1650 draw bar

[scarl]

Does anyone know how big of a hole should be in a 1650 draw bar? I have an egg shaped hole and was going to weld it up but I am not sure what
size it was originally.

1 1/8

The hole in my 1550 is egged out some and the 1 1/8 pin from my MoCo doesn't quite go in. The drawbar is really hard. I tried a carbide burr in a Dremmel and it wouldn't touch it.

We have a 1650, 1750, and 1755. Had the 1650 since 1977, the 1750 came around in 1989, and the 1755 in 2008 or so. All holes in the drawbars are egg shaped. I cant help on the exact size they should be. If it were mine Id find the biggest pin I planned on using, weld it up, and grind it round. Unless your doing a really good restoration I wouldnt worry about pin size as long as yours fit.

I can't say for sure on the 1650, but I have a low hour 1600 that's been on loader duty most of it's life, so there's very little wear in the drawbar. I just checked it with a mic, it's one inch.

I'm reasonably sure that the hole in the wider drawbar on my 1850 was originally inch and an eighth. The pin in the equal angle hitch on my discbine is inch and a quarter. It was wallowed out so it worked fore and aft, but I had to take a torch and trim out just a hair side to side. That pin fits the hole in the White 2-105 and 135 without alteration.

It seems like it is 1 inch on my 1650 also but that just seemed a little too small for that size tractor. Thanks for the info.

The 1850 drawbar with the inch and an eighth hole is wider, so maybe they didn't want to take out that much material by going inch and an eighth on the narrower 1550-1600-1650 drawbar? I don't know.

I welded up the hole on my 1655 a few years ago. It had worn to the point where I was worried that it would break through on the rear. My Kuhn 283 disc mower used a 1 pin, and I run that same size on my kicker baler, so I welded the hole to allow an easy slide-in fit for those pins. Probably runs close to an inch and an eighth.

I have made bushings out of hollow pipe when the drawbar gets to sloppy. You need to shape the sleeves to fit your opening oval ity. On the 1650 or any single bar hitch you can the just weld the top and the bottom and use a grinder to flatten the surface. When it wears out you just grind a bit deeper and punch it out and start again. I dont know why the manufacturers couldnt do the same thing. An expendable bushing would work great in a drawbar. My 1850 was a tougher fix as it has a split drawbar so the top bushing is welded in while the bottom one just sits in place with a large flange on it. In fact they are worn out and I need to replace them.

I am not sure but have heard that drawbar pins are sized by tractor horsepower. I think a 60 horse tractor uses a 3/4" pin. I guess the 1650 with around 65 HP would be 7/8" or 1" pin.
