How often do people typically take their tractors to the dealer? My tractor just doesn't go to the dealer... ever.
Looking at the Kioti, I think it may be OK in length for the U-Haul car trailer, but slightly too narrow for the two tread design.
Our local equipment rental does also rent utility trailers that would probably work. And renting a trailer once every couple of years might be cheaper than licensing a trailer.
As
@Robin Veerman mentioned, towing a trailer does take a little practice. Backing up? Parking? Not running over stuff, etc. Nothing insurmountable, but not necessarily comfortable for once every few years use.
I took my nephew to practice at a shopping center parking lot. I told him to back the trailer around a corner and next to an island. We ended up about 30 feet away, and he asked me how close does it have to be in the real world??? An awful lot closer than that. Each situation is different, but parking a trailer may need to be within a couple of inches. And, yes, corners are part of life.
Now, that said, a good utility trailer can be very handy for hauling a lot of stuff, not just a tractor. Trips to the local building supply? Hauling Hay? Buying more tractor implements? Hauling cars? Bringing home that next project? Hauling garbage to the dump?
The larger dump trailers may even fit your tractor, and can be very popular.
Pick out a trailer that will be flexible for the type of projects you are interested in.
