Next-level hydraulic concept
The working hydraulics of the Keiler 2 RK22 have been completely redesigned for even more responsive control of all drives and functions as well as increased drive power. The Keiler 2 is unique among all tractor-towed implements thanks to its fully hydraulic drive of all separation systems, conveyors and chains in conjunction with an internal, electronically controlled load-sensing working hydraulics.
Designed for long life, this construction is precisely controllable and ensures increased harvest quality while saving fuel and resources.
ADVANTAGES OF FULLY HYDRAULIC MACHINE DRIVE
■ all drives are supplied by axial-piston pumps with variable displacement volume
■ All cleaning units maintain their optimal speed independently of the PTO speed
■ all cleaning units are steplessly adjustable in speed
■ fuel-saving and resource-conserving due to reduced engine speed
■ operational safety with reversible sieve conveyor 1 or lifter chain
■ reversible trash conveyor for direct return of the admixtures into the sieve conveyor 2, while the right discharge chute retains its function
1. Connection to the tractor
2. PTO shaft
3. Power beyond connections with load-sensing control line, coupled to the tractor
4. Axial-piston pumps for all drives
5. Electronically controlled load sensing working hydraulics
The visionary hydraulic concept offers precise electronic load-sensing hydraulics to the tractor with responsive control and therefore greater working safety.
The Keiler 2 RK22 contains new, patented hydraulic components, which are used for the first time in series production of a trailed implement.
The tractor hydraulic system supplies oil to the potato harvester only when the hydraulic power is required. The electronic load-sensing system regulates the quantity required to match the demand. Compared to standard hydraulic load-sensing systems, the function-dependent intelligent control of the hydraulic pressure on the tractor minimizes vibrations in the hydraulic system of the harvester and significantly improves the precision and controllability of the working functions. Lower tractor engine speed saves fuel and resources. The hydraulic system can be individually adapted to the various requirements of the implement and work process by different characteristic curves.

Harvest management made easy
The potato bunker scale records significant data for the crop volume in high quality with 6 weighing cells of the latest generation directly on the harvester in the field. The data obtained can be used for the traffic-safely loading of transport vehicles and initial yield assessment. Moreover, the data can be automatically transferred to the season, day and order counter and stored.
Measuring on slopes can also be carried out without any problems thanks to the interaction between the bunker scale software and the slope inclination sensor.
The weighing system can quickly and easily perform a zero balance (tare function) at the push of a button to ensure the accuracy of the scale even after having harvested many hectares.
- 3 weighing cells on each side
- Yield monitoring directly in the field
Maintenance & service
Perfect accessibility to all belts, drives, and rollers
- Smart machine design with easy-to-maintain open construction
- Integrated diagnostic system
- Bearings, bolts and components conform to DIN standard
Multi-purpose, also for special crops
Onions
On many farms in Germany, onions have become increasingly popular in recent years. Depending on the variety, onions are harvested from June to September and left to dry in a swath. The dried onions can then be picked up and stored. The high-performance ROPA Keiler with swath pickup enables easy, gentle and efficient pick-up of onions. Thanks to the ROPA quick-change system that comes as standard, the pickup of the Keiler can be changed between the ridge pickup and the swath pickup within a few minutes.
Carrots
The ROPA pickup can be used for gentle and easy harvesting of carrots, no matter if it's a single row, a double row or a ridge. The individually configured pickup can be equipped with single or double carrot shares to harvest the second most popular vegetable in Germany without damaging the crop. Optional brush rollers ensure that the carrots are transported smoothly and particularly gently inside the machine. The continuously adjustable cleaning units can be perfectly adapted to the specific conditions of harvesting carrots.
Celery
The Keiler, equipped with an individual special crop pickup or, if the row distance is suitable, with a pickup without a ridge roller, perfectly copes with the difficult conditions of harvesting celery. The weather and soil conditions can be particularly challenging during the harvest period from September to November. But due to its high cleaning performance, the ROPA Keiler 2 can also be used for harvesting celery. The advantages of it are not only saved costs which an additional harvesting machine would require, but also extended operating time of the Keiler and reduced production costs. Each special crop pickup is equipped with the ROPA quick-change system as standard and can be individually configured.
