Having trouble with header going down after climbing a terrace. Have installed latest update replacing cable linkage with rods and different pot. Helped some but still not right. 25' header is on 2388 both 2001 models. Had same trouble with 1997 model 2166 with 20' head. Running 5-6-mph in soybeans, if you slow down to 3-4 mph going over terraces seems to give it time to repond. Am I running too fastIJ Also have yet to figure out what the outside knob does on filed tracker settings
