I have a John Deere 3038. My 94 yo Mom lives 15 miles away, most of it is moderately heavy traffic (about 5-6m. heavy 4 lane traffic). I don't have a trailer (don't want to rent truck&trailer, rather pay someone to do the work). I have a bush hog, she has about 15 acres really needing cut. 3 ft. pines growing all over it).
Top speed is about 12-13mph. Would you drive it over there?
If all back roads or 5 miles I'd do it without question.
Here are suggestions.
First, if you can borrow a trailer, do so, Your tractor is small enough for nearly anything with 2 axles.
Second, try traveling during an "off" day and/or hour. Sundays may be the best travel time.
Third, if you drive it, ensure your tractor flashers and headlights are working.
Fourth, if you drive it, use a following chase vehicle. Be SURE to add a SMV sign, plus a flashing light
on top of the chase. Follow reasonably close, but not unsafely, to the tractor so that a passing vehicle can do both at once and the distance is minimal. At your slow speed passing time will be minimal anyway - just don't force a passing vehicle to pull between the two of you because spacing is so great.
Comment: I have no idea why anyone would not recommend a chase vehicle with something traveling less than 15 mph. I add the following note. I once hired a huge tractor & double scraper combo to do some work for me. The monster was 16 feet wide and as tall as a semi. He told me he has traveled more than 500 miles at a time on highways with it - all at 19 mph max. He told me that he used to have a flasher on his tractor and would travel alone. But on a whim, once he had his dad follow him in a pickup with a flashing light on the roof of the pickup. He said the response by passing vehicles was so much better that this became the only way he would travel.
