I have one of the barbed chain style
View attachment 3094631 It works great! However, as others have posted, it is labor intensive - every pull requires an off-tractor set up. But it is effective! Only put a clevis in your towbar off the back of the tractor and chain to that. OP had mentioned drawbar and, if by that the bar across between the3pt hitch arms, that will not likely withstand the pull forces.
And related to that statement, if anyone has use for a drawbar shaped like a shallow letter C, let me know!
