How to choose a Grand Max spring harrow: without wheels, with 2 or 4 support wheels

Why 4 Support Wheels Are the Right Choice When Choosing a Grand Max Spring Harrow

When choosing a spring harrow for agriculture in Ukraine and Europe, farmers increasingly pay attention not only to working width, spring tine type, and frame design, but also to the number of support wheels. This parameter directly affects machine stability, working depth, crop safety, and final yield.

The Grand Max spring harrow is designed to operate with both two and four support wheels, depending on agronomic tasks and field conditions. This is not an unnecessary option, but a well-thought-out engineering solution based on the practical experience of Ukrainian and European farms.

Practice of Using Spring Harrows in Ukraine

In most agricultural enterprises, spring harrows are used in two main operating modes:

• With Ø7 mm spring tine – for working on seedlings and young crops
  (Striegel Harrow – EcoTerra Striegel 3.0 / 6.0 / 9.0)

• With Ø10 mm spring tine – for moisture retention, early spring harrowing, and field leveling
  (Straight Spring – EcoTerra 3.0 / 6.0 / 9.0)

For these working modes, the number of support wheels plays a key role in ensuring high-quality soil cultivation.

Working on Seedlings (Ø7 mm Spring Tine): Why 4 Wheels Are Essential

When harrowing young crops, the main goal is to maintain stable working depth and uniform pressure of spring tines across the entire working width.

Even minor deviations in depth can damage plants and reduce crop yields.

Advantages of Four Support Wheels:

✔ the harrow frame accurately follows field contours
✔ no “diving” of sections on uneven terrain and tractor tracks
✔ stable and predictable pressure on each tine
✔ minimized risk of crop damage
✔ uniform operation across widths of 7–9 m and more

With only two support wheels, long harrows tend to “flex”: the central section works steadily, while side sections may sink too deep or lose soil contact. When working on seedlings, this becomes a critical risk factor.

Therefore, for mechanical weeding, organic farming, and work with young crops, specialists recommend choosing Grand Max spring harrows with four support wheels.

Moisture Retention and Early Spring Cultivation (Ø10 mm Spring Tine): 2 or 4 Wheels?

When working on open soil, stubble, or in early spring, accuracy requirements are lower than for seedling cultivation.

In this mode:

• working depth is less critical

• wider operating range is allowed

• main goal is breaking soil crust and conserving moisture

• field leveling is important

Available Configurations:

✔ 2 Support Wheels
— simpler design
— lower weight
— optimal price
— sufficient stability for moisture retention

✔ 4 Support Wheels
— maximum depth control
— better uniformity
— high stability on uneven fields
— comfortable operation at large working widths

The Grand Max spring harrow allows you to select the optimal configuration without compromising cultivation quality.

Spring Harrow Without Wheels: Basic Solution for Simple Tasks

Some farms use models without support wheels, especially on small areas.

Suitable if:
✔ fields are flat
✔ working area is limited
✔ low-power tractors are used
✔ basic operations are performed

Advantages:

✔ minimum cost
✔ simple construction
✔ low weight

Limitations:

◯ limited depth control
◯ instability on uneven terrain
◯ not recommended for seedling cultivation

Wheel-less harrows are usually chosen by farmers who want to minimize initial investment.

European Approach and Grand Max Experience

Leading European manufacturers of spring harrows (Einböck, Hatzenbichler, APV) use multi-wheel frame systems for seedling cultivation.

The standard for 6–9 m machines includes:

• 4–6 support wheels

• uniform load distribution

• priority of geometry over weight

The main European principle is not to increase machine weight, but to ensure structural stability.

This principle is integrated into the design of Grand Max spring harrows, adapted to real field conditions.

Compatibility with the Grand Max Product Line

All Grand Max spring harrow models can be equipped with:

• no support wheels

• two wheels

• four wheels

This makes it possible to select equipment for specific crops, soil types, and cultivation technologies without overpaying for unnecessary options.

Which Option to Choose: Quick Recommendations

Choose a harrow without wheels if:
✔ you work on small fields
✔ you perform simple tasks
✔ you have a limited budget

Choose a 2-wheel harrow if:
✔ you focus on moisture retention
✔ you prepare the seedbed
✔ you need a versatile solution

Choose a 4-wheel harrow if:
✔ you work on seedlings
✔ you practice mechanical weeding
✔ you use wide working widths
✔ you apply organic farming methods
✔ you need high precision
