A utility vehicle for compacting a stored harvested material by driving over a surface of the harvested material includes a radar sensor configured for ascertaining a density of the stored harvested material by sending radar signals in a direction of the harvested material and receiving radar signals reflected on the harvested material. The radar sensor is arranged on a support device which is movably mounted on the utility vehicle and can be set between a transporting position for the radar sensor and a working position for the radar sensor which is lowered relative to the transporting position.

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.
