No, but trailers are cheap, and you probably need one anyway if you have equipment or live on any sort of average.
The benefits of a small excavator rather than a backhoe outweigh the disadvantages. Removing a subframe and backhoe so one can use a box blade or pto driven equipment is a bigger job than putting a mini on the trailer.
You people must really not know how to hook up 3 point attachments and I also question the mounting and dismounting of the backhoe because all but the industrial TLB’s seem to be very easy. The backhoe on my Kioti is easy to connect and disconnect and takes me less than 3 min on or off! The hoe on my buddies JD is a bit of a pain but still takes only about 9 min including taking off the lower 3 point arms or putting them back on after removal.
When I look at putting the chains on anything for the trailer it’s actually more work just getting the chains and binders out of the box then it is hooking up the hoe!
