I just bought a 25' gooseneck trailer to haul my Kubota
M6040. The trailer has a 20' deck plus a 5' dovetail section. My trailer has flipover ramps that lie flat on the dovetail. If I have the loader and a 7' rotary cutter on the tractor I have to raise the loader and pull forward so that the loader is over the gooseneck, in order to have enough room to lay the ramps on the dovetail. I then back up and put the cutter down on top of the ramps. It all fits, but just barely. The trailer is maxed out at it's 14k capacity with that load. I would be happier if I had some weight capacity left, because I don't like how the tires bulge with the weight. I think the
L5740 is a bit lighter than the
M6040, but make sure the trailer will have enough capacity for the weight of the tractor plus loader and cutter. You may need airbags on the F-250 to handle the pin weight of the trailer (will probably be at least 20% of the loaded trailer weight, which may be over what the 250 can handle without excessive sagging).
One thing I don't like about my trailer is that the dovetail really drags when you go in or out of a driveway with a steep hill. It's worse because I have an F-350 SRW, which is a couple of inches higher than your F-250. Because of our hilly driveway I have to have the gooseneck sleeve adjusted pretty high so the trailer doesn't pinch on the tailgate or bed rails, which makes the dovetail drag even more. You'll be fine if it's flat where you live, but you may be unhappy if you have steep driveways to negotiate. I think different trailers have different clearances both at the back of the dovetail and also under the gooseneck section, so it pays to investigate more carefully than I did. Some trailers have the axles further apart, which puts the second axle closer to the dovetail, which may help with dragging.
Stability towing the tractor is great with the gooseneck. I towed it 150 miles a couple of weeks ago and couldn't complain at all how it handled.
