Might copy something in here I posted a while back.
Who needs ramps if you have a front end loader. I drive the JD with the front tires within an inch of the back of the trailer. With a flat bucket down on the trailer I keep going down with the loader until the front wheels are above the trailer. Then curl the bucket making the tractor roll forward until the front wheels are on the trailer and lift the bucket. Tractor will be in neutral or you can slow ahead as you curl the bucket. The weight of the front of the tractor will push the back of the trailer far enough down that I can drive up to it and the back tires just bite and drive it on the trailer. The back of my trailer has round bar where the ramps attach to so the back tires aren't biting on anything sharp. Works for me. Might depend on how heavy or how big the tractor is probably as it probably wouldn't work for a small tractor.
