Kuhn accumulator question

I used our Kuhn accumulator for the first time yesterday, the bale are heavier then I like. I have remove all the pressure from the bale camber but they are still a little heavy. The hay was not very heavy and I double windrowed some singled some of the heavier hay. The hay is dry,should try slower PTO RPM slower ground speed? I am running a NW 5070 hayliner
