At the Agritechnica in Hanover ROPA presents two new developments that automatically adjust the working depths of the harvesting attachment on the Tiger 6S:

• R-Trim - automatic adjustment of the defoliator height

• R-Contour - automatic share depth adjustment of the individual rows at the RR lifting unit

Both systems adapt their working depth to the changing conditions in the beet crop throughout the field. The automatic systems react to different crown heights or to ground unevenness crosswise to the direction of travel. The currently used measuring system at the scalper has been extended by an additional measuring system for recording the ground contour directly at the beet rows.

R-Trim - automatic defoliator height adjustment

A new powerful on-board computer on the lifting unit of the Tiger 6S reads all measured values within a split second and, with the aid of the newly developed software, changes the defoliator height or the lifting depth of the individual rows. The combination and interaction of both systems significantly relieve the driver, which allows partly autonomous guiding of the lifter attachment. Topping losses due to changes in the condition of the crop are avoided without stress for the driver despite the reduction in the size of cut-off leaf stalks. This prevents not only the unnecessary pickup of soil by the lifting share and increased fuel consumption due to excessively deep lifting, but also root fracture of the beet if harvesting too flat.

How does it work?

The driver sets in the menu the desired height of the defoliator shaft over the cutting height of the scalper flail (red arrow in the chart). This setting defines the average length of the stalks remaining on the beet after the defoliator knives. An angle sensor on each Micro-Topper records the crown height of each beet row. In the case of differences in the crop growth (e.g. dry areas) the activated R-Trim automatically corrects the height guide of the defoliator shaft depending on the highest beet.

R-Contour - automatic share depth adjustment of the individual rows at the RR lifting unit

The driver uses the joystick on the operating console to set the lifting depth as required and thus defines how deep the lifter share will penetrate the soil. Ultrasonic sensors beside every beet row record the ground surface contour. A new, powerful on-board computer processes the measured values and ensures that the lifting depth is maintained in accordance with the ground contour. Compared to the previous systems for automatic adjustment of single rows, this system has many advantages, particularly with higher growth in beet rows beside lanes. The activated R-Contour prevents root fracture of the beet if harvesting too flat or unnecessary pickup of soil if harvesting too deep. The share depth adjustment is displayed synchronously on the terminal.

How does it work?

The driver activates the R-Contour (ground contour sensor system) in the terminal. Thus, the share depth adapts to the ground contours. The activated R-Contour prevents root fracture of the beet if harvesting too flat or unnecessary pickup of soil if harvesting too deep. The share depth adjustment is displayed synchronously on the terminal.
