adding a hydraulic top link and hydraulic rear blade Kubota B3000

[blenderbender]

I wouldn't expect the top link to stay put when disconnected. You lose a small amount of fluid every time you disconnect, and that will be enough to probably let the top link wiggle a bit.

Hadn't considered this at all either. I wouldn't have thought it would be significant.

Thanks all for your considerations!

Last consideration. If you uncouple any hydraulic system with a load on it, and then try to recouple with continued load, you'll have a problem. To switch back and forth by using couplers you must have a way to neutralize the load. Otherwise you are going to be cussing your system a LOT.

Why not add a 12 volt electric diverter valve, plug in both cylinder hoses and control which cylinder is active with the electric valve.

Richard... re: "To switch back and forth by using couplers you must have a way to neutralize the load." Perhaps I don't understand 'when there is a load on it'.... if an implement, such as rear blade, is on the ground with nothing applying pressure to the blade in any direction, wouldn't that cylinder be considered unloaded?

thanks.... Gary

Yes it would. But if you uncouple the hydraulic top link for example, and then try to recouple it with the blade raised on the 3pt you will not be able to do it. You'll always have to find a neutral spot to relieve that load. You'll quickly find that isn't as easy as it sounds.

Travlitt's idea is a better situation but costs money.

Thanks... I've just discovered there is such a thing and based on what little I know, this seems to be the way to go.

A diverter/selector valve works great for this versus cost of adding second remote kit. Either electric as travlitt mentioned or simple manual control and mount it where it can be easily reached from the seat and from rear of the tractor.

Thought of a question regarding these manual diverters. Are they designed to work under load in a live circuit or must the circuits be neutralized before toggling between implements?
