Hydraulic problem on B1750d

Thanks for that. I was not sure if that was a lot of stuff or not since the other two tractors I've changed hydraulic fluid on both just had filters and no screens.

I read a post on another forum about someone with a similar sounding problem. The folks over there mentioned a possiblity if needing a "bypass valve adjustment." Any idea what that is, where that is, how to do it, etc.?
