Horsch Joker RT disc harrows

Name: Horsch Joker RT disc harrows
Brand: HORSCH
SKU: ASTRA-01273

Manufacturer:

Horsch Joker RT harrows are ideal for shallow stubble cultivation to stimulate volunteer germination, break capillarity, mix in crop residue and prepare the seedbed surface.

The Horsch Joker RT disc harrow produces a large amount of fine soil in the germination horizon and is highly insensitive to blockage in large amounts of crop residue, organic fertiliser and catch crops.

The Horsch Joker RT disc harrow delivers excellent output thanks to its high working speed of up to 20 km/h. Good soil crumbling is achieved by the relatively small (ø 52 cm), fast-rotating discs. The notched concave discs provide excellent penetration and intensive work. The paired disc arrangement increases the harrow's throughput.

The Horsch Joker RT can be fitted with DoubleRollPack or DoubleSteelDisc universal rollers, which deliver good results even on heavy soils. There is no need to adjust disc angle or offset; only the working depth has to be set.
