Centre county Pennsylvania, USA | Jim, we are using Starfire/Itc with SF1 correction on a Deere 9510 combine for yield mapping only, not autotrac for cutting guidance. Ground tracks logged by that Starfire with Itc (Internal Terrain Compensation) and SF1 correction while harvesting are deviating from straight by less than 12 inches. I think autotrac for cutting guidance would perform at least as well, and probably better because combine driver is not in the steering loop for autotrac steering. |
