Basically this is my problem sitting there not running or touching the machine, note the clock for reference. It does it with all my impliments, even the small LPGS that's a foot to narrow. When its sitting there off you can hear it creaking every minute or 2 as it settles down. With nothing on the QH it will do it overnight with just the 40lbs? weight of the QH. Frustrating that this is a standard issue on Kubotas premium line of machines & they are incapable of fixing it.
Need to check if I can reach the QD from the seat. The manual valve is going to be the cheapest option but will irritate me the most reaching back to open it every time i want to use tilt. DPOV probably the next cheapest but kills float. Followed by an electric solenoid valve as the most expensive but keeps float if I want it.
Not to derail the thread to much. But in short you should expect a hydraulic cylinder to stay mostly put for most of a day. Taking a machine in for a several valve replacements is unreasonable behavior. Taking it in once may be a bother to the dealer, but is reasonable for a customer.
On Gannon box blades, at least manual ones if the lever isn't fully up, the latching mechanism won't engage. If that latch isn't engaged, the rest of the mechanism can't take the force & mangles itself. I'm 90% sure the hydraulic design is the same, except it has a cylinder rather than a manual lever running the show. Get that valve fixed so you dont break things.
A quick diagnostic... if you unplug the hoses & things leak down you have a leaky hose, QD or cylinder & a puddle somewhere. If it doesnt leakdown, the problem is on the tractor. QD, hose, or most likely internal leakage on the valve. As they are very precision metal spools in very precision bores, you can't replace seals, really only the whole valve.
