Update, the 3520 is finally back after a few weeks in the shop on the warranty repair (3PT Hydraulic valve failed) and it has a little brother (2004 GX255), and a MMM, so now I have a tandem for grass cutting. I will get back at using the flail mower too - it will be relegated to brush cutting at this point. All units fit in my detached garage so everything is fine! Since I gonna use both to cut, having to move them both each time is not an issue. As mentioned in another thread, my next activity is Operation "will those turf specials fit". One thing right away with the addition of the MMM, is that the unit feels a bit more stable just one flat ground. I have yet to try it on the slopes. but with the lil' GX255, I probably no longer have a slope issue, as it can handle all of those and in good time with its 54" MMM deck. So now the Turf specials are more for grass protection and comfort, than the stability worry fix. I gotta try running without my bucket on, and then without the loader on - but that will require some repositioning in the Detached Garage/shed.
