I have a 5' x 10', 3,500#, single-axle, no-brake trailer that is entirely NOT up to the duties of trailering my machine, even without the BH attached. Not only do the single tires roll under weight and the COG is all off, the difficulty of balancing tongue weight (with lack of space for proper tractor placement) and the uncertainty of no braking is very unnerving. It is also difficult to properly tie the machine down.
I am a couple of weeks from purchasing a 7' x 16' 7,000# dual axle car carrier. I can get one with slide-out ramps for $1,895 or one with fold-up ramps for $2,095. I'm liking the one with folding ramps since the ramps themselves have "stands" so I can drive my machine on the trailer without it necesarilly being connected to a vehicle. It also limits the upward force on the ball (and that uneasy feeling of something breaking) when loading the tractor.
Plus the car trailer has the added bonus of being able to carry a car. Never know when that may come in handy.
My Dad is retiring at the end of March and I'm helping him with some stuff around the house (adding culvert for the 5th Wheel, rebuilding driveway, installing privacy fence, etc.). I also have some things to do at my Mom's house (pulling up a stump from an old Pear tree). They both live 200 miles away. Being able to safely transport my machine will be a real help.
