Case 630 Drawbar

RJKeith · Mar 10, 2014

I picked up a 630 last year with no draw bar. Finally got around to going to a steel yard and getting a 2"x38"x3/4" piece of steel for the draw bar with a piece welded to the bottom to stiffen it.

Yesterday looked under the tractor to see what size pin to use, it measures 1-1/8". With 2", that leaves 7/16 on each side of the draw bar hole, which doesn't seem strong enough. I am considering a bushing for a 3/4 or 7/8 pin. Does anyone have a 630 who can tell me what I need to do? Thanks and sorry for no pictures.

My drawbars for my 430"s are 2.5"wide x 1-1/8" thick. The B series tractors had drawbars similar in size to what you bought, and I have yet to see one that hadent been broken and welded up.

How about one of these? Eagle Hitch Drawbar.

The 1-1/8" pin is probably a little over engineered for 30-50 hp tractors, but......by the time you design and implement your bushing setup, you might be better off securing a bar that is closer to the standard dimensions Loren provided.

Thanks Loren. This draw bar would get in the way of the PTO shaft I think. But the other dimensions are interesting. The extra half inch means 11/16, almost an inch, of steel on each side. That would work, but I think I was looking at a B series to verify dimensions. I should be OK with the lighter draw bar as I would mostly be haying, no trailer plows or heavy disk.

Just mounted the one John posted here this after noon on my 411. Did you use the stock link for this version Loren?

Since we're on the subject is this the correct drawbar for a 310B?

That's a VAC drawbar, don't know if it fits others though.

Chuck,
The factory Case 3pt draw bar on my 300RN is all factory equipment.

I used a broken drawbar from a LA,500,600,900 or 930. They have a long drawbar that is frequently found broken at the drawbar support where the roller is welded on. There is plenty of straight drawbar left to make a good drawbar for a 630. A 630 drawbar (and the rest of the Rock Island tractors) sticks back quite a ways unsupported. You want to make it out of good material and make it long enough that the PTO geometry is correct.
