Mine does the same intermittently and I have all brand new cylinders. Been told it is likely in the regenerative circuit of the SCV whatever that is. Hasn't done it in a while but I was told to try cycling the curl back and forth a few times and that seems to fix the problem.
I have seen some tractor OEM cylinders with a simple Buna rubber oring/backup for an internal piston seal. IMHO Very poor excuse of a piston seal from factory equipment. In this situation we have had great success changing to a polyurethane type seal that can handle higher pressures, heavy duty and still fit in the same seal groove.
