Publication number: 20220095523Abstract: A towed or semi-mounted agricultural machine having a chassis on which an axle device connecting two wheels to the chassis is mounted, this axle device being provided with at least one movable part and one fixed part in such a way that the spacing between the wheels can be modified, at least one of the wheels being integral with a movable part that is connected slidingly along a longitudinal axis to the fixed part, which is integral with the chassis. Each movable part is additionally connected mechanically to the chassis by a respective articulated link, which is articulated on the one hand with the movable part by a first articulation and on the other hand with the chassis by a second articulation.Type: ApplicationFiled: September 28, 2021Publication date: March 31, 2022Applicant: KUHN SASInventor: Cédric HALTER

Patent number: 10045480Abstract: An agricultural machine including at least one working tool which can be driven by a drive mechanism which can have a variable drive speed, at least one movable shield which can be moved at least between operational and non-operational positions, and a device for moving the at least one shield, including at least one adjusting actuator and a device for locking the shield. The movement device includes a circuit for controlling the actuator which includes the locking device, which circuit automatically converts a variable input quantity into a control quantity which can adopt a first control value used to prevent the adjusting actuator from being moved out of a first configuration, the input quantity being a value which is a function of or dependent on the drive speed of the drive mechanism or on the working speed of the at least one tool.Type: GrantFiled: May 4, 2015Date of Patent: August 14, 2018Assignee: KUHN S.A.Inventor: Cedric Halter

Patent number: 9408340Abstract: A coupling device for an agricultural machine including a support for hitching to a tractor and at least one arm articulated to the support and protruding from the support in a direction parallel to a direction of advance of the tractor, the arm carrying, in an articulated manner, a chassis carrying a work element having a cutting angle relative to the ground to allow fine control of the cutting angle during movements of the work element. The coupling device further includes an upper connecting-rod, a lower connecting-rod, and a central connecting-rod, each of the upper and lower connecting-rods is articulated to the support and the central connecting-rod to form, projected in a vertical plane parallel to the direction of advance, a deformable quadrilateral, and the central connecting-rod is articulated to the chassis. An agricultural machine can include the coupling device.Type: GrantFiled: June 5, 2013Date of Patent: August 9, 2016Assignee: KUHN S.A.Inventors: Cedric Halter, Joel Wilhelm

Patent number: 7610741Abstract: A mower includes a support structure on which are articulated about substantially horizontal axes at least two mowing units each including a frame carrying at least one cutterbar and one conveyor belt, which mowing units can be moved about the axes from a working position to a transport position. The conveyor belts are articulated relative to the cutterbars about conveyor belt axes and the mower further includes a mechanism for automatically moving the conveyor belts about their axes of articulation to bring them closer to the carrier frames and consequently to the middle of the mower when placed in the transport position.Type: GrantFiled: April 26, 2006Date of Patent: November 3, 2009Assignee: Kuhn S.A.Inventors: Cedric Halter, Martin Walch
