I am waiting for my new Kubota LX3310 to arrive and just picking up a few items here and there in advance. I want to buy a twisted clevis to hook towing/logging chain to the draw bar but I do not know the dimensions of the bar thickness or the diameter of the pin holes. I have searched all over google and haven't found any direct answers for this newish model. Best guess is 3/4" dia holes and 1.25" thick bar. Anyboth have a LX2610/3310 or even their predicessors the B2650/3350 to confirm?

Thanks in advance.

Drawbars are built to standards like ASAE which stands for American Society of Ag Engineers.

According to Kubota's spec's your tractor will have a Category 1 three point hitch

I have boxed in red the ASAE standard for your Category 1 hitch that apply to your tractor.

Thanks! I didn't know the draw bars were standardized as part of the 3 pt system.

I have a B2650HSDC and I have yet to find a twisted clevis to fit my draw bar. While the specifications given above may be ASAE standards the draw bar hole size in my draw bar provided with the tractor has an inside dimension of .823. Not even close to 1 inch. I either end up with a pin that is too big if the clevis fits around the outside of the draw bar, or if the pin fits, the clevis won't have a large enough opening to go around the draw bar. I really don't want to spend upwards of $30-$40 for a 1 inch drill bit to make the hole larger, so if there is anyone out there that has found a source for something that fits, I would be interested.

That is what I had heard from a few others, but they seem to say a 3/4" with a bushing or drill to 7/8" or drill to 1". How far is the center of the hole to the end of the drawbar on yours??

How do the width and thickness measurements in the standard compare to your drawbar.?

The draw bar itself measures close enough to specs, 1.256x1.937x 15 5/16 long or 1 1/4 x 1 15/16 closest fractional sizes. The existing hole is 1" from the end of the bar to the center of the hole. I can't even put a 2 inch ball on the draw bar as it would have a 1" shaft on the ball. If I drop down on the size of the ball shank i would need a bushing or it would be sloppy in the hole. Quite the engineering Kubota has come up with. I have the machining skills necessary to put the right size hole in the draw bar, but not the tooling.

The B2650 owners manual shows different holes in the draw bar.

Can you please advise if all the holes are the same size along the length of the bar,

I am just trying to figure out is it can be installed where the opposite end is in and if so are the holes showing a different size than the ones which you find too small

re: Twisted clevis . I simply added a 2nd clevis to the 1st clevis on my forklift as well as pickup truck hitches. Somehow ,over 40 years, I've acquired a huge box full of various clevises but the only twisted one is made from 1-1/4 barstock

Thanks for posting this Dave. I've been looking for info on my L2800D's drawbar as upon purchase, it is absent. Of course I have access to universals and substandards that can "fill the void" until I track down a replacement.

Any knowledge or ability to find the part number for such drawbar's? I am told mine is a late model 2005 L2800D and would appreciate any help as the owner's manual I found online has only data like you posted above.

Thanks!
