Patent number: 10051789Abstract: A side-delivery rake comprising a frame provided with at least a supporting arm to which a plurality of stellar wheels are associated. The supporting arm is pivoted to the frame so as to assume, by means of rotation around a pivoting element, at least a first working operating condition in which the stellar wheels carry out a gathering action, and a second transport operating condition, in which the stellar wheels are in a raised condition. Stop means are provided to determine the position of the supporting arms in the first operating condition. The stop means comprise an adjustment device which can be selectively associated with the frame in a finite plurality of predetermined discrete positions in order to define an adjustment of the position assumed by the supporting arm in the first operating condition.Type: GrantFiled: December 18, 2012Date of Patent: August 21, 2018Assignee: Tonutti Wolagri Highlight S.R.L.Inventor: Carletto Tonutti

Publication number: 20120031065Abstract: An agricultural machine to rake a mass of hay, or other agricultural product, including at least a trailer-mounted frame, and an arm on which a plurality of operating tools are rotatably mounted. The arm is constrained to the frame so as to selectively move between a first operating condition in which the operating tools are in cooperation with the ground, and a second inactive condition in which the operating tools are raised from the ground in a position substantially parallel to the ground itself. The agricultural machine includes articulation members, interposed between the frame and the arm and includes a first positioning portion attached to the frame and a second positioning portion to which the arm is constrained. The first positioning portion and the second positioning portion are pivoted with respect to each other by elements of an articulation pin, in order to move the arm between the two conditions, operating and inactive.Type: ApplicationFiled: April 22, 2010Publication date: February 9, 2012Applicant: Tonutti Wolagri Spa Con Socio UnicoInventor: Carletto Tonutti
