hoooking 8/15 1780 to a 4440. Which way do the hyd. hoses need to back hooked up so as not to spin the fan backwards? One hose has a block that goes on the back of the tractor to regulate the flow to adjust the vaccuum amount. I think that one goes on the right side of what ever scv you want to use correct? I look in the book for a while but couldn't find much information. Thanks
