I've had my L2501 since about December. Front end loader, industrial tires, quick attach/ skid loader attachment on the bucket and rear liquid filled tires. Couldn't be happier although I just have a finishing mower and rear blade.
You should be able to handle the rotary cutter just fine, but you'll be pushing it to the max. I've seen some people run the 60" on the L3901 if that gives you any ideas. Keep it in low gear and just go slow.
I looked at the JD 3025E and it didn't interest me at all. Aluminum rear end (can't get a backhoe for it), 2 speed transmission, fuel tank behind the seat with a cheap fuel gauge on the filler cap, and the front end loader didn't come off; just the bucket. All that for 2k more.
Didn't test drive any other brands because my mind was set, but I wish I did just because I like tractors. Mahindras appear cheap to me and I've heard around here they are priced similar to Kubota. Since this is BITOG, I've also seen that their oil filters are unique and around $40 each. No thanks.
We don't have any other dealers locally aside from a small Kioti dealer 1 hour north that's not been around very long.
