Grand Max ECO TERRA UNIVERSAL 9 m Spring Harrow — a universal solution for professional soil cultivation
The Grand Max ECO TERRA UNIVERSAL 9 m spring harrow is a modern universal agricultural harrow designed for intensive farming, mechanical weed control, moisture preservation, and high-quality shallow soil cultivation. The model was developed by Grand Max Agro engineers based on real operating conditions in Ukrainian farms and combines high structural strength, a wide range of adjustments, and excellent adaptability to different farming technologies.
The key feature of this model is its universal sectional system, which is initially equipped with straight 10×500 mm springs but can also be converted to striegel springs or tooth spring sections upon request. This allows the harrow to be used both for aggressive loosening and breaking soil crusts, as well as for delicate crop treatment in organic farming.

Reliable construction for intensive operation
The Grand Max ECO TERRA UNIVERSAL spring harrow is designed for long-term operation under heavy loads.
The main frame is made of 140×140×8 mm profile tubing, ensuring:
✔ high structural rigidity
✔ resistance to deformation
✔ minimal vibration
✔ long service life under intensive use
The working sections are mounted on a four-link parallelogram suspension system, allowing the harrow to perfectly follow the field contour and maintain uniform working depth across the entire width.
The spring-mounted section connection ensures constant soil pressure and improves cultivation quality even in difficult field conditions.
Adjustable attack angle — precise settings for any conditions
The harrow is equipped with a 5-position attack angle adjustment system.
This allows operators to:
✔ change cultivation intensity
✔ adapt to different soil types
