D-14 drawbar problem

I have a D-14 with a loose drawbar. The bolts going up into the tractor that holds the assembly that the drawbar attaches to are loose and can't be tightened. We have had this tractor for many years and it has always been loose. The bolt holes are worn I think and can't be tightened. I have seen other D-14s with this problem.

I need to get this fixed in order to use a mower I have. What is the best way to fix it? I don't want to weld it but I a don't know what to do. I have taken a picture of the bolts I am referring to.

The parts book doesn't list the size, but it looks like it should be a stud and nut. The drawing for the snap coupler vs the standard hitch show 2 different ways to mount the brackets, but shows the brackets being the same part number. I'd start by taking the bolts out and measuring the depth of the hole. I wouldn't weld on the cast housing unless I had to. Helicoils would be a better option if the threads are pulled. Book does say it's a 3/4" hole.

You need to remove everything and get a good sharp 3/4" NC bottoming tap and rethread the holes as deep as they will go. Clean them with brake kleen and blow dry with compressed air. You need hanger brackets that don't have the holes all wallowed out and are flat on both sides like yours probably are not. You need to use a Grade 8 bolt as long as possible to make use of the 3/4" holes full depth. You also need to use HARD flat washers instead of those soft washers. Using a bolt a bit longer and fine tuning the length/depth with hard flat washers underneath the bolt head is fine. They should be heavily loctited and torqued to at least 150 ft lbs and 200 ft lbs if the threads are good enough. Not all D-14's have this problem. Same bolt size used on D-17 thru series 3. Only tractors that the drawbar gets abused and the operator doesn't keep things tight once they work loose. Gr 2 or 5 bolts don't work. Good luck.
