How to choose a spring harrow: straight or tine? Farmer tips from Grand Max Agro

Spring Harrow: Straight or Striegel Tines — What Should a Farmer Choose?

When choosing a spring harrow, many farmers face the key question:
which is better — a harrow with straight tines or with striegel (S-shaped) tines?
Both options solve different agronomic tasks and are suitable for different crops, growth stages, and soil cultivation technologies.

Grand Max Agro is a Ukrainian manufacturer of spring harrows from the Grand Max EcoTerra line and produces both types:

• with straight tines: Grand MAX EcoTerra 3.0; EcoTerra 6.0; EcoTerra 9.0

• with striegel tines: Grand Max EcoTerra Striegel 3.0; EcoTerra Striegel 6.0; EcoTerra Striegel 9.0

Let’s take a closer look at their differences and which harrow is best for specific farm tasks.

1. Spring Harrow with Straight Tines — Universal and More Aggressive

A straight tine (single tooth) is a rigid, hardened steel spring with a diameter of 10 mm, designed for intensive loosening and breaking of soil crust.

Characteristics:

• high rigidity

• working depth: 3–6 cm

• effectively breaks dense soil crust

• excellent moisture sealing

• performs well on stubble and compacted soils

Advantages:

• versatility for different conditions

• suitable for all soil types

• handles large clods and dense crusts

• can be used both before and after emergence (with caution)

Where it is used:

• early spring moisture sealing

• pre-sowing soil preparation

• weed control at the “white thread” stage

• stubble loosening

• field leveling

By crops:

• wheat — early spring

• barley, oats — moisture sealing

• maize — pre-emergence

• sunflower — up to 4 leaves (with caution)

• soybean — not recommended on emerged crops

• rapeseed — pre-emergence only

Conclusion:
Straight tines are an aggressive and universal solution for most farms.
They are ideal for spring operations, moisture sealing, and crust control.

✔ Suitable if you need a classic, reliable harrow for tough conditions.

2. Striegel Tines — Gentle and Ideal for Working on Emerged Crops

Striegel tines (double S-shaped) consist of two thin, flexible springs that create a “combing” effect on the soil surface.

Characteristics:

• soft and flexible operation

• working depth: 1–3 cm

• ideal for early growth stages

• does not damage crops even at high plant density

Advantages:

• gentle weed control

• improved soil aeration

• softly removes soil crust

• levels the field surface

• safe for delicate crops

• optimal for organic farming

Where it is used:

• work on emerged crops

• interstage mechanical weeding

• crop care without herbicides

By crops:

• soybean — the best option on emerged crops

• maize — 2–6 leaf stage

• sunflower — 2–4 leaves

• wheat, barley — aeration and crust control

• rapeseed — no crop injury

• vegetable crops — delicate cultivation

Conclusion:
Striegel tines are the best solution for post-emergence work and organic technologies.
They provide gentle cultivation without damaging plants.

✔ Suitable if you work with soybeans, maize, rapeseed, and vegetables.
Models: Grand Max EcoTerra Striegel 3.0; 6.0; 9.0
