I bought an older (2006 I think) X540 with the MC519 pull behind hopper. I am interested in trying to change it to the bagger system. I found some used ones that may work but the ad shows it will fit gt and lx models. Here is a picture of the setup. Anyone know if this looks like it would work on a x540? He said this power head is for 48" but they have another that will work on a 54" like mine. Since I already have the power head I am not as concerned with that if the the bagger system will work.
