A couple of notes for information:
1- The 2720 and the 3320 have the same engine
2- The 3320 has the reputation of having a high center of gravity for things like hillsides. You would want to set the tires to the wide position for best stability and probably fill the tires. Consider a rear mower/rotary mower instead of a MMM and back down the slopes that need to be mowed.
3- The hydraulics on the 2720 are faster than the 2305, but the lifting capacity isn't tremendously higher.
4- If you have a variety of attachments for the 2305, stepping up to the 3000 series will mean replacing some of those attachments whereas the 2720 will be largely a lateral move in that regard.
Personally, I wouldn't even think of moving these trailers with any of these tractors, mainly to the lack of braking ability. The ratio of the weight of the tractor to the weight of the trailer is far too low. This seems more like a job for an all terrain forklift.
