Socket size for M59 lug nuts

[caballero59]

I can't install my wheel spacers since the tractor lug nuts are very large and require a socket that won't fit into the wheel spacer hole. I'm wondering if my M59 came with larger lug nuts (requires a 3/4" drive to get a socket large enough). I was hoping someone with an 59 could take a quick look and see what socket size their rear wheel lug nuts require. Would appreciate this very much.
