Einböck’s New AEROSTAR-EVO Harrow: Indirectly Sprung Tines, Hydraulic Downforce, and Precise Ground Following

The Austrian manufacturer Einböck has expanded its line of tine harrows featuring indirectly sprung tines, introducing the AEROSTAR-EVO - a lighter, more cost-efficient concept designed for modern mechanical weed control in arable crops. The core idea behind the new model is to combine gentle work on emerging crops with the ability to more aggressively break soil crust when conditions demand it.

What’s new in AEROSTAR-EVO - and why it matters in the field

1) Indirectly sprung tines with hydraulic downforce up to 4.5 kg

Each tine can be loaded hydraulically within a range from its own weight up to 4.5 kg, giving the operator a broad tuning window for different crop stages and soil conditions - from light “blind harrowing” to more intensive crust breaking.

2) Geometry for uniform coverage: 3.125 cm tine spacing and 1.5 m sections

For consistent full-width coverage, the manufacturer specifies 3.125 cm tine spacing, and a standard 1.5 m harrow section carries 48 tines. This dense “tine footprint” is particularly valuable when the goal is maximum uniformity and minimal skips, especially during early passes.

3) Ø7 mm tines, 500 mm tine length, increased clearance

AEROSTAR-EVO is specified with 7 mm diameter tines and 500 mm tine length - positioned as a robust setup that maintains reliable performance even when crops are more developed (later passes), supported by clearance and tine stability.

4) Hydraulic tine lift as standard equipment

Einböck also highlights hydraulic tine lift (switching to transport position) as standard, with optional features available depending on configuration, including components that influence working “aggressiveness.”

Spare parts and made-to-order components

If your farm operates machinery from different brands, you can purchase spare parts for agricultural equipment from BAS-Agro LLC (Cherkasy, Ukraine) at https://bas.ua/. The site also has a dedicated section for spare parts for tillage equipment: https://bas.ua/shop/spare-parts-for-tillage-equipment-000000029-1. A practical advantage is that BAS-Agro can also manufacture parts based on a drawing or a sample, which is particularly useful when a non-standard component is needed or when a unit must be restored quickly.

AEROSTAR-EVO technical data (manufacturer-published)

Below are key parameters published by Einböck for the AEROSTAR-EVO model range: working width, weight, power requirement, and number of tines.

General (standard) specifications stated by the manufacturer:

• tine spacing: 3.125 cm
• section width: 1.5 m, 48 tines per section, 6-row sections
• tines: Ø 7 mm, 500 mm length, individually replaceable
• downforce: up to 4.5 kg per tine (hydraulic)
• frame clearance: 490 mm
• for the 12 m version, the published reference is ~1700 kg base weight and operation from ~100 hp

Where AEROSTAR-EVO fits best in crop technology

Based on the manufacturer’s positioning and the industry news description, AEROSTAR-EVO targets typical mechanical weed control tasks in cereals, maize, and soybeans, as well as sugar beet and sunflower - in other words, applications where you need a combination of precision at early stages and the ability to “push harder” against crusting or a flush of weed seedlings at the right timing.

Conclusion

AEROSTAR-EVO appears to be a logical next step in Einböck’s tine harrow evolution: dense tine spacing, indirect springing, and hydraulic downforce control provide a precise adjustment tool for soil and crop stage, while a broad range of working widths (from 3 to 15 m, plus 18 m in the published lineup) supports different farm scales.
