Every header/lift cylinder/ accumulator combo is going to require a slightly different pressure to be perfectly balanced. With the header on and everything in field ready weight, without actually knowing how many psi you have in the system, you could just add or release accumulator until your header floats. Think of a spring holding your header up. If the spring is too stiff, the spring does not give and is like a solid link. If the spring is too soft, the spring compresses until it is fully collapsed and again is like a solid link. The adjustable nitrogen or hydraulic pressure allows you to find the sweet spot where the header weight and accumulator pressure are in balance at mid stroke of the accumulator volume, giving you a spring loaded header float. If you think your pressure is low, just add pressure to the accumulator until the lift cylinders start to lift the header.Have a couple of questions regarding accumulator on my R7.
First, in my manual for the L series I believe it says turn the accumulator off if you're using your AHHC. Jeff, on this forum suggests otherwise and I know he is very knowledgeable and I respect his advice. Just wondering why the old L ops manuals suggested otherwise?
Second, I want to charge up my accumulator on my R7. The kit sold by AGCO to do this does not include a Regulator. Is that because you can't buy a regulator that allows 1000+ psi through it or is there some other reason. My R7 's accumulator still has a charge but with our 3000 corn head we feel it needs more psi to stop the jerkiness when we lift it and lower it. Does increasing the charge psi make sense?
