FYI the set up is legal and safe. May not be for you but.....my neighbor is CHP truck inspector and he see no problem with this setup. Trailer has 6ft tongue, with enough room for FEL so I can maneuver without interference with rear of truck, and backhoe extends 22" from rear of trailer which is legal. If it makes you feel any better, I now have a 16' Lamar gooseneck. Perhaps I have evolved.
Never said it wasn’t legal but we would argue for days about the safety and it wouldn’t be the first time something legal wasn’t safe!
Don’t be offended because someone doesn’t agree with you or think what your doing isn’t the best approach as I’m sure there are things I have done, still do and will do that you won’t be too quick to do yourself or even agree could be safely done.
Have fun towing your tractor any way you see fit just don’t expect me to sit at the sidelines and be quiet when I think the advice your giving directly or indirectly is not good advice.
