Brian, make sure the tailer is long enough and heavy enough to carry MORE than what you are going to carry. I have often put an implement on the front of my trailer, put another implement on the 3pt hitch, and then driven the tractor up onto the trailer and rested the bucket over the top of the implement on the front end. Also keep in mind added ballast, fuel, etc. If you have fluid filled rear tires, those could add a whole bunch more weight to that tractor. Also, many loader weights do not include the weight of the bucket itself, check your specs, I don't know if Kioti includes the bucket weight in the weight of the loader, but the reason many do not is because there are often several bucket size/type options available. You may find out that the loader is 700# and the bucket is another 200# to 400#. You may find you are over 5000# with the tractor, loader and implements. Also remember the GVW rating includes the weight of the empty trailer. I would say you really need a 7000# equipment trailer with solid ramps.
BTW, when I had my trailer built for me, I specifically ordered a REMOVABLE 6' ramps. Instead of tipping up for transport, they actually have to be removed and carried on the trailer. The beauty of that is that I can carry longer loads that hang slightly off the end of the trailer.
