I have one of those, I think, anyway it is a Vermeer 10 wheel v rake. It covers ground fast. It dows not like to make short turns, the windrows in the turns will be misshapen. I do use dual remotes. my main complaint is that when I have it adjusted to make decent windrows and raise the rake with the hydraulics, the rear wheels drag the ground which is not good if you are changing fields along a paved road. I don't think the 8 wheels have that problem. Be careful when turning near trees or posts, you can hang the rake on them.
Amusing story on the rakes: Cousin has an 8 wheel and needed an extra wheel for parts. Both of us were at a dealers and he spotted a wheel laying on the ground outside the shop. Dealer is a wheeler dealer and dosen't like to miss a sale, so he made my cousin a good $20 price on the used wheel. I hadn't gone there expecting to get a wheel, but I could have used one. After cousin and dealer finished the deal and money changed hands, i noticed a as new wheel leaning against the building, in plain view, cousin hadn't seen it. I asked the dealer about the good wheel, and he sold it to me for $25. The look on cousin's face was priceless, if he had noticed he would have bought both of them.
