Hyd Accumilator

[TomG]

No, not boring at all. Anything that helps me thing this stuff through is good.

Where I was coming from is trying to think through how tractor hydraulics would perform with an accumulator that is large in relation to the pump. I thought that quite a fair amount of force would be lost when the system operated with depleted accumulators. I also thought that the way tractors are used creates very unpredictable demands, and only the use of large accumulators would ensure that something close to max system pressure was maintained. I wondered, and still do, if that would be good design for a tractor.

Mine was a think piece. I agree with Roy that everything said so far is true. All this stuff is helpful to me, and I hope others as well. Sort of like the safety subjects. I think it's really important to get how this stuff works firmly in mind.

TomG, personally, I think a little cool down time is good for any engine all right, but it was more critical for a lot of turbos.

A hyd acc is used on the deere to provide back-up hyd pressure after you turn off the engine.It is used for the brakes mainly so you can Use the brkes several times if you have to with the engine off or if it dies and you have to stop.
