I think at this point that owning a trailer is out of the question. I am unwilling to devote the time and money to property taxes, insurance, and maintenance on one more set of wheels. If necessary, I guess I would rent a trailer when I need it, or would be willing to transport it without the front end loader. at the current moment, I have no need to transport it whatsoever. I do transport my John Deere 455 riding mower in this way and it works quite well. I just don't want to be in a position where someday I will need to take it to the dealer for repairs or do some box blading at a rental property and will not have the ability to move it. It did occur to me after posting that I do have a 5 x 8 high side equipment trailer with a 5000 pound axle on it. This might be able to move the tractor if I can put the front end loader down on the tongue.
I'm sure some of you can relate. I am coming out of a period of time where I just bought too much stuff. Anything that I only used a couple times a year I am selling and will be renting in the future. The stuff I do use I am repairing or replacing such that it is in very good condition.
I have a 1500# machine that fits in the bed of my pickup truck. I bought ramps from the factory, and I removed the tailgate from my bed. Then I pinned the ramps onto the bumper and I was able to back it right up into the bed of the truck with an implement on the FEL arms and off I went.
With that said, its a scary ride up steep ramps into the bed of a pickup. I imaging your flat bed is pretty high as well. So you'll either need to get long ramps to make the angle less steep, or find a hill or berm to park up against to lessen the angle of the ramps.
After a while I decided to bite the bullet and get an 18' car hauler trailer with diamond plated steel deck and ramps. Its a LOT lower than a truck bed, much safer to load and I can haul so much more than just my machine. We ditched the truck and towed it with a 3/4 ton van for a while (as we had kids and family to transport and vacation with). After the van wore out, we went with a Suburban. Works great! I can haul 8 people or a stack of plywood or tow the tractor, or bring logs home on the trailer, rocks, mulch, building materials, etc.... The trailer was about $2000. It's a 7000# trailer and weighs 1500#, so it has a 5500# working load. That's well within what your tractor and loader weight. You're looking at $1500 ramps that are good for only one thing, while a car hauler trailer comes with ramps, can haul your tractor with loader and possibly an implement or two as well in a much safer fashion to boot!
I think our plates and taxes are less than $100 per year. You might not even need insurance on the trailer if its not for commercial work. It may be covered under the tow vehicle.
Best to run the numbers by your insurance agent and license bureau and see what the actual cost of ownership of a trailer VS ramps comes out to be.
Good luck in your search. Not too many people are going to see it your way.
I know when we had a large tractor (8000#), and it broke, I hired a towing company with a rollback to haul it to the shop. It was about $75 for the trip. I also had them tow it home when I no longer needed it on our remote property. Again, $75.00.
