A trailed implement includes a tongue coupled to an implement structure and configured for attachment to a rearward end of a tow vehicle. A proximity sensor is positioned to detect data related to objects located within a field of view disposed forward of the implement structure. A controller configured to identify a rear ground engaging element of the tow vehicle from data sensed by the proximity sensor, determine a location of the rear ground engaging element of the tow vehicle relative to the implement structure, and communicate a vehicle control and/or and operator warning signal when the rear ground engaging element is within a pre-defined distance of the implement structure.

A method of calibrating grain loss on an agricultural machine harvesting crop may include initiating a first calibration process of a grain loss monitoring system on the machine and executing the first calibration process by receiving sensor signals from sensors on the agricultural machine and a grain loss measurement based on an analysis of a harvested area in the field. The method may also include adjusting a machine setting on the agricultural machine based on an output of the first calibration process and monitoring grain loss after the setting is adjusted to evaluate the effect on grain loss of adjusting the setting.

Generating a desired position for a first vehicle from a next position of an implement attached to the first vehicle is described. A current position of the implement is obtained. The next position of the implement is identified. A desired position of the first vehicle is derived from the next position of the implement. The desired position and the next position are such that when the first vehicle is at the desired position, the implement is at the next position. The next position of the implement may be based on a position of a second vehicle. In an example, the first vehicle may be a tractor, the implement may be a grain cart, and the second vehicle may be a combine harvester.

A baler implement includes a bale formation system defining a baling chamber configured for forming crop material into a bale having a cylindrical shape, and a roller configured to apply a compressive force against the crop to form the bale. A bale size sensor is operable to sense data related to a diametric size of the bale within the baling chamber. A baler controller determines a current diameter of the bale during formation thereof within the baling chamber, and determines if the current diameter of the bale is equal to a pressure release diameter threshold. When the current diameter of the bale is equal to the pressure release diameter threshold, the baler controller may automatically control the bale formation system to decrease the compressive force of the roller applied against the bale to prevent overloading and damaging bearings of the roller.
