Sorry for the delay in getting back to this thread. First time I have had to work on the tractor. Switched the relief valves over from my old pump to this one and mowed the grass again. My observations are that when it is cold for the first 5 to 10 minutes of mowing everything is fine then as it warms up, it starts to do the chatter thing. It only does it at one speed going up a slight incline. If I give it more or less ground speed it goes away. Next thing is changing the fluid I guess. Anymore thoughts?
