool and other than pull ropes and tune ups has never needed repair. This year I need to find new fuel line for it (yep...only took it 18 years to rot...just not making em like they usedta). Matter of fact I cant find the B&S engine manual that came with it and all the labels have faded or dropped off. Any info is appreciated!
