Planters White air planter

[deere755]

I was offered up to 8 White air planter units this week. I can buy them right or I feel I can. I am told the air is ran off of electricity so that would be no problem to hook up to my 755 but I am not sure how to drive the planter unless these units have a press wheel like the deere 71's do. I have not seen them yet but I may take a look at them. I figure farm with junk may know a little about these planters. I have heard that they were real accurate planters. If anyone can tell me about them I would love to hear what you have to say. I am thinking that if possible I would like to make a 1 row for my CUT.
