After months of thought, I finally decided on which JD model I feel will best serve my needs. I was ready to finalize everything (i.e. order the beast!) until I run into a snag. I had decided on either a 3120 or 3320 (HST of course) w/72" "7-Iron" MMM, snow blower and brush hog. I also wanted the R3 Turf tires since this beast will see 99% of it use mowing my yard and 9 acres of open field. The dealer informed me that he didn't think the MMM was available or would work with the R3 Turfs. Can anyone confirm or deny this? He was checking into it and going to let me know but I haven't heard anything back yet. I can't imagine that this could be the case as I don't feel it makes sense considering most order the R3's for mowing and most would mow with the MMM. Anyone have any insight on this issue? Thanks!
