The serrated disc with a diameter of 52 cm can be used in different situations. For working depths up to 15 cm, it reliably penetrates the soil. The serrated cutaways allow for an excellent incorporation of high amounts of straw. The serrated profile almost completely prevents the discs from stopping even in very light soils. Small disc diameter for high rotational speeds and a high production of fine soil.
The CoverCrush disc is ideal for a shallow use up to 8 cm. Due to the large contact area, a lot of material is crushed but is only mixed in to a limited extent.
Due to the flexible rings, the self-cleaning effect of the RingFlex packer is excellent. Moreover, it produces a lot of fine soil. The high weight of 200 kg/m also guarantees a very good consolidation.
The double RollPack Packer is ideal for light and medium soils. The large contact area and the excellent consolidation are due to the wide rings and the low packer weight.
The end-to-end Crossbar in front of the discs of the Joker RT is ideal for an additional levelling for example when preparing the seedbed. Depending on the conditions, the Crossbar can be retracted or extended flexibly via hydraulic cylinders and the aggressiveness can be adjusted.
(Not for Joker 10-12 RT)
The hydraulic depth adjustment allows the farmer to react quickly and easily to changing conditions. An important feature especially on heavily changing soils or if used on several farms.
The knife roller of the Joker RT guarantees safe cutting diagonally to the direction of travel. The knives that fit tightly to the roller reduce the risk of breaking them to a minimum. Due to the hydraulic pre-stressing and the overload protection, stony soils are no problem at all.
