Dang nut fell off

[BlackRaptor]

Driving the tractor home last night from my parents farm i noticed one of the large nuts that holds the loader together is missing.
the one thats missing is the lower one that holds that bracket on, The bracket is the one that holds the loader up when you take it off the tractor.
Anyone know what size nut these are? I was going to ask a friend to grab one after work on his way to my place because by the time i get off work the hardware store is going to be closed.
Thanks.

Not sure about the size, but while you're fixing it, be sure and check and re-torque all the loader nuts according to the torque specs. in the manual. I had one on one of the pins that was loose enough to fall off. Fortunately, I noticed it as soon as it happened and found the nut in the grass.

While you have the torque wrench out, it's recommended that you re-torque the wheel lug bolts after 10 hours too, I think.

Thanks for reminding me, I just switched tires and I need to make a note of that and do it at 10 hours from now.

Just a shot in the dark - don't be surprised if the nut is Metric. For example my wheel lugs are 22mm head size.

Got it replaced with a locker nut from JD. cost 95 cents
Going to replace all of these with the locker style so I don't have to tighten them as often.
