I just recently purchased a used TL8, a brush mower and a bucket grapple. Like you, I am struggling with getting the auxiliary hydraulics to work properly, but some of it could be the way I'm using it. Basically, it works sometimes, using the slider switch or buttons, and other times I get no hydraulic response at all. I have it set on one way flow, I believe. Curious to see how others set theirs up.Has anyone had experience running a low flow brush mower on a TL8 ? There's so many options I don't know what settings to use. One way flow, two way flow, and 4 different auxiliary hook ups ? Thanh's in advance if anyone can help !
