3x20 Series with MMM?

[Neophyte]

Does anyone out there have the 72" MMM on a 3x20 Series (3320) with the larger R4 Marathoners or have you seen this combination?

I have seen the MMM with the standard R4 tires and it seems pretty close. I'm just wondering if there would be any clearance problems with the larger R4 tires.

I asked my dealer but he could not give me a definitive answer.

I also posted this in the Owning/Operating forum but I did not get any responses.

I have seen your post in both spots but have no mmm check clearance on.I own a 3720 with the larger R4's and love them very easy on grass. Check the build your 3320 link on deere's website and the front R3 turf and front larger
R4 are both 27x8.50x15 so they sould be the same size. Buy the larger R4's.
