Abstract: Annotations for a map of a worksite are generated by a controller. The controller receives georeferenced crop state data and georeferenced agricultural characteristic data, collectively referred to as agronomy data. The georeferenced crop state data and georeferenced agricultural characteristic data are analyzed by the controller to determine relationships therebetween. The controller generates the annotations based on the determined relationships. The controller generates explanations, which are type of annotation, based on determined relationships between current agronomy data and historical agronomy data.

Abstract: Stabilized cutting tool assemblies. A cutting tool assembly for use with a reference surface includes a tool holder having a rotational axis. The tool holder is arranged for attachment to a drive source arranged to rotate the tool holder and move the tool holder relative to a reference surface. The cutting tool assembly includes a rotatable cutting tool coupled to the tool holder. The cutting tool includes a cutting surface and has a first portion and a second portion. The first portion is disposed adjacent the tool holder. The cutting tool assembly includes a stabilizer coupled to the cutting tool adjacent the second portion. The stabilizer has a bearing surface. The bearing surface is positioned on the second portion to abut the reference surface and to stabilize the cutting tool when the drive source moves the tool holder and the cutting tool to a position adjacent the reference surface.
