Abstract
A baler for agricultural crop has a pressing channel and a needle rocker pivotably arranged at the pressing channel about a rocker pivot axis arranged in a plane that is orthogonal to the longitudinal center axis of the pressing channel. A drive arrangement connected to the needle rocker pivots the needle rocker relative to the pressing channel. The needle rocker has tying needles that are moved through the pressing channel when the needle rocker is pivoted. The drive arrangement has a drive element, rotatably supported about a drive axis of rotation; a coupling device pivotably supported about a coupling pivot axis positioned stationarily relative to the pressing channel; and a drive lever with a first end eccentrically connected to the drive element and a second end connected to the coupling device. The coupling device is connected to the needle rocker spaced from the rocker pivot axis of the needle rocker.
