Harvesting & Technology
Technology, terminal & details
The lifting units, engine compartments and cabins of the new ROPA Panther 2 and Tiger 6 series are largely identical in accordance with the ROPA design philosophy. Werner Hofbauer demonstrates the ROPA Panther 2 and explains some of the numerous new details.
RR lifting unit
Weight-optimised RR lifter with single-row adjustment
The RR lifting unit is equipped with counter-rotating oscillating shares, seven lifting rollers, completely maintenance-free hydraulic stone protection and single-row adjustment of the lifting depth. The 850 mm large depth-control wheels combined with the intelligent three-point suspension guarantee accurate depth control of the lifter. Maintenance costs are minimised with adjustable taper roller bearings in transmissions and the oscillating share drive.
The convenient maintenance position is the best possible position for inspection and service of defoliator knives, scalper knife and lifting shares. The defoliator and lifting group can be raised to 90 degrees at the touch of a button from the cabin or the ground.
RAS leaf ejection
ROPA all-round defoliator with leaf ejection
The beet leaves are shredded and transported by a leaf scroll to the leaf plate, which spreads them over the harvested area. A press of the button in the cabin switches the machine between topping modes. An optional leaf collection conveyor can be installed for harvesting beet leaves (biogas or dairy).
PAS/RAS integral leaf-diverter
ROPA all-round defoliator with integrated leaf storage
The beet leaves are shredded and deposited between the rows. A press of the button in the cabin switches the machine between topping modes.
PIS/RIS - ROPA integral defoliator
ROPA integral defoliator - standard model for normal harvesting conditions
Leaves from the beet crowns are mulched with robust defoliator knives and spread between the rows. This process spreads the beet leaves with all their nutrients evenly over the soil, forming the optimal basis for the subsequent cultivation for quick conversion of the green waste to humus.
The comb of the Micro-Topper follows each beet head, adjusting the trimming gap to the size of the head, so that the beet is cut not too much and returns maximum yield. The intensity of the cut can be easily adjusted from the cabin. You may choose between topping and "shaving off" leaves only (micro-topping).
The both fully hydraulic driven cleaning rotors can be adjusted in the rotation speed and height independently from the other – unique! Various settings can be stored and accessed on the joystick using a memory function. Each rotor shaft can be adjusted at the height independently from the other. As a result, the operator can react quickly and effectively to different requirements due to changing beet crops. Various settings can be stored and accessed on the joystick using a memory function.
Contractor and farmer Soeren Kremeike reports on his experiences of using the ROPA Tiger 6S with rubber defoliator
Sören Kremeike operates his own farm with biogas system in Brome (eastern Lower Saxony) and serves as an agricultural contractor, who has specialized in sugar beets – from sowing to harvesting. Since 2015, sugar beet has been harvested by a euro Tiger V8-4 with a rubber defoliator. For the 2020 harvest, the team selected a new Tiger 6S, also with rubber defoliator. The choice of rubber defoliator is based on the own biogas system and the demand for this process from various customers. Very good topping results can be achieved if the setting is correct. Service is provided by Palandt.
Increased cleaning area and new turbine cleaning
In accordance with the higher engine power, the cleaning power has also been adapted in the Panther 2. The RR lifting attachment has an additional seventh lifting roller included and therefore offers a cleaning area which is over 15 per cent larger. A broadened inlet to the filter belt channel guarantees an even quicker beet flow to the enlarged turbine area. After the first turbine with a 1,740 mm diameter, two more follow, each with a diameter of 1,550 mm, before the beets are moved gently into the 1,000 mm wide bunk elevator.
Gentle polyurethane fingers guarantee high feeding capacity with short unloading times of as little as 50 seconds with a full beet bunker holding around 30 m³. The extra long unloading conveyor was based on the length and concept of the Tiger 6. The unloading conveyer is 1600 mm wide and foldable in 3 places. By basing this on the construction of the ROPA Tiger 6, the height could be further reduced despite the increased loading width - a major advantage for lifting under power lines.
The significantly extended unloading conveyor is located between both axles immediately behind the articulated joint. The driver has a clear view of the unloading conveyor without additional cameras when loading trucks driving alongside. This allows the driver to load the trucks evenly from an ergonomically relaxed seat position. The best prerequisites for relaxed and loss-free sugar beet harvest, particularly during long days and at night.
When loading on trailers driving alongside, the transfer angle is shallower. Combined with the faster bunker unloading compared to the Panther 1, this enables even faster truck loading on the move. Even 4-metre-high trailers can be loaded safely and quickly. Two separate unloading conveyor heights can be saved on the bunker control panel for even greater safety.
