KEILER 2 RK22 DOUBLESELECT
DoubleSelect - the highest separation performance
An additional triple UFK on pintle belt 2 can significantly increase the separation performance on cloddy and stony soils. The Keiler 2 RK22 DoubleSelect is optionally available with an additional sorting platform and a trash track. This equipment is also available in combination with an XL or overloading bunker. Alternatively, the DoubleSelect is also available in a 3 meter version without a trash track and a sorting platform.
All functions of the RK22 separation unit can be conveniently adjusted from the cabin as usual. In addition, a further terminal is installed at the rear sorting platform. Thus, a wide range of machine settings can be conveniently adjusted from here.
Focus on increased separation performance
Early separation of clods and stones in the crop flow significantly reduces damage to the potatoes later on, thus ensuring that the potatoes are harvested even more gently. Each UFK can also be optionally equipped with revolving brushes (UBK).
Belts & rollers - for clumpy and stony soils

An Extra Level of Separation Performance
The separation unit that makes the difference!
The height, angle, and rotational speeds of the double and single UFK rows can be adjusted independently, enabling optimal adaptation to varying soil conditions.
Early separation – greater quality
In regions with a high proportion of stones and clods, potato harvesting places exceptional demands on separation technology. This is precisely where DoubleSelect proves its strengths.
The additional cleaning stage separates clods and stones early in the crop flow, reducing subsequent damage to the potatoes and promoting a gentle harvest.
Separation in a class of its own
Rather than pressing soil and stones against the tubers, they are actively loosened and discharged. The result is significantly cleaner produce, less damage, and a noticeable reduction in the load on downstream cleaning components.
This makes DoubleSelect the ideal solution for regions where stones are not the exception but the norm — powerful, reliable, and perfectly suited to demanding operating conditions.
The benefits at a glance
Increased separation performance:
The early mechanical ejection of clods and stones improves cleaning efficiency and enhances harvest quality — particularly in heavy, clod-prone soils.
Reduced labor requirements:
In many operating situations, harvesting can be carried out with fewer sorting personnel — or even none at all — saving costs and simplifying operational planning.
Modular design:
DoubleSelect can be configured individually to meet specific requirements — whether UFK, UBK, mixed, or optionally with or without an additional trash track.
Consistent power requirement:
The DoubleSelect separation unit requires no greater power input than alternative deflection rollers.
