Does anyone have an opinion if dual aux hydraulics is worth the extra $1300 expense on a KBX 040?
Do you have a need for them? If so then probably worth the cost.
I added my own years ago for less than that, but prices increase. I have four remotes, but only use three of them. Three have check valves, one has float.
Consider if you want check valves in the remotes or a float function. Without check valves you cylinders will leak down over time. So an implement will gradually change position during use.
Float can be really handy sometimes. Do you need it? Don’t know...
