I looked at some pictures on the deere site at the 6115m vs a 5115m... From the looks, the interior cab design took a major step backwards for the 6... The 5 looks really nice.
I'm honestly torn between a 5115m and a 6115r... I'm afraid if I get the 6r it will be too big for what I will use it for though... But it's killer nice inside and out. But again, it fits the needs better for the long term possibilities of bailing hay and row cropping, if I decide to.
The place we are mowing now has some clearance issues... Using the 3520 cab and it barley fits in some areas...
