Hi:
To the previous point about a RFM. I have a 72" 7 Iron MMM on my 3720 and switched to an 84" RFM (I still have the MMM and use it for Material collection/leaves). I run loaded R3's. My initial reason was to not have to deal with the pain of removing/installing the MMM every time I wanted to take it off to do some serious loader work. (It's a pain in the A#$ on the 3720 compared to the 62C on the 2305). You can do it, but it's a lot more work than on the smaller tractors.
After using the 84" RFM I can tell you 1 thing that's great about the RFM.... NO TIRE TRACKS!!!! I'm running 6" extensions (each side) on my 3720 with WIDE turfs and with the MMM when I mow I leave behind flattened grass (not dug up, just flattened). With the RFM it 'sucks up' the grass when it cuts it and I never drive over it again so it looks very nice. With the MMM, even though the Deck covers the tires width, Once the rear tires hit the grass again you'll flatten it out.
I have a Rear discharge and my only complaint is that I'd like a mulch kit since I can't direct the discharge like the side discharge MMM.
