Nuru,
I tend to agree with John. Well excepting for one small detail. The topography of your property. If you have open spaces and not many trees and other obstacles to mow around, a 3pt finish mower is the way to go. If you have a lot of trees or other things that make cutting a pain, you may have to consider the MMM. Consider this, the rear finish mower is going to hang off of the back of your tractor 5 to 6 feet. When you make a sharp turn, it swings wide and so you may have go back a recut some areas or you may have to pay attention and not bang into things.
Or you can take the minimalist approach, use the 4100 to take out all of the obstacles and have nice straight mowing areas. /w3tcompact/icons/wink.gif/w3tcompact/icons/smile.gif
