LIRA – Spring-tooth harrow

LEGENDARY LIRA

Application of the LIRA harrow allows not only destroy weeds without expensive chemicals, but also moisture retaining and air access to seeds.

More than 16 years of successful work in the fields have made the LIRA spring harrow truly legendary! 

Its simplicity, reliability and the highest quality of work are familiar to farmers in Ukraine, Russia, Kazakhstan and many other countries.

APPLICATION

LIRA spring harrow is applied for:
• early spring harrowing for crust destruction and encouraging the weeds germination;
• weeds destruction in the “white fiber” phase;
• moisture retention by means of interruption of capillary flow from the substrate;
• even distribution of stubble remains on the field;
• incorporation of seeds and mineral fertilizers, distributed across the field;
• overall tillage when handling the fallow lands and seedbed preparation when fall-ploughing;
• windrowing of straw and hay.


ADVANTAGES


Lira_4.jpg — Improved cultivation quality

Working sections consist of five rows of the offset spring teeth with spacing of 38 mm. Such teeth location excludes noncultivated areas.

Careful cultivation provided by the adjustable tilt angle of teeth.The teeth tilt angle is adjusted for entire section with limits from 15° to 90°, and interval of 15°.

Blockage-free work of teeth and perfect loosening provided by vibration effect.

Lira_6.jpg— Precise and careful soil cultivation

With the chained individual working sections, the LIRA spring harrow perfectly follows any field contours in spite of its wide working width.

Special agricultural low-pressure tires almost fully eliminate the risk of damage to plants. Also there tires

Lira_8.jpg — Premium class spring tooth

Spring tooth is made of high-quality special steel with special double heat treatment. The spring tooth diameter is 10 mm, but application of innovative hardening significantly (in 2…3 times) increases the tooth wear resistance in the working area with high wear, wherein the areas under torque stress are highly strength.

Lifetime of our tooth is three times higher than tooth of other manufacturers.


Lira_1.jpg — Uniform distribution of crop residues

Combine straw choppers, especially with wide headers, not always optimally distribute the straw, which entails broken seedlings, uneven ripening and significant deterioration of the harvesting quality. The LIRA harrow can remedy the situation, distributing residues uniformly.

Lira_7.jpg — Forged cross

Forged crosses compared to welded ones provide high durability and reliability regardless of “human factor”.

— Simple folding-unfolding

One tractor driver can fold and unfold the harrow due to design of frame and hitch.

For quick folding/unfolding the LIRA harrow is equipped with transport wheels with adjustable toe angle.

Lira_10.jpg — Special agricultural low-pressure tires

Special agricultural low-pressure tires almost fully eliminate the risk of damage to plants. Also there tires eliminate overcompacting of the soil and don’t leave tracks.

Specific thread pattern allows drawing off the dirt and provides smooth running without adhesion of dirt even in overwatered conditions.

REFERENCES OF CUSTOMERS


Cultivation with the LIRA harrow facilitates water retention, air access to the seeds and roots of the plants, improvement of air circulation in the soil and increase of soil ability to absorb the atmospheric moisture, which appears due to temperature difference.



Lira_3eng.jpg Lira_2eng.jpg

Intensive snow melting, abundant rainfall between seeding and seedling emergence, which alternate with hot and dry weather, lead to soil crust with a large number of capillaries, by which the water from substrate lifts to the surface and evaporates.

Besides, surface crust blocks the air access to seeds, which considerably impairs their germination and leads to their partial destruction. On heavy floating soils the effect of soil crust may be catastrophic.
