A system for detecting material accumulation relative to rotating ground-engaging tools includes an agricultural implement having a frame and first and second ground-engaging tools supported relative to the frame, with the first ground-engaging tool corresponding to a different tool type than the second ground-engaging tool. The system also includes first and second speed sensor configured to provide data indicative of the rotational speeds of the first and second ground-engaging tools, respectively. In addition, the system includes a computing system communicatively coupled to the first and second speed sensors. The computing system is configured to monitor the rotational speeds of the ground-engaging tools based on the data provided by the speed sensors, determine a speed correlation between the rotational speed of the first ground-engaging tool and the rotational speed of the second ground-engaging tool, and determine when the speed correlation differs from a speed correlation threshold associated with the ground-engaging tools.

A tractor includes: a work machine connected to a vehicle body; an elevator mechanism configured to move the work machine up and down; an electric motor; a battery; an electric leakage detection circuit configured to detect electric leakage in the battery; and a control device. The control device controls the elevator mechanism either in a lowered state or a raised state, the lowered state being a state where the work machine is placed at a position making contact with a ground, the raised state being a state where the work machine is placed at a position distanced from the ground. In a case where the electric leakage detection circuit detects electric leakage in the battery at the time when the elevator mechanism is in the lowered state, the control device performs a state change process of bringing the elevator mechanism into the raised state.

A system is presented for evaluating grain in a grain handling system. The system includes a sensor system and a sample conveyor system. In one or more arrangements, the sensor system is operatively connected to the grain handling system and includes an optical sensor. The sample conveyor system is configured to collect samples of grain in the grain handling system, deliver the samples of grain to the sensor system, and remove the samples of grain from the sensor system. The sensor system is configured to measure characteristics of the samples of grain delivered to the sensor system by the sample conveyor system. In one or more arrangements, the system includes a cleaning system configured to clean the optical sensor, the lens; and/or other components of the sensor system. In one or more arrangements, the system includes a recalibration system configured to recalibrate the optical sensor.

Described are various embodiments of a crop phenology characterisation method, and system using same. One embodiment relates to a method of monitoring a crop phenology, the method comprising acquiring a size measurement of a crop in a crop location over time, monitoring a first parameter calculated based at least in part on to a periodic recovery value of the size measurement, and a second parameter calculated at least in part based on a periodic growth value of the size measurement. In some embodiments, one or more of the first parameter and the second parameter are indicative of a crop characteristic. In some embodiments, an indication related to the crop characteristic may be provided in response to one or more of the first parameter and the second parameter.

A remote control module for a self-propelled working device has a terminal data interface for interchanging data with a mobile terminal using a terminal data protocol specific to the terminal type, and a working device data interface for interchanging data with the working device using a working device data protocol specific to the working device type. A processing unit is adapted, when the mobile terminal is coupled to the self-propelled working device, to determine the identity and the type of the terminal and the identity and the type of the working device via the respective data interface or to retrieve them from a data memory, to reciprocally translate the respective data protocols when interchanging data between the terminal and the working device, and to transmit machine control data (MCD) from the terminal to the working device and to transmit machine status data (MSD) from the working device to the terminal.
