I ordered a new Kubota with their TnT, didn't like it, replaced it with piloted cylinders from Integration Engineering, and am satisfied now. My saga is posted awkwardly on two threads:

part one

part two

My dissatisfaction with the leak down was on the sidelink during bush hogging where you normally aren't adjusting the length periodically. I don't think I would have even notice the lleakdown on the top link. Also, the 1/4 inch hose is still too fast on my tractor so I need an orifice in there as well.

I'm one of those people who changed from a non-checkvalve toplink to one with POCVs. I had large 1/2" hoses on my first toplink that ballooned slightly under pressure even though they were two-wire hoses. The cylinder would move 1/2" to 3/4" under load. I didn't notice any drift over time. My remote valve seemed to hold well. I just didn't like the non-rigid nature of the toplink and I also needed a shorter toplink by about 1-1/2" so I bought one from CCM. The difference in control and rigidity is dramatic. On this toplink, the plumbing between the POCV and the cylinder ports is rigid tubing. It does not flex. If the internal seal ever leaks on a non-checkvalve cylinder, it will also fail. Whichever, that would indicate a need for maintenance. BTW, I think I paid less for the POCV toplink from CCM than I did for the original one from Baileynet. I'm happy with the new one although I'd say you will find the one you have is a tremendous improvement over manual adjustement. /forums/images/graemlins/grin.gif

On my sidelink, I bought a TISCO sidelink from my NH dealer. It leaks down very little, and since the 3PH floats, I personally think the need for a tight control on the sidelink is not important. Of course, my primary uses are boxblading and rotary cutter. I can't really speak to any other application.
