At my age I find myself unwilling to change my ways of doing things. I have planted with this tractor for 15 years and took pride in my straight even rows. The ez steer monitor I purchased years ago for spraying guidance using its light bar. I had discontinued using it for a number of years now since we changed to 30 in rows which I could follow properly. This year it was suggested to me to purchase the auto steering attachment for the ez steer monitor. After doing so and installing it I still found myself planting all my fields manually except the last one because I didnt trust it. After taking the time to adjust it and understand its operation I found myself using it and wondering why I waited so long to do so. Old habits are hard to break and I have to admit the tractor with this in operation can drive its self better than I can. Rod.
