Thanks guys.....was hoping to hear from you two! Going to change filter and clean screen first then if necessary try the stroke control valve. I did have an an opportunity for hydraulic oil contamination when I used a rear bale carrier with a hydraulic push off a couple of months ago. Friend of mine had the carrier borrowed and returned to me on a trailer with the hoses off for transportation reasons. Could have gotten some trash in the hyd oil when it was hooked back to the tractor.
Thanks again guys! gwece
