Height control system for a front harvesting attachment

A height control system for a front harvesting attachment, comprising a frame, at least one crop pick-up device, and a ground-conforming cutterbar which is situated on a plurality of supporting arms that can pivot about a horizontal axis and are articulated on the frame. The supporting arms can be pivoted, originating from a desired position to be set before the start of a harvesting operation, between an upper end position, which delimits a deflection of the supporting arms in the direction of the crop pick-up device, and a lower end position, wherein the upper end position has a first clearance and the lower end position has a second clearance from the desired position, wherein the desired position can be adapted, during the harvesting operation, to changing harvesting conditions and/or operating conditions depending on a deflection of the cutterbar, in order to minimize the first clearance and maximize the second clearance.

20210105944 · 2021-04-15 ·

A harvester is provided with a draper head that has a frame extending substantially across a working width of the draper head. Cutting elements are arranged at a front side of the draper head and connected to the frame. Conveying surfaces and conveying members transport cut crop from the cutting elements to a discharge location of the draper head. A reel extends transversely to a working direction of the draper head across the working width of the draper head. Reel support arms are pivotably supported on the frame and support the reel. A hydraulic adjusting drive is operatively connected to the reel support arms to pivot the reel support arms to carry out a height adjustment of the reel. A hydraulic circuit is operatively connected to the hydraulic adjusting drive and has a hydraulic valve that is able to lock the hydraulic circuit.

An agricultural machine includes a frame, and a lifting unit configured to vary a height of an operating unit with respect to a supporting surface for the machine. The lifting unit includes hydraulic cylinder with a liner and first and second pistons both slidingly housed inside the liner and arranged in series to define first and second chambers inside the liner, wherein the first and second pistons are controllable independently. The lifting unit includes a pressure stabilizer in fluid connection with the first chamber and that controls a pressure in the first chamber so that the first piston moves therein as a force generated on the first piston varies. A second control element for the second chamber carries out a volumetric control of the second chamber to control a position of the second piston regardless of a pressure inside the second chamber.

LOCKING ASSEMBLY FOR AGRICULTURAL COMBINE HARVESTING HEAD
20200337227 · 2020-10-29 ·

A harvesting head for an agricultural combine includes a frame and a support arm coupled to the frame. The support arm is configured to move between an unlocked state in which the support arm is moveable relative to the frame and a locked state in which the support arm is fixed relative to the frame. The harvesting head includes cutting teeth supported by the support arm relative to the frame. The cutting teeth are configured to move relative to the support arm in a reciprocating motion along a longitudinal axis of the frame. The harvesting head includes a gauge member coupled to the frame. The gauge member is configured to sense a height of the frame relative to a surface. The harvesting head includes a control assembly configured to move the support arm into the locked state based on the height of the frame relative to the surface.
