I've not seen one like that, but that doesn't appear too substantial and it appears closer to the tractor than I would prefer. Maybe the pics are deceiving. Here is what I am familiar with. PTO Swinging Drawbar — 30in. Length | 3-Point Drawbars + Stabilizers | Northern Tool + Equipment
Edit: I didn't notice this was the Kubota section. I may be giving you bad information, as I'm not familiar with that tractor. I would THINK you could use a standard drawbar like I posted, but I could be wrong.
its right freakin under the pto shaft ! in fact the parts look up at the bota dealer even shows the pin going up instead of down because it wont clear the shaft.
In my owners manual it shows an "optional" swingbar for this tractor but I cant find one anywhere
