  • Self-propelled harvesting machine
    Patent number: 9730376
    Abstract: A self-propelled harvesting machine includes a front harvesting attachment, a ground drive with first and second drive shafts offset relative to the front harvesting attachment, first and second track roller units to which first and second drive shafts are drivably connected and which extend on both sides of the harvesting machine and a rear axle having rear wheels that are steered via a steering mechanism provided in a rear region of the harvesting machine. The first and second drive shafts are driven by separate first and second hydraulic motors of a hydrostatic transmission. A displacement volume of each of the first and second hydraulic motors is changed depending on a steering movement transferred from the steering mechanism to the rear wheels, realizing an additional moment about a vertical axis of the harvesting machine simultaneously with the steering of the rear wheels.
    Type: Grant

  • Self-propelled harvesting machine with hydropneumatic dampening system
    Patent number: 8341926
    Abstract: A self-propelled harvesting machine has a lifting device for a front attachment and at least one crawler track assembly which is provided with a damping system, and which is formed by a crawler track disposed on an axle of the harvesting machine and on either side of the axle, and the height of the harvesting machine can be changed by varying the spring travel of the hydropneumatic damping system of the crawler track assembly.
