Mounted Spring Harrow Grand Max EcoTerra Striegel - Standart Mini 3.0
(Striegel spring 7×470 mm)
The Grand Max EcoTerra Striegel - Standart Mini 3.0 spring harrow is a compact, maneuverable, and professionally reinforced mounted implement designed for gentle surface soil cultivation. This 3-meter striegel harrow has been specially developed for organic farming, eco-farms, agricultural enterprises, and resource-saving technologies, where it is important to work carefully on emerging crops, effectively control weeds without chemicals, and preserve soil structure.
The model is manufactured by the Ukrainian plant Grand Max Agro, which carries out the full production cycle: design, metal selection, welding, assembly, sandblasting, and painting. This ensures consistent quality, structural reliability, and adaptation of the harrow to real operating conditions on Ukrainian soils.
Purpose of the EcoTerra Striegel - Standart Mini 3.0 Harrow
The Grand Max EcoTerra Striegel - Standart Mini 3.0 spring harrow is used for:
• gentle loosening of the topsoil layer to a depth of 0–4 cm
• breaking the soil crust and improving aeration
• conserving moisture in the upper horizon
• mechanical destruction of weeds in the “white thread” stage
• delicate care of emerging crops without damaging plants
• leveling the field surface after sowing
• processing stubble and crop residues
• incorporating seeds and mineral fertilizers
The harrow works effectively on crops such as wheat, corn, sunflower, soybeans, rapeseed, vegetable crops, fallow, and stubble.
The main objective of application is a stable reduction of field weed infestation without herbicides, improvement of moisture and air exchange, activation of microbiological processes, and formation of uniform, vigorous crop emergence with a potential increase in yield.
Striegel Spring 7×470 mm — Gentle and Effective Operation
The harrow is equipped with 7×470 mm striegel springs made of hardened steel grade 70.
Advantages of this spring:
• soft yet effective impact on the soil
• minimal damage to cultivated plants
• efficient breaking of the soil crust
• pulling out filamentous weeds
• high elasticity and wear resistance
• resistance to metal fatigue
This option is ideal for organic farming, early spring harrowing, and crop care.
Reinforced Compact Frame
Despite the small working width, the frame of the Grand Max EcoTerra Striegel Standart Mini 3.0 harrow is made according to a reinforced design and is intended for long-term intensive operation.
Design features:
• front part of the frame additionally reinforced
• truss-type construction
• reinforced braces against twisting
• all highly loaded zones welded with gussets
• high-rigidity profile pipes
• use of steel grade 45 in critical units
• metal thickness — 5 mm
This design eliminates deformation, reduces vibrations, and increases the service life of the implement.
Working Tools and Adjustment
• 5 rows of paired striegel tines
• uniform pressure across the entire working width
• sectional layout
• angle of attack adjustment — 4 positions
Angle of attack adjustment allows precise setting of work intensity depending on soil type, moisture, crop growth stage, and field weediness — from a максимально delicate mode to more active loosening.
Support Wheels — Stability and Savings
The harrow can be equipped with wide support wheels of European manufacture.
Installation of 2 support wheels is recommended for better frame stability, uniform ground contour following, and more consistent cultivation quality.
▪️ For the 7 mm spring version, it is possible to:
• install 2 support wheels
• or operate without wheels — depending on operating conditions and customer preferences.
Advantages of using wheels:
• the harrow rolls rather than drags across the field
• reduced load on the tractor hitch
• lower resistance to movement
• fuel savings
• improved ground contour following
• elimination of soil compaction
• increased cultivation stability
Aggregation and Technical Specifications
• working width — 3 m
• type of aggregation — mounted
• 3-point hitch (category 1 / 2)
• tractor power — from 30–50 hp
• working speed — 10–12 km/h
• productivity — up to 3–4 ha/hour
• simple adjustment and maintenance
• compact transport dimensions
The harrow is easily aggregated with MTZ, UMZ, and similar tractors, does not require complex maintenance, and can be operated by a single mechanic.
Economics and Benefits
Using the EcoTerra Striegel Mini 3.0 allows:
• reducing herbicide costs by up to 50–70%
• lowering expenses for crop protection products and fuel
• increasing yields
