A method for compacting silage in a silo includes controlling a compacting vehicle via an electronic control device, passing over the silage deposited in the silo with the compacting vehicle, exerting a compacting action along a compacting path via the compacting vehicle, and varying the compacting action of the compacting vehicle in a location-dependent manner along the compacting path by the action of the control device.

A method for assisting a distribution process by a distribution tool attached to a utility vehicle includes adjusting a position of a lower edge of the distribution tool by changing a lifting position of the distribution tool, determining by a sensor attached to the distribution tool a first distance between the lower edge and a surface region of the material being distributed, utilizing the first distance as a basis for adjusting the lifting position when the first distance has a value greater than or equal to zero, estimating a second distance from the lower edge of the distribution tool to the surface region based on the position of the lower edge resulting from the lifting position, and utilizing the second distance for adjusting the lifting position when the first distance has a value of less than zero.

A method for ascertaining a soil condition includes observing via a detection device, including a sensor, a kinematic behavior of a track drive caused by sinking when driving on a compressible underlying surface, and determining via an assessment device, including a processor connected to memory, at least one parameter characterizing the soil condition based in part on the observed kinematic behavior of the track drive.

An auxiliary steering device for a hydrostatic vehicle steering system, includes an input shaft, which can be actuated or set in rotation by a steering wheel, an output shaft for actuating a steering metering valve, and a planetary gearing. The planetary gearing includes a planetary wheel carrier with multiple planetary wheels, which mesh with a sun gear and a surrounding ring gear. The input shaft is connected to the planetary wheel carrier and the output shaft is connected to the sun gear in each case for conjoint rotation. The auxiliary steering device has an electric drive for exerting a torque on the ring gear, a braking device for fixing the input shaft, and a coupling device for producing a rotationally fixed connection between the output shaft and the planetary wheel carrier.

A method for compacting a harvested material in a silo by an agricultural working machine includes determining via a control unit a density profile which represents a target density of the harvested material as a function of a silo position or a silo portion along a predetermined silo length of the silo, controlling via the control unit compaction work as a function of the density profile, and controlling via the control unit a travel speed of the working machine during the compaction work as a function of the density profile.

A method for determining a density of a harvested material includes transmitting radar signals into the harvested material from a transmitting unit, receiving the radar signals reflected by the harvested material by a receiving unit, determining a permittivity of the harvested material as a function of the reflected radar signals via an evaluation unit, and determining the density of the harvested material as a function of the determined permittivity via a signal processing unit.

An agricultural tractor with a system for identifying downstream road users includes a control unit in communication with a user interface, and a sensor having a detection range which runs in a vicinity of a ground and which is in a direction of an attachment connected to the agricultural tractor. The sensor is configured to identify a vehicle located in the detection range or which enters therein, and then generates a corresponding message signal which is supplied to the control unit. The control unit activates the user interface based on the message signal for the output of a driver message. A free region visible from the agricultural tractor by the sensor is formed between a road surface and a lower contour of the attachment facing the road surface.

A method for silaging harvested crops includes distributing and compacting silage consisting of shredded foliage plants in a silo. The silo is then sealed and then fermented in the silo. At least one part of the silage is flushed with an inert gas after an aerobic phase of the fermentation is detected with a first sensor. The inert gas may also be introduced into the silage if a penetration of atmospheric oxygen is detected in the silage with a second sensor.

A method for assisting a compaction-appropriate distribution of harvested material in a flat silo includes providing a silo vehicle having a control unit, ascertaining a dry-substance density to be achieved via the control unit, determining a maximally producible compaction pressure via the control unit, ascertaining a maximally permissible layer thickness via the control unit for the implementation of a distribution-and-compaction process, determining a layer thickness currently being applied during the implementation of the distribution-and-compaction process in a location-specific manner via a GPS receiver, comparing the maximally permissible layer thickness and the layer thickness currently being applied in the location-specific manner via the control unit in order to ascertain a target layer thickness, and driving a regulating device of a distribution tool provided on the silo vehicle to assimilate the layer thickness currently being applied to the target layer thickness via the control unit in an automated manner.

A sensor arrangement for detecting a density of harvested crops deposited as silage in a silo includes a source of a pressurized gaseous medium and an opening connected by a line to the source and which is movable along a surface of the silage. The gaseous medium is guided out of the opening from the source into the silage. The arrangement further includes a sensor for detecting a property of the medium flowing through the line, and an evaluation device connected to the sensor for providing an output signal containing information based on the signal of the sensor regarding the density of the silage.
