I am going to replace the accumulators on the TLS on my 7720, both are weeping oil out the pressure caps and are no longer letting the suspension move.

I am going after market at this stage, should be 60% of JD. RE306377 AU$930

So my question is what pressure should they be pre-charged too.

Thanks KWO

Depends on the header. JD has a chart that recommends pressure with size/weight of the header. If you have more than 1 head used, you may need to fudge between the two.

I unfortunately don't have that chart available, sorry. Something in my memory says 1200psi, but that could be completely wrong--or a different model.
