Today my 20-20 would beep but when I look at the monitor, it says all are planting. Some times it would show all rows failed in black letters for a second or 2 at the bottom of the screen, then go back to normal. A normal failed, not planting row shows red. The map shows no skips or not planted areas. I was told that the map paints seeds and should show a skip or not planted row if there is a problem. Seemed to be worse early to mid afternoon. If I speed up, it got worse, slow down, better. Whats going on and how do I fix it? Am I wrong to think that if the map does not show a skip or failed row, its planting ok ?
