Cub Drawbar Holes

Postby Ian D » Sun Feb 12, 2017 4:45 pm

Hi All
Can anyone tell me - when Cub 11 hole "U" shaped draw-bars were new - were all the holes the same size or was the centre hole larger?
I am looking for a good example draw-bar but some I have found seem to have larger centre holes?
I appreciate the centre hole will probably wear more due to towing but some seem to be genuinely larger in diameter?
Just wondered what the originals were so I know what to look for
Restoration standards are high so I am after a really good one
If anyone has a good example with brackets please let me know and we can perhaps deal!
Regards
Ian

All the holes were 5/8 inch diameter. Center hole may have been bored out to 3/4 inch, to fit a trailer hitch ball.

There maybe an alternative to a replacement drawbar. I've seen examples of inserting a carbon rod with the diameter of the hole you want (I think it's carbon) into the enlarged hole and filling the gap around the rod with weld. The weld doesn't stick to the carbon and the rod will fall out when done. Then you just grind the top and bottom flat with the drawbar and you have a new 5/8" hole.

1/2 inch copper pipe will work the same. watched a welder (as in underwater certified) do it. a little clean-up with a grinder, and you are good to go

Measure one of the other holes before you start repair. I think you will find it is 11/16.

If this is going to be a work tractor, I would leave the bolt holes alone. I have a trailer hitch ball mounted in one hole.
I have an excuse. CRS.

I realize that your question pertains to a finer point for a concours quality restoration but I just wanted to throw out there that trailer hitch balls can be found with a 5/8" shank that will fit the standard drawbar without needing to enlarge the hole. It's thinner and not as strong but it's not like the tractor will be towing at highway speeds or towing class 3 weight. I used one with a 2" ball until I picked up a universal bumper mount reciever hitch which bolted right up to the drawbar without modification. I can slide a receiver mount carrier into it as a carry-all and still use it to tow my boats, camper, etc...

The one from Harbor Freight fits. It's made to attach to a step bumper on a pick up truck, but bolts up fine, to a cub drawbar.

If you get the whole hitch it will cover the middle hole :)

My 52 is fairly unmolested just paint and required repairs. The center hole on mine is larger.
