A control for a structural assembly oscillatingly supported around a swivel axis on a base unit in a harvesting machine and including a cutter table inclinably supported about an axis of rotation relative to a conveyor channel, has an hydraulic operation cylinder. The inclination of the cutter table relative to the conveyor channel is effected by the hydraulic operation cylinder pivoted at one end to the conveyor channel and at the other to the cutter table. An hydraulically loaded relief cylinder, the pressure medium of which is cushioned by a pressure reservoir, is installed with one end to the conveyor channel and with the other end to the cutter table so as to balance a position of the cutter table relative to its point of rotation by the force of the relief cylinder.

An hydraulic elevating mechanism for lifting and lowering an engineering structure which is sluingly supported around a rotational axis on a base unit, has two or more hydraulic lift cylinders pivoted to the base unit at one end and to the engineering structure to be slued at the other. The lift cylinders are controlled by hydraulic control circuits separated from each other and such that at least one of the lift cylinders is connected to a pressure reservoir.

Hydraulic elevating mechanism for structural assemblies on agricultural

A control device for controlling a cutter table oscillatingly supported on a base unit about an axis of rotation of a harvesting machine, wherein the cutter table is inclinable about the longitudinal axis of a harvester thresher, the inclination being effected by a hydraulically operating cylinder relative to a conveyor channel. The operating cylinder is pivoted at one end to the conveyor channel and, at the other end, to the cutter table. A spring bridges the hydraulically operating cylinder and rests on one end at the operating cylinder and, on the other end, at a piston rod of the operating cylinder and is biased by a bolt nut on a threaded portion of the piston rod so that an imbalance of the cutter table relative to its point of rotation is equalized.

The invention concerns a new arrangement of the reaping platform of harvesting machines with a feed drum (2) supported behind the cutter bar (3) in the direction of travel and with, where appropriate, a reel (5) interacting with it, the bearing arrangement of the feed drum (2) being adjustable forwards and backwards in the horizontal direction relative to the cutter bar (3) and, if appropriate, being adjustable so that it can move up and down in the vertical direction relative to the bottom of the reaping platform trough (1).

Reaping platform for harvesting machines

A mowing finger for finger bar mowers of harvesting machines having first and second opposing finger parts each formed of flat material. The first and second finger parts are fixedly secured to each other to define a gap therebetween for mowing action between them. The mowing finger has a tapered front portion located forward of the blade gap and a rear portion secured to a finger bar. One of the first or second finger parts includes a twisted portion twisted around the longitudinal axis of the mowing finger and fixedly secured to the other end of the finger parts to provide increased rigidity to the mowing finger. At least one vegetation-excluding deformation is formed in the first or the second finger parts in the area of the blade gap and extends into the blade gap to narrow and obstruct the blade gap against the accumulation of plant matter therein.
