Brian,
It has worked great all summer for my ditch bank flail. No issues whatsoever and the head follows the ground nicely.
I do understand what you are saying but I personally do not ever have a need to go into float with a cylinder fully extended. Some people may and yes that would present a issue. Depending on where I tied back to tank, I would have the opportunity for air to be introduced into the system.
I believe that the slot you have marked as #1 is for the optional draft control.
The 3rd lever should be in line so that there are 3 levers side by side similar to what I have pictured.
It looks like either the PTO button position has been changed or I have this picture labeled wrong. :confused3:
