摘要： The present document discloses a device for monitoring feeding of granules, comprising a duct (12, 111) defining a granule flow path; and a sensor (100, 200, 300, 400, 500). The sensor comprises at least one radiation source (101, 201, 301, 401, 501) and at least one radiation sensor (102, 202, 302, 402, 502), arranged to receive radiation from the radiation source. The radiation source and the radiation sensor are adapted to be arranged so that incident radiation from the radiation source to the radiation sensor can be acted upon by the granules. The sensors also comprise a sensor body (103, 203a, 203b, 303a, 303b, 403a, 403b, 503a, 503b), in which said radiation source and/or radiation sensor is arranged. The sensor body is insertable through at least one opening in a wall defining the duct, by a distance corresponding to at least a width of the duct, viewed in a direction of insertion.

摘要： A suspension unit for an agricultural implement, the suspension unit includes a bearing unit. The bearing unit contains an inner sleeve and an outer sleeve which is rotatable relative to said inner sleeve, and a friction-reducing member arranged between the inner sleeve and the outer sleeve. The suspension unit further includes a spring element, arranged radially outside the outer sleeve, and a holder which forms a spring chamber in which the spring element is accommodated. The spring element is fixed in the spring chamber between a circumferential, radially outwardly open groove, which is integrated with the outer sleeve, and a radially inwardly open groove, which surrounds the outer sleeve.

摘要： This document sets out a method of adjusting an agricultural implement's orientation. The method comprises recording, while the agricultural implement is travelling, a series of orientation values corresponding to the orientation of the agricultural implement in at least one vertical plane, calculating a derived orientation value based on said series of values and, if the derived orientation value is outside a predetermined range, adjusting a mutual position relationship between at least two parts of the agricultural implement that can move relative to each other.

摘要： The invention refers to a disc (8) for an agricultural implement (1) comprising an annular, outside a predetermined center diameter (D) defined, soil-cultivating portion (44), a central, inside a predetermined center diameter (d) defined, dish-shaped portion (43), with a boss-receiving, inner side and between these portions an existing, annular connection portion (45) with fastening screw holes (46). The connection portion (45) is a truncated conical portion, the inner mantle surface of which is mainly straight or double-bowed with the convex side facing said inner side and a line through the opening plane in the hole opening of each fastening screw hole on said inner side forms an angle α with a plane that is perpendicular to the center line of the disc, wherein the angle α is 5°-10°.
