Look at where the axle is at on these scrappers, at the VERY back. I do not see how you could get negative tongue weight with this scrapper. Philip.
In my area I have seen semi mount plows, mower conditioners and a land plane using the 3 point hitch (or at least the lower links). I also know a farm who has a screen that mounts to the 3 point hitch to protect the back window of the cab when they mow corn stubble with their 15' rotary mower.
Otherwise, I haven't really seen much use being made of the rear 3 point on larger ag tractors.
As for towing with it, I will use it to move stuff around and to tow the rollbar rake (that way I can lift it up at the end of the row), but for any "real" towing (such as the OP is describing with a dump trailer) I would not use it.

Man this thread has gotten a lot more responses that I thought it would. Looks like the group is about split in 1/2. Some will pull with the 3 point and some will not.
Thanks a bunch for the info. Some have described pulling loads that match what I have in mind.
I regularly pull (via the 3PH and a hay spear with a 2-7/16" ball welded on the top), my tandem axle gooseneck, hay wagons in tandem on the drawbar (double tandem axle Geihl's with flat racks refitted) and everything in between and most times (unless empty) they weigh appreciably more than either of my tractors.
draw bars are where they are for a very good reason... low centre of gravity. This not only helps prevet tipping of tractor, but also increases traction as the transfer of weight is along the bottom of the tractor.
