A work machine determines, when a request to restart an engine is made, whether or not a reason indicated by stop information stored in a memory is a reason related to locking of the work portion. The machine sets an operation mode of the engine and a work portion to a safe mode if it determines that the reason indicated by the stop information is a reason related to locking of the work portion. The safe mode is an operation mode for lessening damage resulting from causing the engine and the work portion to work during the work portion locked or damage resulting from an object coming into contact with the work portion during the engine and the work portion working.

An agricultural planter is operable in a travel direction and a travel velocity and configured to dispense seeds into a furrow formed within an agricultural surface. An adjustment assembly is for the agricultural planter and includes a bracket configured to be coupled to a frame of the agricultural planter and a debris cleaner coupled to the bracket. The debris cleaner is configured such that during operation of the agricultural planter the debris cleaner has, relative to the travel direction, a leading edge and a trailing edge. The debris cleaner is movable such that a distance between the leading and trailing edges in the travel direction is adjustable.

A system for monitoring soil conditions within a field includes an agricultural implement including a frame and a ground-engaging tool coupled to the frame. The system further includes a first sensor coupled to the ground-engaging tool and configured to detect motion of the ground-engaging tool as the agricultural implement is moved across the field. The system additionally includes a second sensor separate from the first sensor. The second sensor is configured to detect an orientation of the ground-engaging tool relative to the frame as the agricultural implement is moved across the field. The system includes a controller communicatively coupled to the first and second sensors. The controller is configured to determine an indication of a soil condition at a given location within the field based at least in part on the detected motion and the detected orientation of the ground-engaging tool at the given location within the field.

A system for assessing the performance of an agricultural implement may include a ground engaging tool configured to engage soil within a field as the agricultural implement is moved across the field such that the ground engaging tool creates a field material cloud aft of the ground engaging tool in a direction of travel of the agricultural implement. The system may further include a sensor configured to detect a cloud characteristic of the field material cloud and a controller communicatively coupled to the sensor. The controller may be configured to monitor data received from the sensor and assess the agricultural operation being performed based at least in part on the cloud characteristic.

The automatic, rotating agricultural system rotates around a central pivot point in either a full rotation or a partial arc to irrigate, plant and/or harvest a field. The agricultural system includes a center pivot frame, a plurality of frame segments connected to each other, and a feed storage bin connected to the center pivot frame and the frame segments. The frame segment includes a section frame including wheels to enable movements, a cutter trolley beam extends in a radial direction of the section frame, a cutterhead coupled to the cutter trolley beam to cut forage or crop, a radial conveyor that moves the cut forage or crop in the radial direction of the section frame, and a cutter conveyor that moves the cut forage or crop from the cutterhead to the radial conveyor.

A method for monitoring the mechanical automated removal of weeds comprising emitting ultrasonic waves in a direction perpendicular to the direction of the soil by means of at least one ultrasonic distance sensor, determining the distance to the soil, emitting electromagnetic radiation in the direction of the soil by means of at least one radiation source, registering the intensity of electromagnetic radiation reflected or scattered there by at least one optical detector arranged on the hoeing machine, using the registered intensity to determine whether the tillage has been sufficient to lead to a removal of weeds and/or whether too much dust has been whirled up, detecting shear and/or bending stresses at individual tools using strain gauges and comparing these stresses with calibration values, detecting airborne sound waves using at least one microphone, and comparing the registered airborne sound spectra with airborne sound spectra registered in advance in the case of a faultless weed removal.
