Can I see some pics of brinley and slot hitches?

[StWeiler 6]

I can't seem to find any literature on the 'how to's' of hooking up a brinley or slot style hitch on the back of a B series tractor. Trying to figure out how a person would raise/lower the attachments for one. Also, how the belt/link routing works. Just plain ignorant on these things and need picutres to make it more clear. I've tried to find a manual, and cannot seem to locate squat on the B80

TIA
