Patent number: 8677914Abstract: The invention refers to a method at a seed drill (1) or a planter for placing seeds (27) in the soil. According to the invention the steps executed are that each seed fed out is detected, its placement site in the soil is determined through detection and at least one compound (26, 28) is placed intermittently at at least one predetermined placement site in relation to the specific placement site of each seed. The invention also refers to a device (4) for execution of the method.Type: GrantFiled: December 17, 2010Date of Patent: March 25, 2014Assignee: Vaderstad-Verken AktiebolagInventor: Crister Stark

Publication number: 20120103642Abstract: The invention refers to a disc (8) for an agricultural implement (1) comprising an annular, outside a predetermined centre diameter (D) defined, soil-cultivating portion (44), a central, inside a predetermined centre 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 ? with a plane that is perpendicular to the centre line of the disc, wherein the angle ? is 5°-10°.Type: ApplicationFiled: May 27, 2010Publication date: May 3, 2012Applicant: VADERSTAD-VERKEN AKTIEBOLAGInventor: Crister Stark

Patent number: 7997217Abstract: The invention refers to an implement regulating device in an agricultural machine including at least one group of implements (4) arranged across the driving direction, thereafter cross-wise arranged support members (15) and at least one each group of implements and support members are controllable and adjustable by a power device (23). Implements (4) and support members (15) in each group are journalled in bearings at one end of at least one carrying arm (13). The power device (23) is adapted to rotate a cross-running main beam (19). The main beam is connected with the carrying arm (13) via a spring member (18) and is rotatably suspended in relation to the frame (Ia) of the machine (1). Activation of the power device is adapted to influence the carrying arm between a position for maximum sowing depth and a transport position.Type: GrantFiled: October 11, 2007Date of Patent: August 16, 2011Assignee: Vaderstad-Verken AktiebolagInventors: Crister Stark, Johan Mattsson
