The harrow HORSCH Cura ST is one of the central solutions especially for hybrid and organic farming. Due to the 6-bar, robust design the frame is extremely torsion-resistant even in large working widths and works precisely in all situations.
The Cura ST – efficiency and precision combined with robust harrow technology and a long service life for mechanical weed control
- Precise depth control due to the possibility of up to 11 support wheels
- Working widths from 6 to 24 m
- Robust, fully welded frame design
- Option: MiniDrill seeding unit
- Tines with an angle of 100° or 125° for all conditions
- Option: 60 mm carbide protection at the tines
- Tine pressure from 300 to 5 000 g allows for a wide range of applications – from blind harrowing to breaking crusts to keeping the soil brown
- Standard headlands position for Cura 9 ST to 15 ST
The combination of robust and precise harrow technology and a long service life for mechanical weed control. A tine pressure ranging from 300 to 5 000 g allows for using the machine in different soils and crops.
Efficient working widths from 6 to 24 m.
- Create false seedbed
- Harrow pre-emergence population
- Cereal population
- Maize from the 2- to 3-leaf stage
- Soya from 1. leaf

Features
Hydraulic tine pre-tension pressure with double tension spring
- Gradual adjustment with depth stop clips
- Variable adjustment of the tine pressure from 300 to over 5 000 g
The tine pressure can be adjusted gradually with depth stop clips from 300 to over 5 000 g.
Harrow tine standard 100° or 125°
- For harder and heavier soils with 100°
- For lighter and sandy soils with 125°
Harrow tines with 100° are ideal for harder and heavier soils and can mainly be used in cereals with a hard crust.
Harrow tines with 125° are ideal for lighter and sandy soils and are mainly recommended for soils with more organic residues.
Support wheel positions
The support wheels can be mounted ex factory to match the following row spacings:
- 25 cm
- 30 cm
- 45 cm (track width 1.80 m)
- 50 cm (track width 2.00 m)
- 70 cm (track width 1.50 m)
- 75 cm (track width 1.50 m)
Depending on the requirements, the layout of the support wheels is variable for all working widths. Either front and rear support wheel in one track – for row widths from 25 to 75 cm: in row crops the wheels run in the same track one behind the other. Or the support wheels are mounted in an offset way to make sure that the crop is not run over twice.
Additional Features
Electromagnetic valve to save one control device
- To save one hydraulic control device
- Two control device functions are combined
To save one hydraulic control device, it is possible to use an electromagnetic valve to combine two control device functions.
MiniDrill
- One or two seed towers depending on the working width
- To apply microgranular compounds or fine seeds
- 50 cm spacing of the deflector plates
- Optional: can be equipped with ISOBUS terminals
A MiniDrill can be mounted on all Cura ST from 6 to 15 m. Depending on the working width, one or two seed towers are required. The spacing of the deflector plates always is 50 cm to apply microgranular compounds or fine seeds. An ISOBUS terminal to operate the MiniDrill can be ordered as an option.
Following harrow behind the support wheels
- To loosen the tracks behind the support wheels
- To release run down weeds
- Option: separate harrow behind every wheel
To loosen the tracks behind the support wheels and to release run down weeds, a separate harrow can be mounted behind each wheel as an option. We recommend this option if the machine is frequently used in row crops or for pre-emergence harrowing.
Infinitely variable tine pressure adjustment
- Infinitely variable adjustment of the tine pressure
- For very changing soils or varying population conditions
With this equipment, the tine pressure can be adjusted infinitely variable for example in very changing soils or varying population conditions. We recommend this option for crops like maize, soya and also sugar beet.
