Any tandem axle trailer would be fine. They only weigh 2,600#. I would not recommend a single axle but it could be done with a 3,500# axle if the trailer itself weighs 600# or so. This would leave enough weight room for the machine, chains, ect without overloading.
Its about 8' long so I would want a 12' or longer trailer so that I could get a good angle on the chains to all 4 corners and allow you to move the load to balance on the trailer.
