Took a little time set hydraulics in dozer and hooked Blade up. Still need to adjust mixing channels. I have the prv set at 20 bar as suggested by Joe. I think he's right that is lots of pressure. Still need to tidy up hoses but it's all coming back out for paint. Here's a vid of working hydraulics in dozer.
