A device for the deaeration of a hydraulic fluid of a hydraulic system has at least one hydraulic motor arrangement and a hydraulic fluid storage which is hydraulically coupled with this hydraulic motor arrangement. A suction device for sucking out the hydraulic fluid is associated with the at least one hydraulic motor arrangement such that the suction device guides hydraulic fluid out of the hydraulic motor arrangement into the hydraulic fluid storage by means of vacuum pressure (&#x394;p). The suction device is constructed as a jet pump and is integrated in the return line between the hydraulic motor arrangement and hydraulic fluid storage.

Loading vehicle structure

A round baler for baling harvested crops has a loading device which receives a roll of wrapping material which can be transferred to an unwind station. From the unwind station a web of material is pulled off the roll for wrapping the bale. To install the roll of wrapping material serviceably and without great effort, the loading device is pivotably installed on the baler's sidewall. The loading device is pivotal from a storage position to a transfer position, so that the roll of wrapping material can be pushed from the loading device into the unwind station.
