I think that mid mount mowers are typically a little harder to mount and dismount and usually cost more than a comparable rear mount mower. The mid mount mower might give you a little better control of your cutting, but that would probably come with experience of using either one. I don't know exactly how all of the MMM are driven, either my a specific Mid-PTO, driven off of the front PTO or the rear PTO. I know that a small municipality around here (several years ago when I worked at the grocery store of the small municipality) purchased a compact JD and MMM. I watched the operator fight the MMM all summer trying to keep it going. It was driven off of the rear PTO through a Rube Goldberg series of belts and pulleys, and was raised up and down using the 3 pt linkage - all in all a really bad idea. The next year they bought a RFM and many of their problems disappeared. Of course, they may have not bought the correct tractor/MMM combo, and caused a lot of their own problems. Good luck.
