I have a dumb question, the remote selector valve in the photo (# 10) seems to select between normal 3-point hydraulics and the remote hoses. At the moment the #10 lever is vertical, and the front-end loader works perfectly. The 3-point operation is nonfunctional. I am new to this tractor, and I cannot find any detail discussion in the operator's manual to address the interaction of the two functions. I tried to hook up a box blade and found the 3-point uncooperative. Please can somebody tell this 90-year-old just how I might get both 3-point and loader operation. By the way to you guys who helped me with the safety start switch in a previous post, I found the switch at reliable aftermarketpartsinc for $30.Thank You
