Can you provide more details on how you installed this valve? Specially how it's connected to the system? A couple pictures may help too.

An RD522, rated at 25GPM, is an awful big valve for your tractor. You really want something rated around 10 GPM or so. This will provide much better fine control over that high GPM valve.
