Hello, I recently purchased an 81 Kubota B7100 HST and I am in the process of changing the fluids and filters. I have downloaded the WSM for the tractor and it came with the illustrated parts list so that is great too. They are really helpful. The only thing I am not very clear on is getting this drain plug on the bottom of the radiator to open. The lower radiator hose looks good and I can see it will probably be a mess if I take that off, so I would rather just drain the radiator with this plug if I can, but I don't know how to open it. If anyone has drained the radiator through this plug any insight on this would be great.
Thanks for your time!
