Gibson City Illinois | I have not used the ATU on my 9320 as I had the integrated valve installed on it based on my experience with a 4710 sprayer and an 8320 used for planting. I had very little in the way of success with the ATU in either of these applications, especially the sprayer. The planter tractor seemed to hunt to stay on line in tilled ground and did some better in no-till, but the inconsistency moved me to spend the money on the integrated valve and I have been happy ever since. In my opinion the big difference in the two systems is the used of a wheel angle sensor on the sprayer and on the 8320. The 9320 has one installed on the pivot point as well. It seems that the extra information from this device is very helpful to the Auto trac to keep from being as wavy. | |
