The Grand Max EcoTerra support wheel set (4 pcs) is a professional solution designed to improve the accuracy, stability, and efficiency of spring harrows during mechanical weeding, early spring harrowing, and crop emergence cultivation.
This set is specially developed for EcoTerra and EcoTerra Striegel series spring harrows and ensures precise ground contour following, stable working depth, and minimal load on the tractor.
The set of four support wheels is intended for use with wide working-width spring harrows and is applied in cases where maximum precision and gentle soil treatment are required.
The set is especially effective for:
crop emergence cultivation;
mechanical weeding;
organic farming;
operation on uneven fields;
use with harrows 6–9 m wide and larger.
The four-point frame support prevents section sagging and ensures stable machine geometry across the entire working width.
The set is equipped with wide, European-made support wheels featuring high wear resistance and reliability.
Diameter: 420 mm
Tire size: 18×8.5
Width: 215 mm
The increased wheel width ensures even load distribution and completely prevents soil compaction, even when working on wet or light soils.
✔ The harrow rolls smoothly instead of being dragged;
✔ Reduced load on the tractor’s hitch;
✔ Lower rolling resistance;
✔ Fuel savings;
✔ Improved terrain following;
✔ No soil compaction;
✔ Preservation of soil structure.
Thanks to the wide profile, the wheels do not form ruts and do not disturb the root zone.
The set of 4 support wheels is mandatory for the following models:
EcoTerra Striegel 3.0
EcoTerra Striegel 6.0
EcoTerra Striegel 9.0
Striegel harrows operate on young crops and require maximum working depth accuracy. Without four wheels, it is impossible to ensure:
stable spring-to-soil contact;
uniform pressure on plants;
protection of seedlings from damage;
high-quality mechanical weeding.
For standard models:
EcoTerra 3.0
EcoTerra 6.0
EcoTerra 9.0
The four-wheel set is recommended when:
working on large areas;
using Ø7 mm and Ø10 mm springs;
operating at high speed;
working on uneven terrain;
high precision is required.
Under these conditions, four wheels provide maximum stability and extended equipment life.
When cultivating young plants, working depth accuracy is critical.
The 4-wheel set ensures:
✔ stable pressure of each tine;
✔ no section sagging;
✔ crop protection;
✔ uniform performance across the entire width.
For Ø7 mm springs, the use of four wheels is essential.
When working on open soil, two options are possible:
2 wheels — basic configuration;
4 wheels — maximum stability and control.
For intensive use and large areas, the 4-wheel set is strongly recommended.
✔ high working precision;
✔ no frame distortion;
✔ uniform working depth;
✔ crop protection;
✔ reduced spring wear;
✔ fuel efficiency;
✔ extended harrow lifespan;
✔ compliance with European standards.
The set design follows leading European manufacturers’ approaches and is adapted to Eastern European operating conditions.
Using the four-wheel support set allows you to:
reduce the number of repeat passes;
lower fuel costs;
reduce equipment wear;
increase crop yields;
shorten return on investment.
This is a profitable investment for farms focused on stable results and high profitability.
