SW Wisconsin
I have a NH 8670 that today when I was out using my field cultivator the air filter flow light would come on. If I backed off on the throttle the light would go off. I replaced the inner and outer air filters, checked the air inlet to the filter housing. The new filters didn't help the problem. Could it be a bad flow sensor? Or looking for other ideas.
