How to choose a spring harrow: straight or tine harrow for different crops and growth stages

How to Choose a Spring Harrow: by Crop, Growth Stage, and Tillage Period

Choosing the right spring harrow is one of the key factors affecting soil cultivation efficiency, weed control, and final crop yields. In practice, farmers most often choose between two solutions: a spring harrow with straight tines and a spring harrow with striegel (harrow comb) tines. These implements solve different agronomic tasks and are used at different stages of crop vegetation.

Grand Max Agro is a full-cycle Ukrainian manufacturer specializing in the production of spring harrows of the Grand MAX EcoTerra 3.0; 6.0; 9.0 series (straight tines) and Grand Max EcoTerra Striegel 3.0; 6.0; 9.0 (striegel tines). Below, we explain which harrow to choose and when.

Spring Harrow with Straight Tines: When Intensive Cultivation Is Needed

Straight tines (10 mm) provide a more aggressive impact on the soil. This type of spring harrow works effectively on compacted soils, breaks surface crusts, and seals in moisture.

Optimal application period:

• early spring

• pre-sowing soil preparation

• pre-emergence period

• stubble cultivation

Results for the farm:

• moisture retention and reduced evaporation

• destruction of weeds at the “white thread” stage

• field leveling

• improved soil structure

• yield increase of 5–10%

Recommended models:
Grand MAX EcoTerra 3.0; 6.0; 9.0

Striegel Spring Harrow: Ideal for Working on Emerged Crops

The striegel (S-shaped) tine provides gentle “combing” of the soil and plants. It is the best choice for mechanical weeding and organic farming.

Optimal application period:

• work on emerged crops

• 2–6 leaf stages

• interstage cultivation

Results:

• weed control without herbicides

• soil aeration

• no crop damage

• uniform and even emergence

• reduction of crop protection costs by up to 50–70%

Recommended models:
Grand Max EcoTerra Striegel 3.0; 6.0; 9.0

Universal Approach — Maximum Benefit

For farms with diverse crops, the optimal solution is a harrow with the ability to change the type of tines. This allows the use of straight tines in spring and on stubble, and striegel tines on emerged crops.
