I'm new to this forum so please excuse any in-formalities. So the problem I'm having is that the lifter cylinder on my gyramor 207 isn't holding pressure. Every time I raise the unit, the pressure will release and the unit will keep dropping. The lifter cylinder did have a bad gasket that I had replaced at the local John Deere shop, but even though it is no longer leaking, the unit still won't hold pressure. So I don't know if its a problem with just the lifter cylinder or an issue with the PTO on the tractor. I would go back to the John Deere shop, but I have been calling them for two weeks and they keep putting it off. Any suggestions or hints would be great. Thanks. I'll have a picture of the lifter cylinder attached. More pictures upon request.
