A method of operating an agricultural vehicle and charging control means

A method of operating an agricultural loading wagon (1) comprising a loading unit (2), wherein the loading unit (2) has at least one receiving means (6), a conveyor (7) and a cutting device (8), wherein by means of the receiving device (6) crop is receivable by a base, and wherein by means of the conveyor (7) by said recording means (6) collected crop via one of the conveyor (7) and the cutting means (8) at least partially limited feed channel (10) in the direction of the cutting means (8) for comminuting the harvested material is conveyed, characterized, in that a) upon detection of a tamping tool (11) in the conveyor channel (10) first, a drive for the loading unit (2) is stopped, b) relative to a load operation state of the conveyor channel (10) a curvature of the conveying channel (10) is reduced then, is raised by lifting by a drawbar of the front area of ​​the loading wagon (1), c) is subsequently turned on, the drive for the loading unit (2) for removal of the tamping tool and checks whether the pusher (11) (in the conveyor channel 10) is eliminated, d) then (after removal of the tamp 11) of the conveying channel (10) is transferred back to its charging operation state in which the curvature of the conveying channel (10) increases and / or the conveying cross section of the conveying channel (10) is reduced.
